 ABSTRACT

A field experiment was conducted during season of February – April 2013 on clay soil at Experimental Farm, Annamalai University, to evaluate the post harvest soil available nutrients, nutrient uptake and economics as influenced by integrated nutrient management in irrigated greengram. The field experiment was conducted with recommended dose of fertilizer along with rhizobium and phosphobacteria (seed inoculation) @ 600 g ha-1 with foliar application of DAP @ 2% and NAA @ 40 ppm ha-1 and combined with salicylic acid @ 100 ppm ha-1 at 30 and
45 DAS. Integrated nutrient management not only increased the yield of greengram but also increased the nutrient uptake besides improving the physico-chemical and biological properties of soil which provide better soil environment for growth. The N, P and K uptake in system was higher when the crop was given under above said treatment combinations. Use of biofertilizer source helped in maintaining soil fertility in terms of available nutrients.

Key words: Greengram, Biofertilizer, Growth regulator, Nutrient uptake, Foliar nutrition and Economics.
