ICAR--Indian Council of Agricultural Research (2010 - 2015)

Under the auspices of Indian Council of Agricultural Research, New Delhi the present research centre functioning at Sri Parasakthi College for Women, Courtallam was started in the year 1977 by our Founder Principal Selvi. S. Baghirathi M.A., M.Litt., to undertake research regarding the conversion of any biodegradable waste into gas and manure. Since inception, the centre is involved in various research activities through which the farmers living in and around courtallam are benefited very much.

A broad outline of research activities carried out by the centre
Identification of alternate/supplemental feedstock for biogas production
  • Agricultural residues – paddy straw, bagasse, coir dust, banana stem, ground nut shell, vegetable market waste, Aloe vera peelings collected from aloe processing unit
  • Animal waste – human excreta, animal excreta of cow, goat, pig, donkey, poultry droppings and slaughter house waste
  • Aquatic plants – Water hyacinth, Pistia and Lemna
  • Xerophytic palnts – Euphorbia, Opuntia and Cereus
  • Tropical plants – Lantana camara, Parthenium, Ipomea and oil cake of Jatropha curcas
  • Industrial effluents – paper mill sludge, dairy industrial effluent, sugar mill effluent
Uses of digested slurry coming out of biogas plant
  • Fish rearing
  • Animal feed supplement
  • As manure for crop cultivation
  • Vermicompost preparation
Preparation of organic manure through composting process
  • Dry leaves falling from trees
  • Paper waste, paper cups, question paper covers
  • Beedi leaf waste
  • Peelings of Aloe vera
  • Water hyacinth plants
Integrated nutrient management study
  • Effect of organic manure with commercial fertilizer application was carried out at farmer’s site in many villages on the cultivation of onion, chilly, raddish, tapioca, brinjal, tomato and bhendi
Radish cultivation using Biogas slurry (or) Effluent
Research work from Lab to Land
Microbial studies
  • Isolation and identification of aerobic and anaerobic (cellulolytic and methanogenic) microbes
  • Isolation of phosphate solubilising bacteria from the rhizosphere soil and its mass probagation using hydroxyl apatite medium
  • Antimicrobial activity of various plant extracts
  • Study on dairy microorganisms
  • Biochemical and microbiological aspects of courtallam water
Study on soil environment
  • The biochemical analyses of soil (pH, EC, organic carbon, nitrogen, phosphorous, potassium and sodium) and microbial analyses of soil (bacteria, fungi and actinomycetes) are being carried out
Students visit from other colleges
Degradation process of Dry leaves collected at college campus
Extension work
  • Training programme on the construction of biogas plant was conducted to masons. Both theoretical and practical classes were taken
  • Training given to potters in making improved Chula (TNAU – single pot, double pot, noon-meal Chula and udayaraj model)
  • Installation of improved Chula in many villages (Thavanai, Karkudi, Oormenialagiyan and Kulayaneri)
  • Construction of various models of biogas plants in many villages. Recently a 6 cu. m. solid state biogas plant was constructed at Aum Pranav Ashram. The gas produced from this plant helps to replace 6 LPG cylinders per month.
  • Monitoring the functional status of biogas plants and repairing of sick units
  • Awareness programme is being conducted every year for rural women and farmers on biogas technology, organic manure preparation, vermicompost technology and mushroom cultivation
  • g. A 9 cu. m. horizontal flow biogas plant was constructed in a municipal school at Tenkasi. The gas generated using vegetable market waste fed in this plant was used to cook noon meal for 70 children.
  • h. Competitions and seminars are conducted for the students to create awareness about Renewable Energy technology and gadgets in various districts
Bananastem waste for Biomethanation
Training given to selfhelp Groups
