Abstract:

The effect of integrated nutrient management (INM) on yields and active pools of soil organic carbon (SOC) under groundnut-wheat cropping sequence of a Haplustepts soil was studied in a long term field experiment initiated since 1999 at Junagadh, Gujarat. Effect on varying doses of N, NP, NPK, NPK with FYM, Zn, S and Rhizobium on yields and active pools of SOC viz., soil microbial biomass carbon (SMBC), soil microbial biomass nitrogen (SMBN), soil microbial biomass phosphorus (SMBP), water soluble carbon (WSC), water soluble carbohydrate (WS-CHO) and dehydrogenase activity (DHA) after 16 year of groundnut-wheat crop sequence was studied. The result revealed that application of 50 % NPK + FYM @ 10 t ha-1 to groundnut and 100 % NPK to wheat significantly increased the groundnut yield and wheat yield. The highest and significant increase active pools of soil organic carbon was also observed under combine application of 50% NPK + FYM @ 10 t ha-1 to groundnut and 100 % NPK to wheat. These results indicate that long-term integrated use of FYM with chemical fertilizers or use of FYM alone exerted significant effect on the active pools of soil organic carbon.
