Effect of Irrigation Scheduling (IW: CPE Ratio) and Nitrogen on Yield and Economics of Rajma (Phaseolus vulgaris L.) under Middle Gujarat Conditions

A field experiment was conducted during rabi season of the year 2012–13. 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 conducted in split plot design and it was replicated four times. Higher values of growth characters, yield attributes, seed and straw yield were recorded under treatment I₃ (1.0 IW: CPE) and N₂ (120 kg N ha⁻¹). The maximum net realization of ‘ 26876 ha⁻¹ and B: C ratio 1.22 was recorded at 1.0 IW: CPE ratio. The treatment combination I₃N₂ produced significantly higher seed yield (1406 kg ha⁻¹).
