Abstract:

The investigation was carried out at Shaheed Gundadhur College of Agriculture and Research Station, Jagdalpur with the objectives to identify the specific yield limiting nutrients through response of rice to nutrient omission in pot culture during kharif season, 2017 and to demonstrate the optimum use of identified limiting nutrients at field level in wheat crop during rabi season 2017-18. The soil was a sandy clay loam, had a slightly acidic soil reaction (pH 6.2), normal electrical conductivity, medium organic C and available K, low available N, P, and S, high available Ca, Mg, Fe, Mn and Cu and marginal available Zn and B. The experiment was laid out under completely randomized design with 3 replications and 11 treatments, formulated by keeping one treatment with application of all nutrients in optimum level and others by sequentially omitting each nutrient. Omission of N and P nutrients significantly reduced the different growth, yield and nutrients uptake parameters of rice in comparison to all nutrients. The maximum grain yield of 67.1 g pot-1 was recorded, in all nutrients pot and 40.8 % reduction in grain yield of rice, from the maximum yield, was recorded in N omitted pots, followed by 23.7 % reduction in P omitted pots and omission of other nutrients didn’t reduce the grain yield significantly indicating that only N and P were yield limiting nutrients. In field verification during rabi season, 17.8 % increase in wheat grain yield and 20.9 % increase in net return was recorded, due to optimum dose of identified yield limiting nutrients over farmer's practice dose.
