Abstract

Effect of seed soaking of three plant growth regulators viz; GA3 (100, 200 and 300 ppm), kinetin (100, 150 and 200ppm) and putrescine (30, 60 and 90 ppm) were studied on a direct seeded rice (c.v. sarjoo-52), under normal and sodic soil. Total soluble carbohydrate and starch content in culm at different stages were significantly decreased in sodic condition over normal. Among growth regulators, putrescine 30ppm proved most effective and improved both starch and carbohydrate contents in sodic condition. Reverse trend was noted in catalase and peroxidase activity under sodicity. However, kinetin 100 ppm favored catalase activity and putrescine 30 ppm favored peroxidase activity at 120 DAS stage showed lower values compared to other growth regulators tried. Na content in plants increased significantly with a concomitant decrease in K and Ca content in sodic soil. Of the three regulators, kinetin 150 ppm and putrescine 60 ppm retained higher Na K, and Ca under sodic condition. Grain yield and its attributes also declined significantly in sodic soil. Seed soaking with putrescine 30 ppm appeared most effective, followed by GA3 300 ppm which increased yield and panicle length under sodic condition.
