A field experiment was conducted at Anand (Gujarat) during rabi season of the year 2013 on sandy loam soil (pH 7.2, OC 0.53 %, available nitrogen 242.32 kg ha-1, available phosphorus 21.40 kg ha-1 and available potash 172.00 kg ha-1) to evaluate the role of irrigation and nitrogen levels on yield, economic, nutrient uptake and content of French bean (Phaseolus vulgaris L.) crop. It consisted of twelve treatment combinations comparing of four irrigation scheduling (0.6, 0.8, 1.0 IW: CPE ratio and irrigation at branching, flowering, pod development and seed formation stages) three levels of nitrogen (80, 120 and 160 kg N ha-1). The experiment was laid out in split plot design and it was replicated four times to evaluate the effect of irrigation scheduling and nitrogen levels on productivity and quality of French bean. The results revealed that application of irrigation at 1.0 IW: CPE has significant effect on seed (1205 kg ha-1) straw (1523 kg ha-1) yields, harvest index (43.81 %) and quality parameters like protein content (22.57%), N content (3.61%) and nitrogen uptake by seed (43.65) as well as available soil nitrogen (261.21 kg ha-1) and economic retune, while maximum water use efficiency was noted in treatment where irrigation applied at 0.6 IW: CPE ratio. Among the different nitrogen levels, application of N applied at 120 kg ha-1 noted higher seed (1130 kg ha-1) and straw (1465 kg ha-1) yields, protein content (22.05 %), N content (3.53 kg ha-1) and N uptake from seed (40.17 kg ha-1), higher economic return, while application of nitrogen @ 160 kg ha-1 gave positive response to harvest index (43.90) and water use efficiency (4.92 kg ha mm-1).
