Answer (2)
Timely weed control enhances crop yields, reduces pest and disease infestations, minimizes competition, and improves produce quality. In Kenya, collective land tenure systems include group ranches and settlement schemes. The Economic Injury Level (EIL) determines the cost-effective point for pest control, while shifting cultivation features temporary farming, slash-and-burn practices, and is often found in low-density populations. ;
