Dissemination of Nutrient Expert® Fertilizer Decision Support Tool for Wheat and Maize in Eastern India

A total of 24 KVKs across three states of this zone have conducted the NE® trial supported by IPNI. These KVKs are of Bihar, Jharkhand, and West Bengal. The common experimental design for all implementing KVKs was:- (i) Group-I: Farmer’s practice; (ii) Group-II: Application of recommended dose of fertilizers; and (iii) Group-III: Application of fertilizer doses as per the NE® tools developed by IPNI. The trials were conducted on wheat (by 22 KVKs), though few trials were also carried out on maize (2 KVKs) during last Rabi season pre-dominantly under Rice-Wheat production system. The unique nature of this trial was that the individual farmer was provided with all the three technological options for his/ her plot(s). The data were collected for their further analysis in order of extension of the NE® for wheat/maize to be recommended for this zone.
