Effect of nitrogen and micronutrient levels on Frenchbean cv HUR 137 was studied in a field experiment during winter seasons of 1999-2000 and 2000-01 at Agricultural Research Farm, Banaras Hindu University, Varanasi. Plant height, dry weight, nodule number and dry weight, pod length, pod number and weight, seeds per pod, 100 - seed weight, grain and straw yields, nutrient uptake and protein harvest increased significantly up to the highest level of 180 kg N ha application recording a grain yield of 2651 kg ha-1. Application of 6 kg Zn ha1 followed by 1 kg Mo ha' recorded maximum values for the above stated attributes culminating to the maximum grain yield of 2515 kg ha. Nitrogen level of 180 kg ha1 gave the highest net return (Rs. 43,744 ha) and a benefit: cost ratio of 2.37. As regards micronutrients, application of 6 kg Zn ha1 over and above normal N, P, K, S showed the maximum net return of Rs. 42, 309 ha' with a benefit: cost ratio of 2.54.
