 ABSTRACT

A field experiment was conducted on rice during kharif season of 2015 using different doses of nitrogen, phosphorus, potassium as per recommended practices along with FYM @ 5tha-1, and micronutrients viz. boron and zinc using black gram as the test crop. All samples are processed and chemical analysis of plant and seed samples as well as protein content are done by using the standard protocol. The experiment was conducted using four levels of potassium viz., 0, 20, 40 and 60   kg ha-1, four levels of sulphur viz., 0, 10, 20 and 30   kg ha-1, three levels of phosphorus viz., 0, 20, 40 kg ha-1, nitrogen in a single dose @ 80 kg ha-1 and the residual effect of micronutrients from the previous crop using rice as the test crop. The results revealed that highest significant grain, straw and biological yield (8.43, 11.28 and 19.71 t ha-1 respectively) recorded when the crop received all the nutrients (N, P, K, S, B and Zn). Protein content ranged between 14.35 to 17.97%. Combined application of all the nutrients increased nutrient accumulation and uptake. Among the micro and secondary nutrients, deletion of B greatly affect the N, P and K uptake as compared to Zn and S. Balanced application of N, P and K with S, B and Zn recorded highest grain yield response.

Keywords: Rice, Balanced Nutrient Management, Yield, Uptake, Protein content.
