Performance evaluation of modified power weeder for dry field condition

Abstract

An experiment was conducted to evaluate the field performance of modified power weeder for dry field condition were carried out in department of Department of Farm Machinery and Power Engineering, IGKV, Raipur (C.G.). Various parameters such as effective working depth, weeding efficiency and field capacity of the weeder were considered during the test. The highest field efficiency was obtained for modified power weeder in 8 blade (75.07 per cent) followed by 6 blade (70.35%) and 4 blade (65.15%). The effective field capacity of 0.033, 0.031, and 0.032 ha/hr respectively observed for eight, Six and four blade of modified power weeder. The maximum value of cost of operation was found for modified weeder 1800/ha.
