Assessing the Impact of Co-fertilization of Silicon with Macronutrient Fertilizers on Yield, Nutrient Uptake, use Efficiency and Grain Quality of Rice in Sandy Clay Loam Soil

This study wanted to clarify the impact of silicon (Si) fertilization on nutrient uptake, use efficiency, yield and quality rice detect rate mode application Si fertilizer in deficient soil. The field experiment was conducted with ten treatment combinationsof100% NPK,100% NPK + potassium silicate (PS)@ 0.25%,0.50% 1.0% Foliar spray (FS) at tillering stage,100% PS@ 0.25% ,0.50% 1.0%FS panicle initiation stages,100% 50,100 150 kg ha-1soil (SA). Application 50 ha-1 through PS recorded highest grain (6183 ha-1) straw (6740 yield, higher uptake macronutrients (NP&K) it par foliar 1% sprayed stage. Silicon increased linearly levels maximum Si. efficiency compared soil application. Rice viz., protein, amylose carbohydrate were significantly influenced by addition. results proved that both sandy clay loam could enhance means improving efficiency.
