Performance of Blackgram (Vigna mungo L.) under Integrated Nutrient Management (INM) in a legume based cropping system for the inceptisols of NEPZ

A field experiment was conducted during kharif seasons of 1998 and 1999 at Allahabad Agricultural Institute - Deemed University, Allahabad to study the effect of fertilizer levels, organic manures and biofertilizer along with organic spray on the yield of blackgram under blackgram - wheat - greengram system. Plant dry weight values showed no significant difference between one hundred per cent and 33% RDF levels. Similarly, some yield parameters showed same trends. Organic manure application showed increased yield over the control. Biofertilizer and organic spray helped in significant increase of the dry matter production and test weight. The interaction of these components registered better performance, thus inferring the importance of integrated nutrient supply system.
