Abstract: An experiment was conducted on Jasminum sambac cv. Mysuru Mallige to study the effect of different levels of fertigation and micronutrients spray on yield and cost economics at Doddamaragowdanahalli village, Mysuru. The design used for the experiment was RCBD with 9 treatments and 3 replications. As there is no standard fertigation schedule for Mysuru Mallige, so the farmer practicing dosage (200 DAP, 200 g MOP, 50g Urea/plant/year) was considered as a control. The yield parameters of Jasminum sambac cv. Mysuru Mallige in terms of 100 bud weight (29.92g), flower yield per plant (725.20g), flower yield per hector (3.23 t), Shelf life (34.10 hr) and cost-benefit ratio (1:2.46) increased significantly in the plant nourished with 100% RDF (60:120:120 NPK g/plant/year) through fertigation along with a foliar spray of micronutrients (Humic acid at 0.5%, Chelated Zinc and Borax at 0.75g each per plant).
