Abstract:
A pot experiment was carried out to determine the impact of application of antitranspirants, viz. Kaolin and Green Miracleon growth, yield and nutrient content of rice (HUR-105) under both submerged and water-stressed condition grown in an Inceptisol of Varanasi, Uttar Pradesh. The Kaolin (0%, 4%, 6%, and 8%) and Green Miracle (0.0%, 0.15%, 0.3%, and 0.6%) water suspension / solution respectively, were sprayed twice viz.during vegetative-stage and panicle initiation stage. The plant parameters including plant height, number of leaves, tillers numberwere taken at tillering, panicle initiation and grain filling stages. The nutrient concentration including N, P, K and S in grain and straw were analyzed. Results indicated that antitranspirants treatments have positive effect on the plant growth parameters and dry matter production of rice. Plants treated with long chain fatty alcohol (Green Miracle) and kaolinite (Kaolin) produced higher i.e. 6.7% to 19.3% dry matter than untreated (control) plants.
