Agriculture and Dairy Education

Revered Prof. Prem Saran Satsangi, on 6th of July 2014, while explaining the Dayalbagh Way of Life and Agriculture and Dairying forming the fifth component of the Sigma Six Q model, stated, “Agriculture gives us opportunity to do selfless service and it is recognized in the country that there is still great opportunity to develop agriculture. It won’t be enough if we give emphasis to industry only. If we want to reach our progress in the country to all sections of people in Society, it is necessary to introduce entrepreneurship, innovation etc. in agriculture also for realizing desired progress and development”.

Agriculture Operations is an essential element of the education system at the Dayalbagh Educational Institute (DEI). In the article below, Prof. Prem Kumar Dantu takes us through the 
‘Agriculture and Dairy Education at DEI.

Eat well,

Prof. Dantu writes...

Agriculture operation in Dayalbagh has a hundred-year history. It is a need-based, sustainable, eco-friendly, and a scientific endeavour. Dayalbagh is self-sufficient in food for its residents and pilgrims and produces enough green fodder and bhusa (straw) for its Gaushala (Cowshed). In addition, it produces several fruits and herbs for Dayalbagh Pharmacy. Most of the agriculture operations are performed on a voluntary basis. This voluntary seva (selfless service) based agriculture model, on a smaller scale, is also practiced in Dayalbagh colonies in other parts of the country, such as Rajaborari and Timarni in M.P., Murar in Bihar, MTV Puram in Tamil Nadu, and Kakinada and Vishakapatnam in Andhra Pradesh. Hundreds of volunteers work together in the farms, every morning and evening irrespective of their age, gender, class, caste, and status.

Turning of harvested wheat plants
The Education Policy of Dayalbagh Educational Institute, penned by Revered Dr. M. B. Lal Sahab, highlights the importance of Agriculture Operations as an essential element of the education system of the Institute. The Policy also emphasizes that the Head of the Institute, himself/ herself have an “active involvement in field work so as to infuse staff and students with enthusiasm”. Dayalbagh agriculture operates on scientific principles for which there is a RSSAF Scientific Advisory Committee.

Demonstration of Power Thresher
Agriculture Operations and Rural Development are mandatory core courses for students of all streams in DEI, with students participating in and getting hands-on training in all aspects of agriculture. Further, under NSS, students participate in various farm related and rural development activities. On Sundays, students in large numbers do field work. Students also participate in Gaushala maintenance, Dairy, herbal garden maintenance, biodiversity park development, and mushroom cultivation.

Demonstration of Disc Harrowing
There are plans to start precision farming to optimize utilization of manpower, irrigation water, and soil addendum, and to train students in the modern methods of cultivation. DEI has initiated agriculture education by starting undergraduate courses in B.Sc. Applied Botany and B. Voc. Agriculture Technology and an MBA programme in Agriculture Management.

Harvesting of Barseem
Activities in Progress

Energy conservation and reducing Diesel usage

Wheat, Gram, Mustard, Masoor, Baajra, Barseem and Barley are sown in Dayalbagh every year. Threshing is done to take out the seeds from these crops. The threshers are driven by 3-phase AC induction motors, with the system designed in DEI in collaboration with the Agriculture Department of Dayalbagh.


The electric distribution system for running the threshers with electric motors is designed in DEI with protections, metering, and alarms and appropriately sized cables to minimize voltage drop and losses. Three of the threshing machines run on solar power generated in DEI, reducing the electricity consumption from the Grid and potential downtime due to power failure. A dedicated solar power plant of 50kWp capacity is installed in the Dairy and Agriculture complex. A 20kW capacity Bio-gas plant is being commissioned and will be integrated through a Smart Micro Grid.

Ground water conservation through rain water harvesting and use of sewage treated water
Much of the agricultural irrigation in Dayalbagh is done through sewage treated water from the Sewage Treatment Plant (STP) situated at Dayalbagh. DEI helps Dayalbagh maintain the STP motors for pumping the treated water into canals for irrigation. A Short Messaging Service (SMS) based embedded system for remote monitoring and control of STP pumps has been designed and deployed by the students of DEI.



Integrated solar farming with remote controlled solar assisted micro-irrigation system for local energy use and better farm productivity
The concept of a solar agriculture farm is being developed in DEI. A novel sun-tracking structure has been developed that accommodates 50 solar modules at a minimum ground clearance of 12 feet, thereby facilitating multiple land use, viz. solar-agriculture farm where agriculture can be performed in the land beneath the solar modules. Combination of solar farming with agriculture increases the land yield. The cost of module support structure is compensated by the cost of the land salvaged. This will allow for a through the year solar crop even if the agricultural crop gets affected due to insufficient rains/ otherwise. These multiple land use models would allow large MW size solar plants to be installed near load centres and sub-stations, reducing the cost of grid infrastructure required when these solar power plants are installed on distant barren lands.


Mobile SPV plants for irrigation and other applications
Mobile SPV plants are being developed at DEI which are mounted on a trolley or a vehicle to be used for irrigation in rural areas where erratic or absent electric supply. The vehicle may be towed using a tractor with the SPV modules folded. Whenever required, the SPV modules can be unfolded (manually or motorized) to capture sun light and can power the irrigation pumps or for other uses. A multi-purpose variable frequency drive may be used for irrigation pumps as well as other applications. Typical sizes are 2 – 5 kWp capacity.

Proposed activities

Village Distributed Energy Resource (DER) Grid
Design and development of village DER Grid which would comprise of Irrigation Micro Grid and Residential Micro Grid with possible interoperability. Both micro grids have different load profiles and hence the separation.

Renewable energy solutions for completing the value chain for farmers located at remote places without access to reliable electricity
Extending the village DER grids/ designing efficient and economic stand-alone SPV plants to power cold storages, driers, winnowers, flour/ dal mills, husking machines etc. and complete the value chain for empowering the farmers at remote locations to grow crops of their choice and to get better agricultural land yields.

Data aggregation, data analytics, Machine Learning applications for Village micro grids
Precision agriculture involving sensors, embedded controllers and drip irrigation systems are going to be essential for future organic agriculture. Integrating the sensor data, weather logs and the solar data logs would be useful for efficient irrigation and precision farming. Modern Machine Learning techniques can be used to study and infer potential threats, economics and reliability of the system. Development of such handy software tools will help ensure efficient, economic and reliable operations of DER micro grids encompassing precision agriculture. Cloud storage servers would enable remote monitoring, analysis and control of village DER grids and agriculture.

Drones for precision farming application and surveillance
It is proposed to work on this area for localizing weeds and diseases, determining soil properties, detecting vegetative differences in farms associated with Dayalbagh. However, because of legal restrictions the drone payload should not exceed 5 kg.

Sustainable Development Solutions through Strategic Planning in Agriculture via Interactive Management Strategy
Idea Engineering, Fuzzy DELPHI, Option Field and Option Profile Methodologies along with Scenario Building Exercise and many other techniques of interactive management and system design to be utilized for solutions using Second Generation System Design Paradigm for the said sustainable agriculture initiatives. Such initiatives at sub-system level in Dayalbagh Farming System may be a starting point where deliverables could be used and closely monitored for further nurturing and modifications.

Hydraulic Ram (HYDRAM) for water lifting as a green irrigation initiative
The use of eco-friendly HYDRAM at different identified locations in the farm may reduce costs. A pilot study on use of HYDRAM is proposed.

Sprinkler Systems as Rain-fall Simulators
Besides, other promising areas viz. pico power generation, environmental protection practices, technology assisted organic farming, training and learning initiatives for farmers, students and stakeholders can also be explored and pursued.

Rural Development and Empowering Rural Women

DEI has embarked on a new educational pedagogy of engaging, educating, and improving skills of the rural women. In the remote tribal zones of Madhya Pradesh, ADyNaM (Agri Dairy Nano Processing of Multi-products) Foods has been set up. ADyNaM is a facility for processing of the agricultural and dairy-based raw produce to make secondary products. Women are trained on the production of pickles, chutney, amla candy, and squashes. Recently, a level-1 food testing laboratory has been setup to implement quality control, and to comply with the food safety standards.

Agriculture Education at DEI

In order that the experiential knowledge that Dayalbagh and DEI collectively possess benefits the society at large and contributes to the Nation, Faculty of Agriculture is proposed to be established by DEI after obtaining the necessary approvals and permissions. The Department of Botany got approvals from UGC to start two new courses namely B.Sc. (Hons) Applied Botany and B. Voc. Agriculture Technology from 2017. The Department of Management has initiated an MBA programme in Agriculture Management from 2017 session.

Agriculture Operations in Dairying

RSS (Radhasoami Satsang Sabha) Gaushala in collaboration with DEI is transforming into a state-of-the-art Gaushala with the use of RFID, ICT tools, management software, sensors, and modern practices for precise management of nutrition, health, and breeding of cattle. The objective is to develop RSS Gaushala and DEI into a centre of excellence for precision Dairy Farming and Dairy Technology. The effort is to increase milk yield by improving nutrition, health, and breed of the cattle.

Breeding: Database management for maintaining all breeding records using precision Dairy farming software system. The database also records data on heat/ A.I./ calving/ milk yield/ treatment etc. are maintained.

Feeding: Feed planning originates from cultivation of our own crops. Extensive agricultural operations spread over 800 acres and wide range of crops balanced between crops for human and animal consumption is maintained. Each product of crop & its by-product is utilised. Emphasis is on quality & quantity of green fodder, which is the natural and cheapest source of protein. Silage preparation is also done to cater for the lean period.

Facilities Management: Wi-Fi network across the Gaushala provides ready access of information, which is critical for taking spot decisions. There is category & age group-wise housing of the herd. There is a platform weighing scale for monitoring the weight and growth of cattle (calves and heifers). Other B. Voc. Agriculture Technology students sowing groundnut facilities include a cattle bathing shower, similar to a car wash, where the water used for bathing feeds the buffalo pond and thereafter taken for cultivation of crops after getting enriched in urine & cow dung slurry. There is a cow brush parlour, with a sensor-based scrubber and timer. The rotatory movement with brushes relaxes the cows during idle time by reducing itching and increasing blood circulation. The eco-friendly sheds with thatched roofing maintain temperature during summers & winters. Other activities to reduce cattle stress:
  • Playing of devotional music during milking
  • Giving names to each cow & conversing with them using their names
  • Access to clean & fresh drinking water at all times
  • Improving ventilation in sheds by lowering of brick walls
  • Installation of fans in high yielder shed
  • Using thatched roofing in new sheds
  • Khus-chick curtains with drip system and misting are being experimented to reduce the heat stress of the cattle


Dairy Technology Activities in Dayalbagh

Cupid is a logo of REI Dairy products. REI Dairy has been judged as Asia’s best and world’s second-best dairy. On 8th January 1934, Cupid Butter landed in United States after travelling 10,000 miles for 45 days over land and sea without refrigeration and scored 91 points as compared with the score of 92 points scored by the best fresh butter produced in America. Several dignitaries, who visited REI Dairy whole heartedly praised its efficient and professional operations and the quality of its products. In 1935, during his visit to Dayalbagh, Lord Willingdon, Viceroy and Governor General of India, was pleased to call it “the most efficient” Dairy seen by him in many years. Cupid butter was awarded Certificate of Merit in the All India Exhibition of Arts and Industries in Punjab. In 1938, a six months Certificate course on practical training in Modern Dairying and Livestock Management was started at REI Dairy. In 1943, the efficiency of the dairy received a further testimony from the American Forces in Agra, when during 1943-45, they decided to get all their supplies of milk from this Dairy in preference to the Military Dairy in Agra.

Dairy Education at DEI

In 1994, the Dairy became a part of DEI, and work experience training in Dairy products was initiated. In 2015, DEI became the first Deen Dayal Upadhyay Kaushal Kendra in the country with Vocational Programmes in Dairy Technology. Under Kaushal Kendra, B. Voc., M. Voc. and Ph.D. Programmes in Dairy Technology have been approved by UGC. From the 2015-16 session, B. Voc. (Dairy Technology) was launched.

An experimental mini Dairy plant has been setup for providing in-house training to the students. Using this facility, students produce a variety of nutritional value-added dairy products, which not only caters to the needs of the local community and DEI on non-commercial basis, but also gives them practical exposure to entrepreneurship in Dairy Sector. DEI is privileged to have the first student run mini dairy plant in Northern India with FSSAI License, HACCP certification, export permit from Export Inspection Agency, Govt. of India, and commercial permit from US Department of Agriculture for the export of flavoured milk and butter.

The emphasis of these programmes is on entrepreneurship. The B. Voc. (Dairy Technology) has also been launched at the DEI ICT Centre at Amritsar. In December 2016, under Pradhan Mantri Kaushal Vikas Yojana for Technical Institutions through AICTE, a certificate course on Dairy Equipment Operator has been launched. Mini Dairy plants are also being set up in DEI ICT Centres at Amritsar, Timarni and Rajaborari. The objective is to reach out to other regions including remote parts of the country, and provide quality vocational programmes, and contribute to the mission of skilling, entrepreneurship in a scaled up and accelerated mode.

Smart Renewable Energy Microgrid at Dayalbagh Educational Institute

Some weeks back we introduced you to the Renewable Energy efforts at Dayalbagh Educational Institute (DEI). We get a bit more technical this week and introduce you to the,
Smart Microgrid developed and implemented by the Institute.

The post is by Prof. Bhagwan Das, Professor of Renewable Energy in the Department of Electrical Engineering at DEI.

Prof. Bhagwan Das writes...

In order to carry out sustainable developmental activities in agreement with the concept of Eco-Village, DEI took bold initiatives in harnessing the renewable energy through Solar thermal and Solar Photovoltaic (SPV) power plants in 2010. Today, the institute has Solar Thermal Cooking systems in all the hostels. The whole university campus is powered by 11 Distributed Roof-Top Solar PV power Plants aggregating to a total of 668.2 kWp. 


To ensure efficient, reliable and economic operation of the distributed energy resources and achieve proper coordination among them, a need based R&D project to indigenously develop a Smart Micro Grid in the institute was started with support from DST’s Solar Energy Research Initiative (SERI) in 2014.


The Dayalbagh renewable energy smart microgrid is a modern, small scale electricity system comprising a group of distributed loads and distributed renewable energy resources acting as a single controllable entity in synergy with the grid. It is designed to achieve specific local goals, such as energy reliability, security, carbon emission reduction, diversification of energy sources, and cost reduction. Such smart microgrids are an ideal way to integrate renewable resources and form the building blocks of Smart Grids.



All the solar power plants at DEI are Hybrid PV Power Systems with battery storage to facilitate off-grid operation whenever required. The three phase DSP based, Grid Support Conditioners (GSC) are designed to operate as a multi-function power conditioning unit combining renewable energy sources on priority with the functionality of an industrial UPS system.


The effectiveness of renewable energy microgrid was evident during the major grid collapse on two consecutive days on 30th and 31st July 2012 in India when over 600 million people (nearly half of India's population), in 22 out of 28 states in India, were without power. The outage caused "chaos" for Monday morning rush hour, as passenger trains were shut down and traffic signals were non-operational Trains stalled for three to five hours. Several hospitals reported interruptions in health services, while others relied on back-up generators. Water treatment plants were shut down for several hours, and millions were unable to draw water from wells powered by electric pumps. Excessive use of diesel generators (a popular backup resource) caused local pollution and high cost for the consumers. However, Dayalbagh Educational Institute, having its own SPV microgrid, was not affected and the teaching – learning- co-curricular activities continued normally in a pollution free environment and economic fashion. Even on normal sun-shine days, the institute is self- sufficient in power and not affected by the frequent power outages. Under cloudy conditions, a careful battery management ensures uninterrupted power supply to the whole campus.  



INNOVATIVE FEATURES & BEST PRACTICES
The following features are being incorporated as part of the R&D project to develop the smart micro grid with remote monitoring, communication, control and fault diagnosis of DERs from a central control station, which would ultimately enable the development of a Decision Support System for Optimal efficiency, economics and reliability. 

  • Display of Inverter parameters viz.  inverter voltage, current,  power, grid source for inverter parameters, solar current, voltage, power, solar irradiance, ambient temperature, heat sink temperatures, data logs etc. All of these parameters can be accessed from the central control station through our institute LAN. As per the requirement, the inverter behaviour can be controlled by remotely changing the software set points and selecting different modes of operations. All the inverters are on the institute LAN and accessible remotely through the front end program.

  • Display of Load Parameters through integration of Smart Meters: Load currents, voltages, powers on all the outgoing circuits can be accessed at the central control station through smart meters over the institute LAN.

  • Remotely controlled switchgear and change-over switches: Change-over switches for the selection of source (grid or solar) are installed for every outgoing circuit in various control rooms. A system has been designed and implemented to monitor the status of the switches and remotely control the selection through the software at the central control station.

  • Battery charging: Battery charging is a very important feature of the system affecting the life of the battery and overall system efficiency. Battery charging is to be closely monitored and controlled so as to utilize the solar power fully and ensure float operation of the battery as far as possible. Grid charging schedules (in rainy, cloudy days) for all the 9 power plants are carefully scheduled to prevent overloading of the sub-station. 

  • Water Pumping: A scheme is being designed for remote monitoring and control of water pumps in the institute for punctual and efficient operation of water pumps. This will be integrated to the central control system software. A prototype with remote control and monitoring using Short Messaging Service on GSM mobiles has been developed and implemented for field testing.

  • String monitoring and fault diagnosis: With thousands of panels in the institute, it is difficult to identify a mal-functioning panel. The requirement has prompted development of a ZigBee based wireless monitoring system for string current measurement. All the measurements of a plant would be collected at a central computer for processing and analysis. An alarm would be raised if some string is found to be mal-functioning along with the geographical location of the string. A prototype of the same has been developed. 

The Dayalbagh Educational Institute initiative has demonstrated that Universities, building intellectual resources through teaching-learning and research, offer a perfect platform for establishing renewable energy microgrids. In addition to sustainable development through clean energy technologies and self-sufficiency in energy, a university microgrid is an ideal test bed for conducting indigenous research and development through UG & PG projects and Ph.D. thesis. This would ensure quality research with relevance as well as development of skilled man power and intellectual property in the area. Universities can design and implement model curriculum for vocational diploma and certificate courses in solar energy technologies, provide earn-while-you-learn schemes to the students and encourage entrepreneurial start-ups through incubation cells.

Renewable Energy Initiatives at Dayalbagh Educational Institute


Renewable Energy initiatives at Dayalbagh Educational Institute


The first of our invited posts is by Prof. Bhagwan Das, Professor of Renewable Energy in the Department of Electrical Engineering at Dayalbagh Educational Institute (DEI). In this post, we will delve into the renewable energy initiatives at DEI.

Through the vision, initiative and encouragement of Revered Prof. Prem Saran Satsangi, Chairman, Advisory Committee on Education, Dayalbagh, the renewable energy deployment in the institute commenced in 2010 to facilitate sustainable developmental activities in agreement with the concept of an Eco-Village.

The university campus is powered by 11 Distributed Roof-Top SPV (Solar Photovoltaic - https://en.wikipedia.org/wiki/Photovoltaic_system) power plants aggregating to a total of 668.2 kW(peak). Apart from the Dayalbagh campus of the institute, distributed Roof-Top Solar PV Power Plants of aggregate 45 kWp capacity have been installed at DEI extension centers (ICT centers) in various cities and a CSR sponsored project of 200 kWp distributed off-grid SPV system is under commissioning in the Dayalbagh Rajaborari Estate of Madhya Pradesh tribal area.

The effectiveness of renewable energy micro-grid was evident during the major grid collapse on two consecutive days on 30th and 31st July 2012 in India when over 600 million people (nearly half of India's population), in 22 out of 28 states in India, were without power. Dayalbagh Educational Institute, having its own SPV micro-grid, was not affected and the teaching – learning- co-curricular activities continued normally. On normal sun-shine days, the institute is self- sufficient in power and not affected by the frequent power outages. Under cloudy conditions, a careful battery management ensures uninterrupted power supply to the whole campus.

Having commissioned the distributed SPV based micro-grid of the institute, the challenge now is to make the system efficient, reliable and economically viable in the face of dynamic loading conditions, weather conditions affecting generation and unreliable power grid. Multi-dimensional R&D activities are in progress to indigenously develop integrated remote monitoring, communication, control and fault diagnosis of all the power plants from a central control station, resulting in a Smart Micro Grid.



  Solar thermal cooking systems in Hostels  

Three solar thermal cooking systems have been installed in the three hostels in DEI. Each system comprises of 5 dishes, each having a 16 Sq m in diameter. The total average kcals generated by the concentrators in one system is 200,000 kcals / day, which is equivalent to 19 kgs of LPG. The system installed in the Girls’ Hostel is also equipped with water heating facility. For institutions having much larger hostels, the savings would be sizable.

The cooking systems are used for boiling Amla and decoction of herbs for preparation of Chyavan Prash in the Ayurvedic Pharmacy of Dayalbagh during their lull phase. With conventional boiling process, there was a requirement of 80 Kg of Hard Coke and the process time was 12 hours. In steam cooking the process time has reduced to 3 hours with no expenditure on fossil fuels.

A pioneer in the field of vocational education, the institute has launched vocational programmes in renewable energy at various levels viz. Certificate, Diploma, B.Voc., M.Voc. and Ph.D.



The Dayalbagh Educational Institute initiative has demonstrated that Universities, building intellectual resources through teaching-learning and research, offer a perfect platform for establishing renewable energy micro-grids. In addition to sustainable development through clean energy technologies and self-sufficiency in energy, a university micro-grid is an ideal test bed for conducting indigenous research and development. This ensures quality research with relevance as well as development of skilled man power and intellectual property in the area.

Look forward to your comments and feedback.

Sigma Six Q: Air Quality - The Second Quality


As a symbol, Sigma (Σ, σ) is used to typically denote a “mathematical sum” or “standard deviation”. In our context, it is a “sum” and to quote Revered Prof. Prem Saran Satsangi, “Sigma means that all these (six) aspects or components have interaction amongst themselves and the cumulative effect of all these is many times more than their individual effect.”

In the words of Revered Prof. Prem Saran Satsangi, “You are nowadays witnessing world-wide emphasis that environment does not get polluted and it is protected. For this purpose, SPHEEHA (Society for preservation of Health, Environment and Ecology and Heritage of Agra) is there, Supreme Court is there. All of them are taking steps for it. At this time, often it appears to be conflicting to the growth of industry. On this account, there are delays in the way of our progress. But, it is necessary to see whatever air and water is there in our environment, we should pay attention to their high quality, so that we are protected against diseases and lead a healthy life which is necessary if we want to achieve fully the ideal of Better Worldliness. Thus, there are two other excellence's in Quality – Air Quality and Water Quality which are inseparable parts of Dayalbagh Way of Life.”

The second Quality for a Sustainable Way of Life is Air Quality.


How does Dayalbagh ensure high standards of Air Quality?

The Dayalbagh campus is situated in garden settings, away from the din and noise of the city. Nestled between lush green fields, fruit bearing tree orchards, tree lined roads, it remains in harmony with nature.

Petrol (Gasoline) two-wheelers are not allowed inside the campus. Driving cars for commuting within the campus is restricted. Most men, women and children walk or cycle on the tree lined roads. This serves three purposes, people are healthier, promotes social equality and the air is sparkling clean. People who find it difficult walking/ cycling, utilize Cycle Rickshaw/ Battery operated e-Rickshaw service or Solar Augmented-Battery operated Bus.





There is a monthly 300-unit limit on residential grid power usage. Residences further augment this with clean solar power. Use of residential generators is prohibited. In the dry Agra summers, traditional methods of cooling or low power consuming coolers are utilized.

In terms of farming practices, there is a mix of manual and mechanized farming. All inhabitants (whether an academician or an entrepreneur or a person in service or a retiree) participate in community farming for a couple of hours each day. The community works together fostering a spirit of brotherhood, is healthier and need for mechanized farming reduces substantially. Further the Community Kitchen (Bhandar Ghar) uses Gasifiers for better efficiency and Solar-Thermal Cooking.

There is no burning of left over stalks post harvesting. These are utilized as Animal fodder or re-tilled into the land.




The cumulative effect of these is crisp and clean air, a quality necessary for a Sustainable Way of Life.

We look forward to your feedback. You can follow us on facebook (www.facebook.com/sigmasixq) and/ or on twitter (@SigmaSixQ). You can also subscribe to our posts via email (link on the right).



In the next post, we will cover "Water" quality.
