EFFECT OF GROWTH REGULATORS AND PHOSPHORUS LEVELS ON) GROWTH AND YIELD OF SOYBEAN

Abstract

Foliar spray of different growth regulators significantly influenced the plant growth and yield attributing characters. Highest yield response was obtained by triacontanol (13.51 q/ha) closely followed by kinetin (12.95 q/ha), as compared to control (12.02 q/ha). Significant increase in the uptake of N, P and K was observed due to application of growth regulators. Triacontanol significantly increased N. P and K uptake whereas Kinetin increased N and P uptake over control. LAI was significantly increased due to application of all the three growth regulators where the chlorophyll content was significantly increased only due to triacontanol.
