Nutrient omission: An plant nutrient deficiencies assessment technology of rice (Oryza sativa) in Inceptisols

Author(s): SP Singh, KK Paikra and Chanchala Rani Patel
Abstract: Experiment was conducted on rice (Oryza sativa) during Kharif, 2015 at Instructional Farm of Krishi Vigyan Kendra, Raigarh (C.G.) to investigate the yield limiting nutrients through crop response in Inceptisols with rice (MTU-1010) as test crop. The experiments were laid out in Completely Randomized Design (CRD) with 11 treatments and 3 replications. Yield attributing characters viz. effective tillers, filled grains panicle-1 and grain and straw yields of rice were significantly influenced by nutrient omission treatments. The 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 (16.01 and 30.57 g pot-1) were recorded with the treatment receiving all the nutrients whereas the lowest with omission of N (18.01 and 32.58 g pot-1) followed by P, S and Zn omission. The omission of N reduced the grain yield by 47.64% while P omission reduced grain yield by 40.82% over the treatment receiving all nutrients. Per cent reduction of grain yield under different nutrient omitted pots followed the order N > P > S >Zn. The omission of N, P and S reduced the yield attributing parameters and grain and straw yields significantly over the treatment receiving all the nutrients. Nutrient uptake by rice was significantly reduced with omission of N, P and S. On the basis of per cent grain yield reduction, the limiting nutrients found in the order of N > P > S.
