Abstract:
A Field experiment was conducted during kharif 2021 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.3), low in organic carbon (0.57%), available N (230 kg/ha), available P (32.10 kg/ha) and available K (235 kg/ha). The treatments consist of three levels of nitrogen and three levels of potassium. The experiment was laid out in randomized block design with nine treatments each replicated thrice. The result showed that viz: Plant height (140.97 cm), number of branches per plant (3.62) and dry weight (14.94 g/plant) were recorded significantly higher with application of Nitrogen 50 kg/ha + Potassium 30 kg/ha. Whereas, crop growth rate (7.71 g/m²/day) at 30-45 DAS interval and relative growth rate (0.092 g/g/day) at 30-45 DAS interval recorded significantly higher with application of Nitrogen 50 kg/ha + Potassium 30 kg/ha. Number of capsules per plant (28.51), number of seeds per capsule (46.63), seed yield (1242.74 kg/ha), stalk yield (1695.68 kg/ha) and were recorded significantly higher with the application of Nitrogen 50 kg/ha + Potassium 30 kg/ha.
