Use of growth regulators

 
• A spray of GA3 100 ppm at the five-leaf stage increases the male flowers, while Ethrel and CCC reduce the ratio of bisexual and male flowers. GA3 from 5 ppm upto 50 ppm hastens and improves flowering, when sprayed at the five-leaf stage; BA counters the effect of GA. Soaking the seeds in 50 ppm IAA improves flowering, while ascorbic acid increases the frequency of bisexual flowers. The application of Magnesium chlorate at 8 kg/ha at the waxy stage of ripening makes harvesting easier and improves the essential oil content.
