Abstract:
The present investigation was conducted for two consecutive years with objective to know the various integrated nutrient management and rice varieties on soil chemical properties. The present study comprised six integrated nutrient modules viz., F0 (control), F1 [RDF (120:60:60)], F2 (50% RDF + 50% N through vermicompost), F3 (75% RDF + 25% N through vermicompost), F4 (50% RDF + 50% N through FYM) and F5 (75% RDF + 25% N through FYM), two varieties (NDR-359 and Sarju-52) and plant geometry S1 (20cm × 20cm) and S2 (30cm × 30cm). The investigation revealed that the build up of neutral soil pH, reduction in EC and increasing OC were found in INM treatments in varieties and plant geometry as compared to sole inorganic fertilizer treatment (F1) and maximum reduction in pH was observed with the application of F2 (50% RDF + 50% N through vermicompost). Whereas, the maximum increase of organic carbon also recorded with the application of the treatment F2. Varieties and plant geometry did not build up of pH, EC and organic carbon. The higher availability of nutrients N, P and K in soil after harvest was recorded in all the INM treatments as compared to inorganic fertiliser application treatments and control. Whereas, the maximum availability of N, P and K after crop harvest were estimated under the treatment having F2 (50% RDF + 50% N through vermicompost), which was closely followed by F4 and F3. Therefore, the maximum availability N, P and K were found in variety NDR-359 under plant geometry S2 (30 cm × 30 cm) followed by Sarju-52and S1 (20 cm × 20 cm), respectively.
