Abstract
A field experiment was conducted to evaluate the effect of integrated nutrient management on soil quality and its management. It was carried out at Research cum Instructional Farm, I.G.K.V., Raipur (C.G.) during kharif 2012, with the objective to study the response of integrated nutrient management on short grain aromatic rice varieties for optimization of yield and quality. The experiment was laid out in split plot design with three replications having four varieties namely (V 1 ) Dubraj, (V 2 ) Badshah Bhog, (V 3 ) Vishnu Bhog and (V 4 ) Bisni in main plot and six nutrient management treatments i.e. (N 1 ) 60:40:30 Kg N:P2O5:K2O ha -1 (Inorganic), (N 2 ) 80:50:40 Kg N:P 2 O 5 :K 2 O ha -1 (Inorganic), (N 3 ) 60:40:30 Kg N:P 2 O 5 :K 2 O ha -1 (50%Inorganic+50%Organic), (N 4 ) 80:50:40 Kg N: P 2 O 5 : K 2 O ha -1 (50%Inorganic+50% Organic), (N 5 ) 60:30:60 Kg N: P 2 O 5 : K 2 O ha -1 (Organic-FYM) and (N 6 ) 80:40:80 Kg N:P 2 O 5 :K2O ha -1 (Organic-FYM) in sub-plots. The result indicated that the treatments significantly influenced the available NPK status of soil. The application of 80:40:80 kg N:P 2 O 5 :K 2 O ha -1 (Organic-FYM) obtained the highest gain of available nitrogen, phosphorus and potassium in soil. While in case of available nitrogen in soil, application of 80:40:80 kg N:P 2 O 5 :K 2 O ha -1 (Organic-FYM) found at par with the application of 80:50:40 kg N:P 2 O 5 :K 2 O ha -1 (50%Inorganic+50%Organic). The application of 60:40:30 kg N:P 2 O 5 :K 2 O ha -1 (Inorganic) had the lowest gain of available nitrogen, phosphorus and potassium in soil. In general, organic manures improve the physico- chemical properties of the soil and improve the microbial activity which resulted in maintaining the soil fertility. Chemical fertilizers applications reduce the post harvest soil nutrients as compared to organic manures application. The building up status of available nitrogen in soil recorded under the application of 80:50:40 kg N:P 2 O 5 :K 2 O ha -1 (Organic-FYM). This might be due to application of FYM. FYM added soils gain higher organic residue, this resulted in higher retention of nutrients. In general organic manures reduce leaching and volatilization losses of nitrogen. Organic manures are known to reduce phosphorus and potassium fixation. Keywords: Integrated Nutrient Management, Soil Quality, Organic Manures and Inorganic Manures
