Abstract: A field experiment was conducted at Farmer’s field located at Kapgari, Jhargram, West Bengal, India to study the effect of foliar nutrients on summer sesame (sesamum indicum L.) in alluvial soils of West Bengal in the year of 2021. The experiment comprised of 10 different foliar treatments viz. water spray, K2SO4 @ 0.75%, KCl @ 0.75%,KCl @ 0.5%, NaCl @0.5%, NaCl @ 0.75%, N P K 19:19:19 @ 0.5%, N P K 19:19:19 @ 0.75%, N P K 10:26:26 @1.5%, D A P @ 1.5% at 50 % flowering and seed filling stage of sesame crop. The crop was sown on Jul 2021. A recommended dose of fertilizers was applied @ N2: P2O5: K2O -60:30:30 kg/ha in the form of N- P- K 10:26:26. Half nitrogen, full of phosphate and potassium as basal dose, remaining half of N was applied at 25 DAS. The variety of the sesame crop was Tillotoma (B-67). The experiment was conducted in randomized block design with three replications. Foliar nutrients were applied at flowering and seed filling stage of the crop with special reference to scanning their effect on growth and yield of the crop during summer season of 2021. The salient features of the findings were in general, application of spray salts at 50% flowering and seed filling stage recorded better growth and yield attributing characters. Among all the foliar nutrient treatments, significantly higher grain yield was obtained by N P K 19:19:19 @0.15% followed by N:P:K19:19:19 @0.5%. The lowest grain yield was obtained by spraying of water only. It is interesting to note that all the supplementary foliar nutrients enhanced seed yield of sesame significantly over control. Highest seed yield was recorded under the foliar feeding with N P K 19:19:19 (0.75%), and effective capsule per plant recorded by the application N P K(19:19;19)@0.75% followed by N P K (10:26:26) @1.5%. The seeds per capsule was improved by the foliar application N P K (19:19:19) @0.75%. The application of N P K 19:19:19 @ 0.75% was found to be most cost-effective foliar nutrient and D A P @1.5% was found to be second most cost-effective foliar nutrient.
