Abstract

The field experiment was carried out during Rabi seasons for the years 2007-08 and 2008-09 in sandy loam soil at Horticultural Research Farm, Department of Horticulture, B. A. College of Agriculture, Anand Agricultural University, Anand in Randomized Block Design with three replications. The growth regulators GA 3 and NAA each @ 50, 100 and 150 mg/l were tried as root dipping, foliar spray as well as their combinations and compared with control. The application of GA 3 50 mg/l as root dipping + foliar spray significantly increased volume of bulb, equatorial and polar diameter of bulb as well as bulb yield, while average weight of bulb was significantly increased in GA 3 100 mg/l as root dipping + foliar spray. The other characters viz. , number of leaves per plant, TSS and dry matter content of bulb were found non-significant. The physiological loss of weight, spoilage loss and finally total loss were significantly reduced under NAA 100 mg/ l as root dipping treatment when compared to control.
