Abstract:
Integrated nutrient supply of inorganic and organic sources is of great importance for maintenance of soil health and crop productivity in intensive rice - maize 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 <em>kharif</em> crop and maize (Shakatiman-4 hybrid) as a <em>rabi</em> crop to investigate the influence of integrated nutrient management on soil health and yield of crops in rice-maize cropping system. The experiment comprised of nine treatments, each replicated five times with a plot size of 20 m<sup>2 </sup>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<em>, </em>the highest grain yield (49.2 q/ha) in rice and (53.9 q/ha) in maize. The lowest grain yield was recorded in T<sub>9</sub> 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. The T<sub>8</sub> treatment comprising 100 % NPK+ Vermicompost @ 2 t/ha+ PSB @ 8 kg/ha (Soil application), both in rice and maize recommended for higher productivity and good soil health in rice – maize cropping system in Bihar.
