Abstract
The field experiment entitled “Productivity and Quality Assessment of Basmati Rice Under Organic and Conventional Nutrient Management” was conducted in kharif season, 2016 and 2017 at G. B. Pant University of Agriculture and Technology, Pantnagar. The experiment was laid out in split plot design with two modes of production (organic and conventional). This study involved the simultaneous characterization of soil chemical properties, agronomical parameters attributing yield, biochemical parameters, quality parameters and nutrient uptake in organic and conventional mode of production. There was no significant effect of nutrients system on soil pH in the practices, Available phosphorus, potassium, ammonical nitrogen and nitrate content were higher for conventionally managed soil. Plant height significantly affected by source of organic nutrients i.e. higher in the organically managed system. There were no effects of nutrient supply systems on the number of productive tillers; they were almost same in both the practices. However, the leaf area index was significantly affected by the nutrient supply system. During both the years the leaf area index was higher in the inorganic source of nutrient system. Moreover, dry matter production, biological yield, total yield were higher in rice plant under inorganic nutrient management system. Harvest index of organic rice was more as compared to the conventionally grown rice. Amongst grain quality parameter, hardness, true density and percent porosity were higher in rice grains under conventional nutrient supply. Inorganic rice had better milling quality but cooking quality was found better in organic rice as evident from higher elongation ratio and swelling rate. The organically grown rice was found to be tastier in comparison to inorganically grown rice as organic sample scored higher for all the parameters of sensory. The quality of protein was better in organically managed rice. Total ash, crude fiber and iron element were found higher in organically managed rice. Iron was found to be significantly higher in organic rice (1.32 mg/100 g). The nutritional analysis revealed that organic crops had higher level of nutrients.
