A field experiment was conducted at Vegetable Research Farm, College of Horticulture, Mandsaur (MP) during rabi season of 2014-15 to investigate the influence of irrigation regimes and varieties on growth, yield and quality of onion. The treatments comprised of three levels of irrigation (1.0, 0.75 and 0.50 IW: CPE ratio) and three different varieties (NHRDF Red-1, NHRDF Red-3, Agrifound Light Red). The experiment was laid out in split plot design with three replications. The irrigation level I1 (IW:CPE=1.0) was found better for all growth attributes like plant height, number of leaves, fresh weight of plant, dry weight of plant, leaf area. The yield characters viz. dry weight of bulb, equatorial diameter, polar diameter, average weight of bulb and total yield of bulb were maximum in I1 (IW:CPE=1.0). Maximum neck thickness and T.S.S. of bulb was measured in case of irrigation level I1 (IW: CPE=1.00). Highest water use efficiency was found with irrigation level I1 which decreased with increase in irrigation interval (decreasing IW/CPE ratio). Variety V3 (Agrifound Light Red) recorded maximum plant height, number of leaves, fresh weight of plant, dry weight of plant, leaf area. Yield and yield parameters viz. maximum dry weight of bulb, equatorial diameter, polar diameter of bulb, average weight of bulb and total bulb yield per hectare were observed with V2 (NHRDF Red-3). Maximum neck thickness and highest T.S.S. content of bulb was recorded in case of V3 (Agrifound Light Red). Maximum Gross income, net income and B: C ratio was recorded under Irrigation level I1 (IW: CPE=1.0) and variety V2 (NHRDF Red-3).
