Through On Farm Testing Krishi Vigyan Kendra does comparative studies in farmers’ fields to come to conclusion which of the technologies tested is more suitable to the resources available in the district & is cost effective.

On Farm Testing is aimed at testing the proven technologies evolved at Research Stations on farmers’ field with their farming system perspective in view under their management and their active participation so as to convince them the relevance and viability of the new technology. This OFT was conducted on Contingent Plan of Rice cropping for Periyar Vaigai Command Area of Madurai east block of Madurai District. It is evident that the practice of green manuring has been widely adopted by rice farmers, although its value for increasing rice yield by supplying nutrients and maintaining soil productivity is well established. In this context, this technology, Rice cum green manure seeding has come as an alternative practice to improve the soil fertility and to increase rice production.
