Abstract
A field experiment was conducted during the Zaid (summer) season of 2023 to study the “Response of Phosphorus and Gibberellic acid on growth and yield of Black gram (Vigna mungo L.)” at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (Uttar Pradesh). The soil of the experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), medium in organic carbon (0.53 %), low in available N (171.48 kg/ha), medium in available P (33.6 kg/ha) and high in available K (244.5 kg/ha). The experiment was laid out in Randomized Block Design with Ten treatments each replicated thrice based on one year of experimentation. The treatments consisted of 3 levels of Phosphorous [30 kg/ha, 40 kg/ha and 50 kg/ha] and three levels of Gibberellic acid [100 ppm, 125 ppm and 150 ppm] and Control (RDF) 20- 40- 20 kg NPK/ha are used. The results showed that the application of Phosphorus at 50 kg/ha and Gibberellic acid at 150 ppm, recorded significant growth parameters viz., Plant height (35.84 cm), nodules per plant (25.57/plant), Plant dry weight (10.41 g/plant), yield attributes like pods/plant (24.53/plant), Seeds/pod (8.00/pod), test weight (33.56 g), Seed yield (1441.23 kg/ha), stover yield (3191.10 kg/ha) and harvest index (31.10%). The highest net economic returns (Rs.46,984.20 /ha) and benefit-cost ratio (1:1.5) were also recorded in the same treatment concludes that application of 50 kg/ha of phosphorous along with foliar spray of 150 ppm gibberellic acid at 15 and 30 days after sowing performed better and is economically profitable.
