Background: Field experiment was conducted under In-house Project of the University during kharif seasons of 2015 and 2017 for evaluation of clusterbean varieties for Koshi Region of Bihar. Methods: The experiment was conducted by using randomized complete block design with three replications. Observations were recorded on different agronomic parameters including, plant height, dry matter accumulation, days to maturity, number of pods per plant, number of grains per pod, test weight, grain yield, biological yield and harvest index. Economics of crop was also calculated to find out the economic feasibility for the farmers. Result: Result revealed that the significantly taller plants along with higher dry matter accumulation was observed under clusterbean variety Bundel Guar-2 (BG-2). Clusterbean variety Gujarat Guar-2 (GG-2) taken least number of days to maturity, however, highest number of days to maturity was taken by RGC-986 and BG-1. Significantly higher number of pods per plant was observed under RGC-1033. HG-365 resulted into significantly higher number of grains per pod and BG-1 recorded significantly higher test weight. RGC-1033 proved significantly better in terms of grain yield, harvest index and net returns. In terms of stover and biological yield BG-2 proved significantly superior.
