Abstract
A field experiment was conducted at Pusa (Bihar) during the winter season ( rabi) of 1991-92 and 1992-93, to study the response of irrigation and nitro gen fertilization on French bean (Phaseolus vulgaris L.). Significant incre ase in seed yield was recorded with 3 irrigations in both the years. During the first year, it was maximum when irrigation was applied on days interva l basis, while during second year an at IW : CPE ratio of 0.8. The differen ce between 2 and 3 irrigations applied through both the approaches was not significant in the second year. Growth and yield attributes were maximum un der 2-3 irrigations, whereas water-use efficiency was maximum with 1 irriga tion. Inconsistent results were observed for plant height, branches and lea ves/plant with 80 and 120 kg N/ha during both the years. There was a linear increase. in Seed yield and pods/plant due to increase in N level from 40 to 120 kg/ha. Seeds/pod and test weight increased significantly up to 80 kg N/ha.
