Abstract
Field studies on“Study the effect of weather parameter on bacterial blight in Cluster bean [Cyamopsis tetragonoloba (L.) Taub.]”was conducted at dry land research area of department of Plant Pathology,CCS Haryana Agricultural University, Hisar during Kharif 2020. The main plot treatments consisted of three date of sowing viz., 1st week of July (D1), 2nd week of July (D2) and 4th week of July (D3) and the sub-plot treatments consisted of three varieties viz., HG 365, HG 563, HG 2-20.Nine treatment combinations were tested in randomized block design in three replications. The 1st week of July sown crop had highest agrometeorological indices, followed by 2nd week of July and 4th week of July. All growth parameters, yield and yield attributes were found highest in 1st week of July sown crop. Among different varieties, HG 563 consumed highest heat units, heliothermal units and photothermal units followed by HG 2-20 and HG 365 under different growing environments. Heat use efficiency were highest in variety HG 365.Progression of bacterial blight was found highest in variety HG 365 followed by HG 2-20 and HG 563 in all three date of sowings.Among different sowing dates crop sown on 1st week of July were recorded lowest progression of bacterial blight followed by 2nd week of July and 4th week of July.The correlation analysis were carried out to study the relationship between bacterial blight and microclimate of cluster bean varieties. Temperature minimum, relative humidity evening highly significant negatively correlated in all date of sowings and in all varieties. Relative humidity morning positively correlated in all date of sowings and in all varieties. Maximum AUDPC were recorded in 4th week of July sown crop in all varieties. Minimum AUDPC were recorded in 1st week of July sown crop in all varieties.
