ABSTRACT
The effect of GA3, NAA, Maleic hydrazide and Cycocel was investigated on yield, yield attributes and quality traits of Jamnagar variety of garlic at different concentrations. The results revealed higher yield per plant, yield per plot and yield per hectare, bulb fresh and cured weights, number of cloves per bulb, size of cloves, per cent large sized bulbs, and shoot : bulb ratio, along with higher TSS, total sugars, reducing and non-reducing sugars, sulphur content and ascorbic acid content with the application of GA3 at 200, 400 and 600ppm; NAA at 50, 100 and 150ppm; Maleic hydrazide at 500, 1000 and 1500ppm; and cycocel at 500, 1000 and 1500ppm, at different stages compared to control, during 2011-12 and 2012-13. Further, maximum yield per plant, yield per plot and yield per hectare, along bulb fresh and cured weights, number of cloves per bulb, size of cloves, per cent large sized bulbs, and shoot: bulb ratio, TSS, total sugars, reducing and non-reducing sugars, sulphur content and ascorbic acid content were recorded with the application of GA3 @ 200ppm. In conclusion, application of GA3 @ 200ppm had resulted in maximum yield and quality and hence, may be recommended for increasing yield in garlic.
