Abstract:
A field experiment was carried out during kharif season of 2020 at KVK, Yagantipalli, Kurnool, Andhra Pradesh to study about the effect of Sulphur and zinc levels on growth and yield of Cluster bean (Cyamopsis tetragonoloba L. Taub). The experiment was laid out in randomized block design with closing two treatment factors, i.e., Sulphur and zinc levels i.e., S₁- 20 kg/ha, S₂-30 kg/ha and S₃-40 kg/ha and Zn₁-5 kg/ha, Zn₂-10 kg/ha and Zn₃-20 kg/ha. Results revealed that application of sulphur 40 kg/ha + zinc 20 kg/ha recorded significantly highest plant height (124.9 cm), number of branches (25.3), plant dry weight (28.92 g), number of pods/plant (42.1), seed index (3.2 g), number of seeds/pod (8.4), pod yield (4071.20 kg/ha), seed yield (1968 kg/ha) and stover yield (5123.33 kg/ha). However, net returns (39231 INR/ha) and B:C ratio (1.83) were also obtained with the application of Sulphur 40 kg/ha + zinc 20 kg/ha.
