Abstract:

The field experiment was conducted during kharif season of 2016-17 and 2017-18 to find the influence of potassium fertilization on different growth and yield parameters of rice along with soil potassium pool. The experiment was laid out in Randomized Block Design with treatments comprised of different doses of potassium viz. 15, 30, 45, 60, 90, 120 kg/ha and a control plot without any fertilizer and it was replicated thrice. The experiment revealed that the plant growth parameters viz. plant height, number of active tillers per plant, test weight and yield were significantly increased with application of potassium fertilizer. With application of potassium fertilizer, plant parameters such as plant height, no of active tillers, test weight and yield of rice increased significantly. Pooled data of both the years suggested that, water soluble, exchangeable, available and HNO3 soluble potassium increased at all three stages, as fertilizer dose increased. The exchangeable potassium in control plot showed a decreasing trend with time.
