Abstract:

The investigation was under taken during kharif and rabi season 2017-18 at Shaheed Gundadhur College of Agriculture and Research Station, Jagdalpur (Chhattisgarh). The pot experiment, during kharif season with transplanted rice, was laid out under Completely Randomized Design (CRD) with three replications and 11 treatments comprised with keeping one treatment of application of all nutrients (N, P, K, S, Ca, Mg, Cu, Zn, B, and Mo) in optimum level and other treatments were formulated by sequentially omitting each nutrient from all nutrients applied. The result revealed that the omission of nutrients N, P and S significantly reduced the plant height, tillers pot-1, effective tillers pot-1, filled grains panicle-1, grain and straw yield of rice and uptake of N, P, K, S, Ca, Mg, Cu, Zn, Mn, Fe and B by rice in comparison to treatment that received all nutrients. The highest grain yield 66.4 g pot-1 were recorded under the treatment receiving all the nutrients and that of lowest grain yields 34.8 pot-1 were recorded under omission of N, followed by omission of P (42.5 pot-1) and S (56.3 pot-1) nutrients. Based on these results of kharif season, the limiting nutrients were identified as N, P, and S. These nutrients were applied at the rate of 150 kg N, 100 kg P2O5, 100 kg K2O, 45 kg S ha-1. This dose, known as SSNM dose was tested at farmers field, from where the bulk soils were collected for pot experiments, with wheat crop during rabi season 2017-18. SSNM dose resulted in higher grain yield of wheat in comparison to that of farmer’s fertilizer doses at the rate of 80 kg N: 50 kg P2O5: 0 kg K2O ha-1. About 13.3 % increase in the wheat grain yield were recorded due to SSNM dose based on identified yield limiting nutrients over farmer's practice dose.
