Effect of Application of Iron and Zinc on Growth and Yield of Cluster Bean (Cyamopsis tetragonoloba L.)

A field experiment was conducted during Zaid 2023 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The soil of the experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.36 %), available N (171.48 kg/ha), available P (15.2 kg/ha) and available K (232.5 kg/ha). The experiment was laid out in Randomized Block Design with nine treatments each replicated thrice based on one year of experimentation. The application of Iron at 15000 ppm + Zinc 20 kg/ha, recorded significantly higher Plant height (102.80 cm), number of nodules per plant (47.57) Plant dry weight (55.04 g/plant). Significantly maximum pods/plant (44.50), Seeds/pod (14.31) were recorded with the treatment of Iron at 15000 ppm + Zinc 20 kg/ha.
