Quality and Yield of Basmati Rice as Affected by Growth Regulators

Field experiment with eleven treatments and three replications was conducted in Randomised Block Design (RBD) at Student Instructional Farm, C. S. Azad University of Agriculture and Technology, Kanpur, (U.P), India during 2014 and 2015 to explore new approach for yield and quality enhancement. Basmati rice plants were sprayed with growth regulators at tillering and before anthesis stages which not only enhanced the yield but also increased the quality components such as starch and protein content. The treatments were; IAA 25 and 50 ppm, Kinetin, 5 and 10 ppm, CCC 2000 and 4000 ppm, SADH 1000 and 3000 ppm and ascorbic acid 50 and 100 ppm. Results showed a conspicuous increase in yield and quality components in treated plants. IAA and Kinetin possessed at pre-anthesis leaf stage significantly more leaf nitrogen, grain starch and grain protein content. Individually IAA 25 and 50 ppm caused increase in grain starch content and pre-anthesis nitrogen content of leaves while Kinetin 5 and 10 ppm enhanced grain protein content. The yield attributing traits like test weight, harvest index (HI) and grain yield were improved by the treatment of IAA 50 ppm.
