Abstract: Integrated Nutrient Management (INM) approach is need of the hour which involves efficient and judicious use of all the major components of plant nutrient sources viz. chemical fertilizer in conjunction with manures and biofertilizers for sustaining soil fertility, health and productivity in intensive rice- mustard cropping systems. A field experiment was conducted in the Krishi Vigyan Kendra, Jamui, Bihar during 2014-15 and 2015-16 with rice (cv. Rajendra mahsoori-1) as kharif crop and mustard (cv. Pusa bold) as a rabi crop to investigate the influence of integrated nutrient management on soil health and yield of crops in rice-mustard cropping system. The experiment comprised of nine treatments, each replicated five times with a plot size of 20 m2 in randomized block design. Soil samples were collected and analyzed for physical, chemical and biological properties before and after the crop harvest. Based on two years pooled data, the highest grain yield (q/ha) in rice and (q/ha) in mustard. The lowest grain yield was recorded in T9 treatment. The treatments received organic amendments recorded higher microbial biomass carbon, basal soil respiration and fluorescein diacetate hydrolyzing activity over the treatments received chemical fertilizers in both rice and maize crop. So sound agronomic and environmentally acceptable integrated nutrient management practices are essential for sustaining higher yield and good soil health in rice – mustard cropping system in Bihar.
