Modulating Effect of PGRs on Growth and Biochemical Traits in Rice (Oryza sativa L.) under Salt Stress

An investigation was conducted to study the effect of plant growth regulators on rice (variety Sarju-52) grown under sodic conditions, during kharifseason 2018 at students’ instructional farm ANDUA&T, Kumarganj, Ayodhya. The experiment laid out in randomized block design with nine treatments and three replications, different concentrations modes application (PGRs). PGRs were applied as follows- seed priming GA3 @25 ppm & 50 SA @ 10 25 ppm, foliar SA, each 100 200 30 (DAT), along untreated control. Seed done for 12 hours PGRs. Thirty five days old seedlings transplanted field from nursery. Observations recorded various parameters such height, number tillers, dry biomass/hill, relative water content biochemical like chlorophyll, TSS, 30, 60 90 DAT maturity (harvesting stage). Both positively influenced characters, chlorophyll content, total soluble sugars. Moreover, spray @200 found have a more pronounced improving yield variety studied, among all treatments, conditions. It can be concluded that is effective salt stress.
