“…The decrease in total chlorophyll content was observed by application of GA3 @100 ppm might be due to lanky growth of plant leading to wiry appearance in the architecture which further had led to masking effect from light and thus inhibiting the synthesis of chlorophyll molecule to the maximum possible extent by the plants. The results in corroborate with the findings of Shanu et al [13], Kuri et al [18] in coriander and Choudhary et al [22] in ajowan.…”

A field experiment was carried out during rabi season of 2018-2019, at college farm, College of Horticulture, Dr. Y.S.R. Horticultural University, Venkataramannagudem, West Godavari District, Andhra Pradesh. The experiment was laidout in a Randomised Block Design with eleven treatments (viz., T1- NAA @ 50 ppm, T2-NAA @ 100 ppm, T3-GA3 @ 50 ppm, T4-GA3 @ 100 ppm, T5-Thiourea @ 250 ppm, T6-Thiourea @ 500 ppm, T7-28-Homobrassinolide @ 0.1 ppm, T8-28-Homobrassinolide @ 0.2 ppm, T9-Triacontinol @ 2.5 ppm, T10-Triacontinol @ 5 ppm, T11-(Control) Water spray) and three replications. The treatments were imposed at 30 and 45 DAT in the form of foliar spray. Foliar application of GA3@ 100 ppm (T4) had recorded the maximum plant height (108.20 cm), leaf area (9.53 cm2) and leaf area index (0.74). Foliar application of thiourea @ 250 ppm (T5) had recorded the maximum values with respect to number of primary branches (15.03 plant-1), number of secondary branches (83.40 plant-1), plant spread (1793 cm2 plant-1), fresh weight (376.29 g plant-1), dry weight (103.54 g plant-1) and number of leaves plant-1((298.8). The same treatment (T5) had recorded the highest values with respect to crop growth rate (1.44 gm-2d-1), chlorophyll-a (1.40 mg g-1), chlorophyll-b (0.076 mg g-1) and total chlorophyll contents (1.48 mg g-1) in the leaves.

“…The sulphydryl group present in thiourea might have improved the activity of starch synthase enzyme and helps in effective filling of seeds as earlier reported by Gupta and Yadav [13] in fenugreek. The results are in consent with the findings of Sumeria [16] in mustard, Bochalia et al [11] in fenugreek, Singh et al [9] in coriander and Choudary et al [15] in ajowan.…”

“…The increase in seed yield hectare -1 with the application of thiourea by 250 ppm as foliar spray might be due to corresponding increase in seed yield plant -1 and seed yield plot -1 . The results are incorroborate with the findings of Gupta and Yadav [13] in fenugreek, Shanuet al [14]; Singh et al [9] in coriander and Chowdary et al [15] in ajowan.…”

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).

“…GA 3 application at 100 ppm is effective to give maximum growth and seed yield (7.47 g) as it is involved in cell elongation leading to increase in cell wall plasticity (Mohit et al, 2016) [31] . The higher number of umbels per plant (184.0), number of seeds per umbel (212.30) and seed (1112 kg/ha), straw (3082 kg/ha) and biological yields (4195 kg/ha) were obtained with application of thiourea @ 500 ppm spray at 40 and 60 DAS (Sheeshpal et al, 2017) [48] . Application of 100 mg/L NAA emerged as the best treatment to enhance the yield attributes followed by GA 3 .…”
