Abstract

At CCS Haryana Agricultural University, Hisar, Haryana, a field study was conducted to investigate the impact of varying planting timings, varieties, and weather parameters on the advancement of bacterial blight in clusterbean. The experiment was set up in three replications using a factorial randomized block design. Three types of cluster beans, namely HG 365, HG 563, and HG 2-20, were sowed at three distinct dates i.e., the 1st, 3rd, and 4th week of July. Clusterbean bacterial blight spread faster in late-planted crops (4th week of July) than in timely-planted (2nd week of July) and early-planted (1st week of July). Maximum temperature (Tmax) and maximum relative humidity (RHm) correlated positively, while minimum temperature (Tmin) and minimum relative humidity (RHe) correlated negatively, and disease development was extremely significant and negatively correlated for HG 365 at all sowing dates. Clusterbean HG 365 was shown to be more resistant to bacterial blight than HG 563 and HG 2-20.
