| dc.description.abstract | The present experiment “Effect of Conjoint Use of Organic and Inorganic Sources of Nutrient on Soil Properties, Yield and Nutrient Uptake in Rice Crop” was carried out during kharif season of 2020 at Norman E. Borlaug Crop Research Centre of the Govind Ballabh Pant University of Agriculture and Technology, Pantnagar. The experiment was laid in RBD and replicated three times with eleven treatments. The conjoint use of inorganic and organic fertilizer for short duration influenced significantly the soil properties and crop yield. The soil aggregate stability and bulk density ranges from 16.47 to 20.83% and 1.25 to 1.35 Mg m-3, respectively. Experiment findings indicated that the conjoint use of inorganic fertilizer with organic sources significantly influences aggregate stability and non-significantly influences the bulk density. Also, the soil pH and EC ranged from 7.09 to 7.45 and 0.297 to 0.338 dSm-1, respectively, indicated that the conjoint use of organic and inorganic sources significantly influence soil pH and EC. The content of organic carbon, available N, P and K improved significantly over the control. The content of organic carbon, available N, P and K ranged from 0.51 to 1.19%, 232.48 to 345.74 kg ha-1, 6.61 to 30.71 kg ha-1 and 151.33 to 208.85 kg ha-1, respectively. The soil carbon fractions i.e. C-frac1, C-frac2, C-frac3 and C-frac4 and soil organic carbon stock improved significantly in all treatments over the control and the treatment (T6), receiving 75% wheat residue + 25% RDF + Pusa decomposer resulted significantly higher carbon fractions and organic carbon stock values than others. The treatment (T10) having 100% RDF + FYM @ 5 t ha-1 + Zn + B was found best among all the treatments which improves the crop yield, nutrient use efficiencies, nutrient status of soil and maintain soil fertility level. It is concluded from this study that the conjoint use of inorganic fertilizer and organic sources significantly improves the soil physical and chemical properties, nutrient status, crop yield and nutrient use efficiencies for long term. | en_US |
