Design and development of manually operated cono-weeder

Weed control is a major intercultural operation and always encountered as a different problem in Indian agriculture. It generally involves high labour requirement costly operation and is also painstaking due to non consideration of human comfort. The cono-weeder was designed and fabricated for soybean crop, and the experiment was conducted to determine its wee.Jing efficiency, field capacity and field efficiency and the performance was compared to wheel hoe and khurpi. It was found that weedling efficiency, field capacity and field efficiency of cono weeder 8 re 77.76%, 64. 10% and 76.6% respectively which is more than wheel hoe and khurpi. The total cost of cono-weeder was estimated as Rs. 156.53 which is less than wheel hoe and Khurpi. The study also revealed that the operational cost and time can be reduced by using cona-weeder.
