Abstract:

Weeds pose serious threat to soybean productivity, and chemical means are usually employed to combat weed menace in field crops. A field study was undertaken at Product Testing Unit, JNKVV, Jabalpur during Kharif season 2013 and 2014 to appraise the efficacy of propaquizafop and imazethapyr mixture against weeds and their influence on yield and economics of soybean. The experimental field was dominated by grasses (65.15%) followed by broad leaved weeds (23.51%) and sedges (11.34%). Post-emergence application of propaquizafop (75 g/ha) alone curbed only grassy weeds. However, its efficacy was improved when applied in combination with imazethapyr being higher under propaquizafop + imazethapyr mixture applied at 53 + 80 g/ha or higher rate (56 + 85 g/ha). Yield was superior under propaquizafop + imazethapyr mixture applied at 56 + 85 g/ha followed by 53 + 80 g/ha which were comparable to hand weeding twice at 20 and 40 DAS. Highest marginal benefit-cost ratio (MBCR) was found under propaquizafop + imazethapyr mixture at 53+80 g/ha followed by propaquizafop + imazethapyr mixture at 56+85 g/ha, propaquizafop (75 g/ha), propaquizafop + imazethapyr (50+75 g/ha), propaquizafop + imazethapyr (47+70 g/ha), imazethapyr (100 g/ha) and pendimethalin (1000 g/ha). Weed management index (WMI), agronomic management index (AMI) and integrated weed management index (IWMI) were highest under propaquizafop + imazethapyr mixture applied at 53+80 g/ha followed by propaquizafop + imazethapyr mixture applied at 56+85 g/ha and hand weeding twice at 20 & 40 DAS.
