SUMMARY

A field experiment was conducted at Dryland Research Area, CCS Haryana Agricultural University, Hisar (Haryana), India during summer 2016. Cluster bean varieties RGC 1055, HG 2-20, RGC 1066 and NBPGR 120 were grown in three crop geometries (22.5 cm x 10 cm, 30.0 cm x 10 cm and 45.0 cm x 10 cm) with factorial randomized block design (RBD) in three replicates to find out the suitable variety and crop geometry for summer season. The inter-row spacing’s were 22.5, 30.0 and 45.0 cm but the intra-row spacing was kept 10 cm. Among different varieties, highest seed and straw yield (573.2 and 1920.1 q/ha, respectively) were recorded in the single stem variety RGC 1066 which were on a par with branched variety HG 2-20. Maximum harvest index (0.23) was noticed in HG 2-20 and the same value was also with RGC 1066. Maximum B : C ratio (1.27) was fetched in the single stemmed variety RGC 1066 followed by branched variety HG 2-20. Significantly highest gum content (32.38%) was estimated in HG 2-20. Among different crop geometries, highest seed and biological yield (473.9, 2318.9 kg/ha, respectively) were recorded at 45.0 cm x 10 cm which was on a par with 30.0 cm x 10 cm but significantly superior over 22.5 cm x 10 cm. Highest gum content (32.38%) was estimated with 45.0 cm x 10 cm, which was on a par with 30.0 cm x 10 cm. Maximum B : C ratio (1.09) was fetched with the crop geometry 45.0×10 cm. Significant interaction was observed between variety and crop geometry for seed, straw, biological yield, crude protein and gum content.
