The experiment was laid out in factorial randomized complete block design with three replications. The treatment consisted of six foliar dozes viz. T1 (Tap water as control), T2 (0.10 % urea), T3 (0.25 % urea), T4 (0.40 % urea), T5 (5 ppm planofix) and T6 (10 ppm planofix) and three application frequencies viz. F1 [20 days after sowing (20 DAS)], F2 (30 DAS) and F3 (20 and 30 DAS). Maximum foliage yield (6.94 t/ha) was recorded in 10 ppm planofix coupled with it’s twice application at 20 and 30 DAS which was closely followed the foliage yield (6.33 t/ha) by 5 ppm planofix with the same application frequency. The foliage yield was increased with the increase in urea concentration. The highest foliage yield (5.37 t/ha) was also recorded from twice application of urea and planofix at 20 and 30 DAS, respectively. Planofix 10 ppm with its twice application at 20 and 30 DAS gave the highest benefit-cost of ration 2.51.Int. J. Agril. Res. Innov. & Tech. 5 (1): 40-44, June, 2015
