A field trial was steered to ascertain the outcome of foliar application of NPK and micronutrients on nutrient content and uptake by sesame crop during the summer season of 2022 on medium black calcareous soil of Instructional Farm, Junagadh Agricultural University, Junagadh, India. The experiment was conducted with three replications and 10 treatments by using Randomized Block Design (RBD), the GJT-5 variety of sesame was tested in this experiment. The treatment consists of 100 % recommended dose of fertilizer (RDF), viz. 50:25:40 N-P2O5-K2O kg /ha (T1), T1 + Foliar spray of multi micro. mixture grade-IV (MMMG) @ 0.25 % at 30 and 45 days after sowing (DAS) (T2), 75 % of RDF + 1.5 % Water Soluble Fertilizer at 30 and 45 DAS (T3), 75 % of RDF + 2.0 % Water Soluble Fertilizer at 30 and 45 DAS (T4), 50 % of RDF + 1.5 % Water Soluble Fertilizer at 30 and 45 DAS (T5), 50 % of RDF + 2.0 % Water Soluble Fertilizer at 30 and 45 DAS (T6), T3 + Foliar spray of multi micro mixture grade - IV @ 0.25 % at 30 and 45 DAS (T7), T4 + Foliar spray of MMMG- IV @ 0.25 % at 30 and 45 DAS (T8), T5 + Foliar spray of MMMG- IV @ 0.25 % at 30 and 45 DAS (T9) and T6 + Foliar spray of MMMG- IV @ 0.25 % at 30 and 45 DAS (T10). The results of the experimentation revealed that the application of T4 + Foliar spray of MMMG- IV @ 0.25 % (T8) at 30 and 45 DAS) recorded the significantly higher content of N, P and K and micronutrients (Fe, Zn, Mn, Cu and B) in seed and stover of sesame and also enhanced the uptake of these nutrients by plant as well as the availability of Nitrogen, Phosphorous and Potassium in soil after harvest of the crop. Significantly, they were at par with the application of T3 + Foliar spray of MMMG- IV @ 0.25 % (T7) at 30 and 45 DAS). While, the significantly lowest values of nutrient content and uptake were recorded with 50 % of RDF + 1.5 % Water Soluble Fertilizer (T5) at 30 and 45 DAS.
