Abstract: A field experiment was conducted during rabi season of 2016-17 on clayey soil at Instructional Farm, Department of Agronomy, College of Agriculture, Junagadh Agricultural University, Junagadh to study the effect of recommended dose of fertilizer 120:60:60 NPK kg ha-1along with foliar spray of water soluble fertilizers viz., 19:19:19, 13:40:13, 12:61:00, 00:52:34, 28:28:00, 00:00:50:17.5 S, Urea and KNO3 on growth and yield of sweet corn var. Madhula in randomized block design with three replications. Foliar spray of water soluble fertilizers, urea and KNO3 will be done @ 2 % (20 g liter-1 water) with soil application of RDF (120:60:60 NPK kg ha-1) at 30, 45 and 60 DAS, the entire dose of phosphorus, potassium and 1/3rd dose of nitrogen was applied as basal. Remaining dose of nitrogen was applied in two splits 30 & 60 DAS. The results of experiment indicated that growth parameters viz., plant height and dry matter accumulation at 30, 45, 60 DAS and at harvest increased significantly with the application of RDF 120:60:60 kg ha-1 NPK along with foliar spray of WSF (19:19:19) @ 2 per cent at 30, 45 and 60 days after sowing and also gave significantly higher green cob and green fodder yields of 7040 kg ha-1 and 38737 kg ha-1, respectively. The highest net return (₹ 65714 ha-1) and B: C ratio (2.51) was accrued under the same treatment. In contrast, the control (T1) recorded minimum net profit as well as BCR.
