Effect of Integrated Nutrient Management on Soil Physico- Chemical Properties of Rajmash in Acid Soil of Nagaland

Abstract

A field experiment at demonstration field of Krishi Vigyan Kendra (KVK) at Porba village, Phek District, Nagaland was conducted during the kharif season of 2012 and 2013 to study the effect of integrated nutrient management on soil physico-chemical properties of a rajmash in acid soil of Nagaland. The field experiment was laid out in randomized block design (RBD) with three replications and 18 treatments. The integrated treatments involving both organic and inorganic fertilizer influenced favourably the fertility status of the soil as compared to the control. Both bulk density and particle was found to decrease in all the treatments in both the experimental year over the initial value. There was an increase in the pH of the soil at the end of the cropping sequence from the initial value. Organic carbon content, EC and CEC of the soil were found to be increased in all the treatments over the initial value and the highest value was recorded in treatments where 5 ton FYM + Biofertilizer + Lime+ 50% NPK were applied.
