Interactions (S×V) * * * * *
Among the interactions, the genotypes RC 1033, RC 938 and RGC 1038 performed well
under 45×10cm and 30×10cm geometry and produced significantly higher seed yield
compared to other combinations. Similar trend was observed with respect to economics
and RWUE. The genotype RC 1033 and RGC-938 showed superiority over the rest due to
production of more pods per plant by utilisation of rain water more efficiently, which leads to
effective translocation and distribution of photosynthates from source to sink in turn more pod
yield per plant. Similar kind of observations made by Satpal et al. (2020) and Gangadhara
(2013) in case of cluster bean.

Conclusion
The study concluded that the crop geometry of 30 × 10 cm and 45 × 10 cm is ideal for cluster
bean genotypes RC 1033 and RGC-938 for getting higher yield and economic returns in
northern dry zone of Karnataka.
