tailieunhanh - Effect of nutrient management and crop establishment methods of rice on biological properties of soil

A field experiment was conducted at Research Farm, Dr. RPCAU Pusa, Bihar during kharif 2018 on calcareous sandy loam soil, having pH , medium in soil organic carbon content ( %), EC dSm-1 , available nitrogen (195 kg/ha), available phosphorus ( kg/ha) and available potassium (134 kg/ha). Experiment was laid-out in split-plot designand replicated thrice. Main-plot included three crop establishment methods, viz. dry direct-seeded rice (DSR-dry), wet direct-seeded rice (DSR-wet) and puddled transplanted rice (TR). In sub-plots, five nutrient management methods T1- 100% STCR Based Dose of Fertilizer + ZnSO4 @ 25 kg ha-1 (DF), T2-75% DF + 25% STCR based Recommended Dose of Nitrogen (RDN) through Vermicompost, T3-100% STCR based RDN through Vermicompost, T4- 100% DF + 50% STCR based RDN through Vermicompost and T5- 50% DF + 25% STCR based RDN throughVermicompost. The post-harvest soil was analysed to evaluate the effect of different nutrient management methods on soil microbial biomass Carbon (SMBC), soil microbial biomass Nitrogen(SMBN), Microbial population and Dehydrogenase Enzyme (DH) activity under the three different establishment methods. | Effect of nutrient management and crop establishment methods of rice on biological properties of soil
