Abstract:

A missing nutrient pot experiment for assessment of yield limiting nutrients in soil 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 with three replications and 11 treatments comprised with keeping one treatment of all nutrients (N, P, K, S, Fe, Mn, Cu, Zn, B, and Mo) applied in optimum level and other treatments were formulated by sequentially omitting each nutrient from all nutrients treatment. The result revealed that the omission of nutrients N, P, Zn and B 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 90.6 g pot-1 were recorded under the treatment receiving all the nutrients and that of lowest grain yields 40.8 g pot-1 were recorded under omission of N, followed by omission of P (60.2 g pot-1) Zn (72.9 g pot-1) and B (78.4 g pot-1) nutrients. Based on these results of kharif season, the limiting nutrients were identified as N, P, Zn and B. These nutrients were applied at the rate of 150 kg N, 100 kg P2O5, 100 kg K2O, 7.5 kg Zn ha-1, and 3 kg B ha-1. This site specific nutrient dose was tested with wheat crop during rabi season 2017-18 at same farmers field, from where the bulk soils were collected for kharif pot experiment. Site specific nutrient dose based on identified yield limiting nutrients resulted about 14-17 percent increase in grain yield of wheat over farmer’s fertilizer dose at the rate of 80 kg N: 50 kg P2O5: 0 kg K2O ha-1.
