The researchers tested different weed control methods in chickpea fields to see which ones worked best. They used herbicides and cultural practices to control the weeds. They found that applying pendimethalin before the chickpea plants emerged, along with using Imazethapyr later on, was the most effective way to control weeds. They also discovered that combining certain herbicides gave better results than using them alone. Overall, the combination of pendimethalin and Imazethapyr was the most efficient at controlling weeds in chickpea fields.
