Abstract

Field experimentation was conducted during kharif 2020 at KVK, Kalyandurg, Anantapur, and Andhra Pradesh. The soil of experimental plot was sandy loam in texture, Basic in soil reaction (pH 8.29), low in organic carbon (0.20%), available N (190.6 kg/ha), available P (37 kg/ha), available K (100 kg/ha) and available sulphur (9.5 kg/ha). The treatments which are Phosphorus at 40, 50, 60 kg/ha along with it sulphur at 15, 20, 25 kg/ha and control treatment with farmer practice at 20+40+20 kg/ha (N+P+K kg/ha) was used. The research was laid out in Randomized Block Design with ten treatments each replicated three times. In that study maximum plant height (86.00 cm), Branches/plant (21.80) plant dry weight (15.99 g/plant), Crop growth rate (2.37 g/m2/day), Relative growth rate (0.03 g/g/day), Maximum Pod/plants (10.57), Maximum Pod length(16.26 cm), Pod yield (11.69 t/ha), Grain yield (3.41 t/ha), Stover yield (7.4 t/ha) seed index (4.47 g/100 seeds) and Maximum Harvest index (32.99 %) noted

Keywords

Cluster bean, Phosphorus, sulphur, Growth, Yield.

Conclusion

On the basis of study, Anantapur, Andhra Pradesh region conditions are much better suitable for growing cluster bean due to its hot and humid conditions, in that this present investigation suggested that by Phosphorus (P) 60 kg/ha + Sulphur (S) 20 kg/ha resulted highest plant height (86.00 cm), branches per plant (21.80 no.), pods/plant (10.57), pod length (16.26 cm) as well as yield of (3.41 t/ha) and stover yield (7.35 t/ha) were recorded in cluster bean
