Alfalfa is an important medicinal plant having stachydrine as alkaloid and used as laxative, digestive, diuretic and treating for dropsy, blood pressure, hair loss, acidity and arthritis. Present investigation was carried out during rabi season 2019-20, Dept. of PMA, College of Horticulture, Bagalkote with the objective to study the effect of plant growth hormones on yield characteristics of Alfalfa (Medicago sativa L.) under Northern dry Zone of Karnataka. In this experiment, the growth hormones viz., GA3 (50 ppm and 100 ppm), IAA (50 ppm and 100 ppm), NAA (50 ppm and100 ppm), Kinetin (50 ppm and 100 ppm), Humic acid (4.0ml/l and 6.0ml/l), Salicylic acid (1.5 g/l and 3 g/l) and water as control were sprayed at 30, 60, 90 and 120 days after sowing and analysed for yield parameters. Among different growth hormones, the plants sprayed with GA3 at 100 ppm showed significantly highest fresh leaves weight (41.17, 46.77, 36.20 and 27.67 g/plant), fresh stem weight (33.03, 33.51, 24.27 and 22.40 g/plant),  fresh herbage yield per hectare (16.59, 17.73, 13.43 and 11.12t/ha), highest dry leaves weight (8.52, 9.71, 7.97 and 7.32 g/plant), stem dry weight (8.98, 9.57, 8.71, 8.09 g/plant) and dry herbage yield (4.01, 4.15, 3.70 and 3.42t/ha) at I, II, III and IV harvest i.e. on 50, 80, 110 and 140 DAS, respectively. It is concluded that foliar application of plant growth regulators at different intervals significantly increased the alfalfa yield as compared to control. This study specified that, among different growth regulators, the plants sprayed withGA3 at 100 ppm showed better results for yield attributes of alfalfa.
