An experiment was carried out with Gibberellic Acid (GA3) to evaluate its effects on the sprouting and early growth behavior of a local and an exotic cultivar of garlic. The aim of the experiment was to investigate possible ways to overcome the problem of dormancy in garlic. The local cultivar exhibited marked influence of GA3 on sprouting of cloves, number of leaves /plantlet, plantlet heigh4 number of roots /plantle4 root length and percentage of normal plantlets. The 250 ppm concentration of GA3 gave the maximum sprouting (31.67%) whereas the 500 ppm concentration produced the minimum sprouting (10.00%). The exotic cultivar completely failed to sprout. The results revealed that application of GA3 has the potentiality to break dormancy and accelerates the sprouting in the local cultivar of garlic.
