Response of Sulphur and Zinc on Growth and Yield Components of Cluster Bean

Abstract

Field test carried out during Zaid 2023 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences (SHUATS), Prayagraj (U.P). The soil in the field was found to be sandy loam, neutral in soil reaction (pH 7.10), natural carbon (0.50%), accessible N (183.40 kg/ha), accessible P (37.56 kg/ha) and accessible K (200.06 kg/ha). The experiment was a randomized block design as the experiment consisting of nine treatments each repeated three times. The treatment combinations are 1: Sulphur 10 kg/ha + Zinc 3 kg/ha, 2: Sulphur 10 kg/ha + Zinc 6 kg/ha, 3: Sulphur 10 kg/ha + Zinc 9 kg/ha, 4: Sulphur 20 kg/ha + Zinc 3 kg/ha, 5: Sulphur 20 kg/ha + Zinc 6 kg/ha, 6: Sulphur 20 kg/ha + Zinc 9 kg/ha, 7: Sulphur 30 kg/ha + Zinc 3 kg/ha, 8: Sulphur 30 kg/ha + Zinc 6 kg/ha, 9: Sulphur 30 kg/ha + Zinc 9 kg/ha, 10: Control 20:40:25 (N:P:K) kg/ha are used. The important findings of the experiment have been summarized and concluded here under the objectives taken. The application of Sulphur 30 kg/ha + Zinc 6 kg/ha, observed maximum Plant height (104.00 cm), highest number of nodules per plant (16.93) Plant dry weight (26.56 g/plant). Maximum pods/plant (41.07), Seeds/pod (10.00), Test weight (4.45g), Seed yield (2.03 t/ha), stover yield (3.98 t/ha), Harvest index (33.76%) were noted with the treatment combination of Sulphur 30 kg/ha + Zinc 6 kg/ha.
