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.

Interpretive Summary

The present study was conducted in the eastern Indian states of Bihar, Jharkhand, and West Bengal in collaboration with the Indian Council of Agricultural Research (ICAR) - Agricultural Technology Application Research Institute. The project validates and disseminates the use of Nutrient Expert® (NE) Wheat at farmers' fields through Krishi Vigyan Kendra, the Extension system and last-mile delivery mechanism of ICAR.

The study was conducted in the eastern Indian states of Bihar, Jharkhand and West Bengal in collaboration with ICAR - Agricultural Technology Application Research Institute. The project validates and disseminates the Nutrient Expert® (NE) for wheat in farmers' fields through Krishi Vigyan Kendra, the Extension system and "last mile delivery" mechanism of ICAR.

Nutrient Expert® (NE) dissemination trials for hybrid maize and wheat were conducted among the farmers of three agriculturally resourceful eastern Indian states comprising of Bihar, Jharkhand and West Bengal. There were 12 districts from Jharkhand, 9 districts from Bihar, and 3 districts from West Bengal selected during the Rabi season of 2013-14 in collaboration with 24 Krishi Vigyan Kendras (Knowledge Dissemination Center for Farmers) for NE dissemination.
