Abstract
Foliar application of plant growth regulators viz., GA3 -50& 100 ppm, NAA- 50 ppm &100 ppm, Thiourea- 250 & 500 ppm, 28-Homobrassinolide- 0.1& 0.2ppm, Triacontanol - 2.5& 5 ppm and Control. All the treatments were applied as foliar sprays at 30 and 45 DAT. Days to 50% flowering (46 d) and days to harvest (100.20 d) were found earlier in ajowan with the foliar applications of triacontanol by 5 ppm (T10).The same treatment had recorded the maximum number of umbellate umbel-1(14.20). Foliar applications of thiourea by 250 ppm (T5) had record the highest values with respect to yield, yield attributing characters viz number of umbels plant-1(228.70), number of seeds umbel-1(183.60), number of seeds umbellate-1(13.50), test weight (1.56 g), seed yield plant-1 (28.50 g), seed yield plot-1 (1425 g), seed yield hectare-1(1583.33 kg), harvest index (69.71%) and quality parameters viz essential oil (3.64%) and protein contents (19.26 mg 100 g-1).
