Abstract:
A field experiment was conducted at Professor Jayashankar Telangana State Agricultural University, Hyderabad in rainy season of 2013-14 to study the “Performance of clusterbean varieties at varied crop geometry” The experiment was laid out in factorial randomized block design with three replications to evaluate the performance of promising varieties of clusterbean (V₁- RGC 1025, V₂- HGS 365, V₃- RGC 936 and V₄- RGC 1017) and to standardize the crop geometry levels (S₁- 30 x 7.5 cm, S₂- 30 x 10 cm, S₃- 37.5 x 10 cm and S₄- 45 x 10 cm) under rainfed semi-arid conditions of Andhra Pradesh. The results indicated that among the four varieties tested plant height, dry matter accumulation, leaf area, number of branches/plant^, crop growth rate (CGR) and pods plant^-1 of RGC 1025 variety was significantly higher as compared to other varieties followed by RGC 936, HGS 365 respectively, RGC 1017 showed inferior performance with respect to growth. Variety RGC 936 recorded earlier 50 per cent flowering and maturity followed by RGC 1025 and Similarly, Seed, stalk, gum and protein yield were significantly higher with variety RGC 1025 which was distinctly superior over other varieties and followed by RGC 936, HGS 365 and RGC 1017 respectively, However, RGC 936 found to be higher gum producing variety while protein content was higher with HGS 365. NPK uptake was significantly higher with variety RGC 1025 compared to rest. Clusterbean performed well under closer crop geometry i e. 30 x 7.5 cm and almost similar results were obtained under 30 x 10 cm compared to wider crop geometry 45 x10 cm regarding growth and yield, Therefore it can be concluded that RGC 1025 and RGC 936 planting at closer geometry (30 x 10 cm) are best suited and can be recommended to rainfed semi-arid area of Andhra Pradesh.
