Abstract: Present investigation entitled “Response of foliar application of plant growth regulators on growth, yield attributes and yield of coriander (Coriandrum sativum L.) in Chhattisgarh plain” was conducted during rabi season 2023-24 at Horticulture Research Cum Instructional Farm, Barrister Thakur Chhedilal College of Agriculture and Research Station, Bilaspur (C.G.). The experiment were laid out in a RBD replicated thrice with three different plant growth regulators with different levels including GA3 @ 50, 75 and 100 ppm, NAA @ 50, 75 and 100 ppm and Cycocel @ 100, 150 and 200 ppm as foliar application at pre flowering stage (30 DAS) and pre seed setting stage (50 DAS) and control plot. The results showed that the application of GA3 @ 50 ppm (T2) gave maximum plant height (cm), maximum number of branches plant-1. Among the yield and yield attributing characters such as plant height (cm), number of umbels plant-1, number of umbellate umbel-1, number of seeds umbel-1, test weight of seed and seed yield (q ha-1) were maximum with GA3 @ 50 ppm (T2). Economics study of coriander seed production showed that maximum gross return (118575.23 ` ha-1), net return (92200.23 ` ha-1) and benefit: cost ratio (3.50) were found with GA3 @ 50 ppm (T2), followed by GA3 @ 50 ppm (T3).
