Three fertility gradient stripes were created in Inceptisols of Odisha by applying no fertilizer, recommended dose of fertilizer (RDF) and double the RDF and paddy was grown during kharif, 2013. These three stripes were sub-divided into 24 sub-plots and black gram was grown with different graded doses of fertilizers and manure during rabi, 2013-14. Initial and post-harvest soil nutrient status, nutrient uptake, nutrient requirement, soil efficiency, fertilizer efficiency and yield data were recorded. The highest yield (12.09 q ha-1) was achieved with 30 : 50 : 50 (N : P2O5 : K2O). On the basis of these data, fertilizer prescription equations were formulated for targeted yield of black gram in Inceptisols of Odisha.

Abstract


Three fertility gradient stripes were created in Inceptisols of Odisha by applying no fertilizer, recommended dose of fertilizer (RDF) and double the RDF and paddy was grown during kharif, 2013. These three stripes were sub-divided into 24 sub-plots and black gram was grown with different graded doses of fertilizers and manure during rabi, 2013-14. Initial and post-harvest soil nutrient status, nutrient uptake, nutrient requirement, soil efficiency, fertilizer efficiency and yield data were recorded. The highest yield (12.09 q ha-1) was achieved with 30 : 50 : 50 (N : P2O5 : K2O). On the basis of these data, fertilizer prescription equations were formulated for targeted yield of black gram in Inceptisols of Odisha.
