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 Keywords on yield characteristics of Alfalfa Medicago sativa L. under Northern dry Zone of Alfalfa Plant Karnataka. In this experiment the growth hormones viz. GA3 50 ppm and 100 ppm IAA growth hormones 50 ppm and 100 ppm NAA 50 ppm and100 ppm Kinetin 50 ppm and 100 ppm GA3 Yield Humic acid l and l Salicylic acid g l and 3 g l and water as control attributes 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 Article Info significantly highest fresh leaves weight and g plant fresh stem weight and g plant fresh herbage yield per hectare Accepted and ha highest dry
