Abstract

Four plant growth regulators namely NAA (15, 30 and 45 ppm), 2,4-D (2, 4 and 6 ppm), PCPA (25, 50 and 75 ppm) and CCC (300, 400 and 500 ppm) were sprayed on yard long bean (cv. ‘Lola’) at different stages of growth to evaluate its impact on flowering and fruit set. Foliar spray of NAA (15 ppm) at 15, 30 and 45 days after sowing increased fruit set and productivity, giving the highest yield of 7.49 t ha-1, followed by CCC at 300 ppm. 2,4-D and PCPA had a strong depressing effect on growth and productivity.
