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 : P 2 O 5 : K 2 O). On the basis of these data, fertilizer prescription equations were formulated for targeted yield of black gram in Inceptisols of Odisha.
