Abstract:
A field experiment was conducted during Zaid 2021 at Crop Research Farm, Department of Agronomy, SHUATS, Allahabad, (U.P). The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), the available N, P, K fertilizers is applied through inorganic fertilizers i.e., Urea, Single Super Phosphate and Murate of Potash. The treatment consisted of foliar spray of boron 0.2 and 0.5% at 20 and 35 DAS and salicylic acid 50, 100, and 150ppm at 25 and 45 DAS whose effect is observed on greengram (var. Virat). The experiment was laid out in Randomized Block Design, with 10 treatments, replicated thrice. The treatment with 150 ppm salicylic acid at 25 and 45 DAS recorded significantly higher growth parameters viz., plant height (57.18 cm), number of branches per plant (8.00), number of nodules per plant (15.07), dry weight (7.16 g/plant), number of pods per plant (38.04), seed yield (1346.67 kg/ha), stover yield (2143.33 kg/ha) and harvest index (38.98%). The maximum Crop Growth Rate and Relative Growth Rate recorded with (no spray) control (4.92) and maximum RGR recorded in 0.5% Boron foliar spray at 20 and 35 DAS respectively. The maximum gross returns (97766.90 INR/ha), net returns (70954.75 INR/ha) and B:C ratio (2.64) was recorded in treatment with application of 150ppm salicylic acid at 25 and 45 DAS. Hence foliar spray of 150 ppm salicylic acid at 25 and 45 DAS found most productive and cost effective.
