Nutrient Expert: An ICT Tool of Agricultural Institution for Economic Development of Maize Growing Farmers in Jharkhand

Background: Nutrient expert is a computer based software for site specific nutrient management which advocates location specific requisite quantities of nutrients application in crops to achieve targeted yield by narrowing down the difference between actual yield and potential yield. The current study aimed to study efficiency of nutrient expert over other fertilizer recommendations on maize varieties.
Methods: An experiment was conducted to test six maize varieties against state fertilizer recommendation, nutrient expert based fertilizer recommendation and farmers’ fertilizer practice during Kharif season of 2017. The nutrient expert software was used to calculate dose of nutrient expert for targeted yield of 8 t/ha.
Result: The result indicated significant improvement by nutrient expert based fertilizer recommendation for grain yield, stover yield, net return and nutrient uptake of nitrogen, phosphorus and potassium in grain and stover of maize. Among maize varieties, CMH-08-350 recorded significantly higher grain yield, stover yield, net return and nutrient uptake of maize than PMH-3, CMH-08-287, PMH-1 and HQPM-1.
