Abstract
The present investigation was carried out rabi season 2005-06 at instructional farm under All India Coordinated Project on Cropping System Research, main centre, Indira Gandhi Agriculture University, Raipur (C.G.). The experiment was laid out in randomized block design, replicated thrice with twelve treatments. Inorganic and integration of inorganic with organic (FYM, RS, GM as a N source) sources were applied in kharif season and only balanced inorganic fertilizer combinations in graded doses were applied during rabi season.
The result revealed that application of organic along with inorganic fertilizer combination during kharif and rabi were found superior effect by improving physical properties of soil (bulk density, gravimetric moisture content, infiltration rate, cumulative infiltration hydraulic conductivity, soil aggregation and mean weight diameter) as compared to only inorganic fertilizer applied both the crops.
The result further revealed that before sowing and after harvest of wheat no significant changes was observed with respect to pH and electrical conductivity of soil. Application of organics (FYM, RS and GM) with inorganic fertilizer treatment in rice along with 100% RDF in wheat gave higher soil organic carbon, available nitrogen and phosphorus content of soil as compared to control. However, depletion of native soil K were found in all the treatment except 50% RDF + 50% N (FYM) (Kh) + 100% RDF (Rb) treated plot.
The result revealed that wheat grain yield; yield attributing parameters and major nutrient uptake was found superior in different organic and inorganic treatment combinations as compared to 50% or 75% RDF to both the crop.
