A study was done to see how well a weed killer called imazethapyr works on chickpea plants. They tested different amounts and times of spraying the weed killer. The best results came from using imazethapyr at a high dose early on, which led to higher chickpea yield and less weeds. This method also gave the most profit compared to other treatments. So, using imazethapyr at the right time and dose can help chickpea farmers grow more crops and make more money.
