ENHANCING YIELD OF BLACKGRAM VARIETIES BY APPLYING DIFFERENT HERBICIDES

Abstract

An experiment was carried out at the central farm of Sher-e-Bangla Agricultural University, Dhaka during the period from March to June, 2017 to enhance the yield of blackgram by applying different herbicides. Three blackgram varieties viz. V 1 (BARI mash-1), V 2 (BARI mash-2) and V 3 (BARI mash-3) and four herbicides viz. T 1 = Hammer 24 EC (Carfentrazone Ethyl) at 2 ml liter -1 , T 2 = Gramaxon (Paraquate Dichloride) at 3 ml liter = Panida (Pendimethalin) at 4 ml liter -1 and T 4 = Whip super (Fenoxaprop-p-Ethyl) at 1.5 ml liter -1 were tested for the study. The experiment was laid out in a Randomized Complete Block Design with three replications. The effect of variety, herbicides and their interactions were significant on most of the parameter measured. In the study the combined effect of V 3 T 4 was found to be significant in list of the highest number of pods plant -1 (16.30), number of seeds pod -1 (6.64), pod length (4.26 cm) and grain yield (1434.40 kg ha ). Whereas, the lowest number of pods plant -1 -1 , T 3 (3.90), number of seeds pod

(5.57) and grain yield (886.60 kg ha -1 ) were recorded from the treatment combination of V 1

T 3 .
