Effect of Herbicidal Weed Management on Productivity and Profitability of Summer Cowpea

Background: The presence of weeds in cowpea reduced the yield to tune 60-82% depending on weed flora and density. critical period competition was 20-25 DAS. Therefore it is essential control effectively harness maximum potential crop. To manage also important determine efficacy pre post-emergence herbicides. Sequential application herbicides a short duration crop not only increases cost production but create cumbersome its application. ready mix are now becoming popular among farming community. These new need be tested for bio-efficacy effect productivity symbiotic characters cowpea. Therefore, field experiment carried out evaluate impact profitability summer (Vigna unguiculata L.) at Agronomy Main Research Farm, Odisha University Agriculture Technology, Bhubaneswar, (India) during season. Methods: laid season 2021 and2022 randomized block design (RBD) comprised eight treatment with three replications. Standard procedures were followed observations statistical analysis data. Result: experimental results revealed that pendimethalin+imazethapyr-750 g/ha significantly mixed which resulted significant increase growth yield. Ready pendimethalin + imazethapyr 750 registered highest benefit ratio.
