Abstract
Two pot experiment was conducted at Instructional Farm of Krishi Vigyan Kendra, Raigarh (C.G.) during Kharif season, 2015 for identification of yield limiting nutrients through crop response in Vertisol and Inceptisol of Raigarh district of Chhattisgarh with rice (MTU-1010) as test crop. The experiments were laid out in Completely Randomized Design with 11 treatments and 3 replications. Yield attributing characters viz. effective tillers, filled grains panicle-1 and grain and straw yields of rice in both soil types were significantly influenced by nutrient omission treatments. In Vertisol omission of N, P, S and Zn resulted in significant reductions in yield attributing parameters and grain and straw yields. Highest grain and straw yields (28.69 and 31.35 g pot-1, respectively) were recorded with the treatment receiving all the nutrients whereas the lowest with omission of N (18.46 and 21.01 g pot-1, respectively) followed by P, S and Zn omission. Omission of N reduced the grain yield by 35.65% while P omission reduced grain yield by 28.89% over the treatment receiving all nutrients. Per cent reduction of grain yield under different nutrient omitted pots followed the order N > P > S >Zn. In Inceptisol, omission of N, P and S reduced the yield attributing parameters and grain and straw yields significantly over the treatment receiving all the nutrients (grain and straw yield being 30.57 and 32.58 g pot-1, respectively). Omission of N, P and S reduced the grain yield by 47.64%, 40.82% and 19.51%, respectively. Nutrient uptake by rice was significantly reduced with omission of N, P, S and Zn in Vertisol and with omission of N, P and S in Inceptisol. On the basis of per cent grain yield reduction, the limiting nutrients found in the order of N > P > S > Zn in Vertisol and N > P > S in Inceptisol.
