Effect of moong straw on soil propertiesunder INM in long term rice,wheat cropping system in a Mollisol

摘要

A field experiment was conducted at Norman E. Borlauge Crop Research Centre, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar during 2008-09 to study the effect of moong straw on soil properties under INM in long term rice-wheatcropping system. Twelve treatments were replicated twice in split plot design with 12 main and 2 sub plots. Bulk density, pH, electrical conductivity, organic carbon, available nitrogen, phosphorus, potassium and cation exchange capacity of soil were determined. The treatments receiving 100% N or NPK as well as where 50% N was applied through moong straw were found better than all other treatments and moong straw proved the best among organic sources of N studied in respect of its effect on nutrient status in soil and other soil properties.
