Description A field experiment was conducted during “rabi” (January-February) of 2012 in sandy loam soils of Model orchard, College of Horticulture, Dr. Y.S.R. Horticultural University, Rajendranagar, Hyderabad, Andhra Pradesh to study the “Effect of plant growth regulators on growth, herbage yield and quality of coriander” cv. Swathi (CS-6). The experiment was laid out in split plot design consisting of modes of application of plant growth rgulators viz., pre plant soaking (8hrs), spraying at 20 DAS and pre plant soaking (8 hrs.) + spraying at 20 DAS as main plot treatments and various plant growth regulators i.e., GA3 (30 and 45 ppm), NAA (20 and 30 ppm), TRIA (1 and 2 ppm) and BA (5 and 10 ppm) as sub plot treatments. The results emanated from the experiment revealed that the different plant growth regulators applied by various modes were found to have a significant effect on all the growth, yield and quality parameters. Among the modes of application of plant growth regulators, pre plant soaking (8 hrs.) + spraying at 20 DAS recorded the maximum growth and yield parameters like plant height, number of leaves and nodes plant-1, fresh weight of leaves and shoot plant-1, leaf to shoot ratio, total dry matter plant-1 and herbage yield ha-1 as well as the biochemical parameters like leaf chlorophyll, ascorbic acid and leaf essential oil content followed by spraying at 20 DAS and the respective minimum values were recorded in pre plant soaking (8hrs). Among the different plant growth regulators applied at various concentrations, GA3 @ 45 ppm recorded the highest values followed by NAA @ 20 ppm regarding all the above growth, yield and biochemical parameters. Similarly, the interaction between various concentrations of different plant growth regulators and their mode of application, pre plant soaking (8 hrs.) + spraying at 20 DAS with 45 ppm GA3 was the best compared to any other combination followed by pre plant soaking (8 hrs.) + spraying at 20 DAS with NAA @ 20 ppm regarding all the growth, yield and quality parameters. However, the maximum net returns was obtained in pre plant soaking (8 hrs.) + spraying at 20 DAS with NAA @ 20 ppm followed by pre plant soaking (8 hrs.) + spraying at 20 DAS with GA3 @ 45 ppm and the highest benefit cost ratio was obtained in pre plant soaking (8 hrs.) + spraying at 20 DAS with NAA @ 20 ppm followed by spraying at 20 DAS with NAA @ 20 ppm. The results of the present investigation demonstrated that pre plant soaking (8 hrs.) + spraying at 20 DAS with GA3 45 ppm solution can be considered as the best treatment for obtaining higher herbage yield of better quality in coriander.
