Response of mungbean to fertility and lime levels under soil acidity in an alley cropping system of Vindhyan Region, India

Abstract

A field experiment was conducted to find out the management strategy with fertility and lime levels in an acidic soil, and its response to mungbean production. The experiment was laid out in factorial randomized block design with three replications, assigned 16 treatments combinations consisting four levels of recommended dose of fertilizers (RDF) i.e. (0, 75%, 100%, 125% RDF) and lime (0, 100, 200 and 300 kg/ha), the RDF was 20:40:20 kg /ha (N2: P2O5: K2O). Results were obtained at critical difference (CD) values p=0.05 level. Among the treatments,significant improvement was recorded in 100% RDF on dry matter accumulation (g/plant) of root (9.121), leaf (1.573), stem (8.230), total dry matter/plant (14.37), number of trifoliate (13.03), Soil-Plant Analyses Development (SPAD) value (nmol/mg) of chlorophyll (49.09), yields kg/ha of grain (524), straw (1425) and biological (1949). Similarly, the application of 200 kg lime/ha was significantly increase in dry matter accumulation (g/plant) of root (9.041), leaf (1.559), stem (8.158), total dry matter/plant (14.25), number of trifoliate (12.41), SPAD value of chlorophyll (48.59), yields kg/ha of grain (520), straw (1419) and biological (1930). Hence, on the basis of conducted field experiment recommended @ 100% RDF and 200 kg lime/ha for better mungbean crop productivity in the vindhyan region, India.
