Abstract
Growth regulators is a chemical compound, which is either synthesized by the plants or exogenously applied. It affects the growth and metabolic rate thus affecting the yield and quality ofcrop. In this investigation, the Basmati rice plants were foliar sprayed with growth regulators (IAA, Kinetin, CCC, SADH and Ascorbic Acid) at tillering and before anthesis stage. Results showed a conspicuous increase in yield and quality traits in treated plants. The yield attributing traits like grain weight per plant,straw weight/plant, 1000 grain weight/test weight and Harvest Index (HI) was improved by the treatment of IAA. The quality trait viz. Grain Starch and Uncoocked and cooked grain size were significantly improved by IAA, while Grain Protein content was by Kinetin.
