Effect of integrated nutrient management on production potential and quality of mungbean under custard apple based agri-horticultural system

An experiment was conducted during kharif seasons of 2009 and 2010 to find out the effect of integrated nutrient management on crop growth, yield attributes, yield and quality of mungbean under custard apple based agri-horticultural system. Increasing the fertility level significantly increased the growth, yield attributes, yield, protein content and nutrient uptake by mungbean. Application of RDF+FYM 5 t/ha registered maximum growth attributes, number of nodules, nodules dry weight, yield attributes and produced 8.42 and 5.1 per cent higher seed yield (1060.57 kg/ ha) over RDF (978.14 kg/ha), and RDF+FYM 2.5 t/ha (1009.57 kg/ha), respectively. Fertility level RDF+FYM 5 t/ha similarly registered highest protein content (22.34%), protein yield (238.37 kg/ ha) and nutrient uptake (85.65:9.47:75.33 :: N:P:K kg/ha). Mungbean produces maximum response with biofertilizer + Mo 1.0 +Co 1.0 kg/ha in respect to growth, yield attributes, nodule number, nodule weight and 41.24 per cent higher grain yield over control (841.33 kg/ha). Protein content (24.21%), protein yield (287.79 kg/ha) and nutrient uptake (100.47:11.34:87.62::N:P:K kg/ha) were also recorded maximum with biofertilizer + Mo 1.0 + Co 1.0 kg/ha.
