4. Problem/Challenge addressed:
Generally the farmers are collecting cow dung from cattle shed and stores in a heap for decomposition for atleast three months and applied in the field through broadcasting before last ploughing, Here a valuable resource from cattle shed i.e.urine is wasted or not properly utilized. More over the nutrients in the decomposed Farm Yard Manure is also goes as waste when it is broadcasted.
The increasing cost of chemical fertilizers poses serious threats to farmers that too the water soluble fertilizers costs very high. Continuous use of chemical fertilizers without addition of organic matter led to reduced productivity in long run,
These
problems were addressed by the innovation developed by Mr.V.Tamilarasan.
5. Description of Innovative practice/ Technology
Mr.V.Tamilarasan is an innovative progressive farmer is practicing Integrated Farming System in his farm. He is cultivating horticultural crops like Tuberose, Marigold, Vegetables, field crops like Paddy and Fodder cops. He is also having livestock components like Dairy and Goat, Production and utilization of Azolla and Vermicompost, Honey bee rearing and Fish rearing are the points of attraction in his farm. By adopting this IFS model and cropping he is becoming successful farmers of the locality and is very well established and known farmer of the village. He is now a source of inspiration for all the other farmers of the locality for improving their livelihood.
The principle behind his innovative technology is recycling and effective use of the wastes like cow dung and cow urine from the cattle shed. The cow dung and cow urine carefully collected from the cattle shed is filtered for residues, enriched with micro organisms by allowing for 12 hrs fermentation & sedimentation process. To facilitate this process he has constructed three consecutive tanks (cement works) and by series of process the cow dung and urine is converted into effective liquid manure.
Then the liquid manure is directly pumped to the tuberose field through drip and fertigation method and through PVC pipelines to paddy field to reduce the man power and cost of cultivation.The cost of the construction of this permanent sustainable liquid manure unit is higher around Rs.75,000.
6. Practical Utility
The digested materials and effective micro organisms in the liquid organic manure (i.e, cow dung and urine) helped the farmer to reduce the half of the cost of fertilizer application in the due course of one year time. Previously he was using water soluble fertilizer like urea 5 kg, 19:19:19 complex 5kg at 10 days interval through drip for an acre. Now he is using urea 5 kg, 19:19:19 complex 5 kg at 30 days interval only. Cost of fertilizer dose was @Rs.775 per time i.e, Rs.2,325/month for fertigation previously but now it is only Rs.775/month for fertigation. He noticed and revealed that in the period of one year there was a good improvement in soil characters, beneficial micro organisms and earthworm population in the soil. There was reduction in Nematode infestation and disease like root rot incidence. Through sprinkler irrigation the thrips population in the tuberose was also minimized. More over it has helped the crops to grow healthy and withstand the hot weather periods.

7. Source of Information
Mr.V.Tamilarasan was first inspired by the speech of Mr.Nammalvar, Environmental Activist, Philosopher and Organic farming expert who spreads Ecological farming & Organic farming in Tamil Nadu in a bigger way. Afterwards Mr.V.Tamilarasan came to our KVK to gather more information about the Integrated Farming System and effective recycling of cattle wastes. The Scientists in the KVK has explained about the IFS model through trainings and demonstration in the KVK farm. Then he came up with the model of cost effective long term sustainable liquid manure production unit from cattle resource (i.e, cow dung and cow urine) and after slight modification suggested by our KVK he has established this unit. Now this model is working very well and the same model is being functioning at instructional farm of KVK, Ariyalur to showcase the effectiveness of this technology to larger number of farmers.
Initially, he started production of liquid manure unit in a small 200 litres capacity barrel tank by adding cow dung 10 kg, cow urine 25 lit, 2kgs of Jaggery and then adding water to the remaining portion. By seeing the uses of the liquid manure, he shifted the production to a big cement tank capacity of 500 litres. Again after increasing the cattle population to 11 numbers now he has established a liquid manure recycling cement tank capacity of 9900 litres (Tank Size 10 x 9 x 6 cubic feet).
8. Details of scientific verification
ICAR-KVK, Ariyalur is rendering technical guidance to Mr.V.Tamilarasan since he started Integrated farm development and especially in construction of liquid manure production unit and its usage to different crops, we are recording the earthworm population of the soil from July 2016 to till date and it is depicted in the following figure.
The farmer was advised to reduce the periodicity of chemical fertilizers from three times per month to only one time per month. At the same time, it was observed that the yield increase was noticed sizeably. Hence this is evident that the microbial activity is also increased to make the nutrients available to plants.
9. Funding Support
He has availed the funding support given by Fedaral Bank and availed subsidies from Department of Horticulture, Ariyalur District to micro irrigation structures and erection of shadenets. The details are as follows :
| S.No | Year | Name of the Donar/Lender | Amount(Rs.) | Subsidy amount | Loan Repayment |
| 1 | 2016 | Fedaral Bank, Thanjavur branch | 20 lakhs | — | 30% completed Repayment period – 7years |
| 2 | 2016 | Department of Horticulture, Ariyalur | 2.5 lakhs – Drip Irrigation | 2 lakhs (75%) | — |
