Response of rice to nutrient omission in soils of Chhattisgarh plain
Author(s): Tirath Das Sahu and Khema Das Mahant
Abstract: Experiments were conducted at Instructional Farm in the Department of Soil Science and Agricultural Chemistry, College of Agriculture, I.G.K.V., Raipur, Chhattisgarh in Completely Randomized Design with two factors (Treatments and soils) to study the response of rice to nutrient omission and identify yield limiting nutrients. Grain and straw yields of rice were significantly reduced with the omission of N, P, Zn, S and B in all the soils. Yield reductions were more pronounced with omission of N (68.7% and 68.4%, respectively) followed by P, Zn, S and B. Large reductions in nutrient uptake by rice were observed with N, P, Zn, S and B omission. Nitrogen was found to be the most yield limiting nutrient next to phosphorus. Other nutrient elements which were found to be limiting includes zinc, sulphur and boron in almost all the soils of Chhattisgarh plain. Extents of limitations were more in Kanhar (Jora) soil followed by Matasi (Banrasi) and Dorsa (Darba) soil.
