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.
