摘要

Currently, manual weeding is done in garlic, with hand tools like Khurpi or hand pulling which is a cumbersome operation. The cost of weeding by manual method alone accounts for more than one-fourth of the total cultivation cost in garlic. Tractor drawn mechanical weeding helps reduce time consumption and drudgery of manual weeding in non-herbicidal growing systems. A soil bin study with laboratory model weeder was carried out to investigate the effect of number of tines (soil working tool), depth ofoperation and forward speed of simulated weeds on weed control factor (WCF). The experimental study showed that the number of tines, depth of operation and forward speed significantly affected the WCF and it increased with an increase of all the three parameters. Three tines operated at 75 mm depth at 3 km/h speed gave the maximum value of WCF. Depth of operation of tine was the predominant factor influencing the WCF. Based on the soil bin investigation, tractor-drawn weeder was developed with multipleflexible round tines that vibrate perpendicular to the tractor direction to remove weeds from the soil. Developed weeder was evaluated for managing weeds in garlic crop grown on raised beds. The effective field capacity and field efficiency were observed as 0.18 ha/h and 76.62%, respectively, at forward speed of 2 km/h. The plant damage and weeding efficiency was observed as 1.61 and 68.64%, respectively. The cost saving due to usage of the developed weeder, in comparison with the existing manual weeding, was 51.3%. The machine has potential for adoption by farmers growing garlic on raised beds.
