Abstract:
Coriander is very popular in India due to its spiciness in the seeds and aroma in the leaves. D-linalool (C₁₀H₁₇OH), also known as Coriandrol is responsible for the aroma of coriander. India is renowned for being the "Home of Spices" or "Land of Spices". Coriander ranks first among the seed spices with respect to area, production and export. The field trial was carried out at a farm of KVK, Raipur, IGKV, Chhattisgarh in 2020–21 in nine treatments of three plant growth regulators and a control with three replications in a RBD i.e., GA₃ @ 15 ppm, 30 ppm and 45 ppm, NAA @ 20 ppm, 40 ppm and 60 ppm and 2,4-D @ 5 ppm, 10 ppm and 15 ppm used as foliar application at pre flowering stage and pre seed setting stage. According to the results, application of GA₃ at 45 ppm given the highest plant height (90.36), number of primary branches plant^-1 (8.53), number of secondary branches plant^-1 (14.33), number of nodes plant^-1 (9.36), number of umbels (29.30) plant^-1, number of seeds umbel^-1 (42.64), test weight of seed (12.90 g), seed yield plant^-1 (8.43 g), seed yield ha^-1 (13.01 q), net returns (Rs. 194180 ha^-1) and B: C ratio (1:2.94). However fresh weight (32.23 g) and dry weight (16.53 g) of plant was highest with NAA @ 60 ppm. Days to 50% flowering (50) and days to seed maturity (87) were obtained minimum with 15 ppm 2,4-D.
