Abstract

A field experiment was conducted during rabi 2007–08 and 2008–09 at Agronomy Farm, College of Agriculture, Parbhani, Maharashtra to evaluate the effect of irrigation levels and nutrient management on root yield and water use of sugarbeet. Sugarbeet irrigated at four levels of IW: CPE ratio i. e. 0.6, 0.8, 1.0 and 1.2 and four doses of nutrient management i. e. 100: 50: 50 NPK kg/ha, 150: 75: 75 NPK kg/ha, NPK on soil test basis and 100: 50: 50 NPK kg/ha+10 t FYM/ha. The results revealed that the irrigation scheduled at 1.2 IW: CPE ratio with application of 150: 75: 75 NPK kg/ha recorded the highest root yield (70.81 t/ha), consumptive use (622 mm), water use efficiency (114 kg/ha mm), net returns (Rs. 62150/ha) and B: C ratio (3.08: 1).
