Abstract:
In the present study, a field experiment with eleven treatments and three replications of each treatments was conducted with Randomised Block Design (RBD) inStudent Instructional Farm, C. S. Azad Uni. of Agriculture and Technology, Kanpur, (U.P), India, to explored new approach for yield and quality enhancement. Basmati rice plants were sprayed with growth regulators at tillering and before anthesis stage. Which were not only appreciate the yield but also increase the quality components. 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 components in treated plant. IAA and Kinetin, possessed a significant more number of tillers, leaves, biomass, grain starch conetnt (%), grain protein content (%), pre-anthesis leaf nitrogen content. IAA caused increase in grain starch content, pre-anthesis nitrogen content of leaves while Kinetin 5 and 10 appreciated grain protein content. The yield attributing traits like number of panicle/plant, number of grains/panicle, grain weight, biomass, Harvest Index (HI) and finally grain yield was improved by the treatment of IAA 50 ppm.
