| Popis: | An experiment was conducted to study the effect of pre harvest foliar application of growth regulators on the pre and post harvest flower quality in ornamental sunflower during the year 2012-13, at College of Horticulture, GKVK campus, UHS, Bagalkot. At 60 DAS highest plant height was with GA3 @ 150 ppm (154.73 cm) followed by GA3 @ 200 ppm (146.20 cm) and GA3 @ 250 ppm (145.53 cm). Sodium silicate @ 250 ppm (4508.77 cm2) registered maximum plant spread at 60 DAS. Foliar application of GA3 @ 150 ppm (25.00) produced highest number of leaves which was at par with Sodium silicate @ 250 ppm, GA3 @ 200 ppm and GA3 @ 250 ppm recording 24.87, 24.80 and 24.67 leaves respectively. Calcium sulphate @ 200 ppm registered highest leaf area of (4930.30 cm2) which was at par with Sodium silicate @ 250 ppm, Calcium sulphate @ 300 ppm, Chlormequat chloride @ 500 ppm, Sodium silicate @ 350 ppm, and Chlormequat chloride @ 1000 ppm with 4792.64, 4735.04, 4721.75, 4503.05 and 4430.02 cm2 respectively. |
