Co-fertilization of Silicon and Phosphorus Influences the Dry Matter Accumulation, Grain Yield, Nutrient Uptake, and Nutrient-Use Efficiencies of Aerobic Rice

Rice is known to be a nutrient exhaustive crop and the application of silicon (Si) has been reported for better utilization plant nutrients from soil. Hence, response phosphorus (P) could enhanced by co-fertilization Si P. The present study evaluates dry matter accumulation, grain yield, uptake, nutrient-use efficiency P in aerobic rice. Therefore, field experiment was conducted at ICAR-Indian Agricultural Research Institute, New Delhi, India factorial randomized block design, treatments comprised four levels (0, 40, 80, 120 kg ha–1) 30, 60, 90 P2O5 application. results revealed significant effect on uptake accumulation yield rice significantly higher with combination ha–1 closely followed 80 60 ha–1. rate increase due different doses ranged between 7.6 25.6 % over control. A strong positive relationship observed concentrations uptakes nutrients, barring zinc. Application concentration Si, nitrogen, P, potassium 25, 16.5, 47, 25 %, respectively, Overall, addition management productivity use
