A manual type operated weeder was designed and developed at the workshop of the Department of Farm Machinery and Power at BCKV, Nadia district, West Bengal, India. This Study was conducted to know the design features of manually operated weeders for paddy weeding. The weeder was made of locally available materials to reduce the cost of weeding. The weeder was tested at the experimental field of the Department of Farm Machinery and Power to evaluate its functional and economical parameters. The travel speed of this type weeder is 1.3 km/h. The weeding efficiency of weeder was found 65.6% to 74.2%. The average field capacity of the weeder was observed as 0.013 ha/h. The field efficiency of this type weeder was found as 81.2%. The plant damage of this weeder was found as 2.96%. Operating cost of this type weeder is Rs. 3557.3/ha. Therefore, designed of this type weeder is the best in terms of cost of operation and it is more economical compared to other weeding operation.

“…Weeding methods in the paddy fields include manual weeding, chemical weeding such as using herbicides, mechanical weeding including weeding roller, intelligent weeding such as paddy weeding robot [6] , physical weeding such as plastic sheet mulching, biological weeding such as rice duck farming [7] , and so on. The commonly used weeding method in the world since the 1980s is chemical removal using herbicides in the paddy fields [8,9] . However, the utilization rate of herbicides is very low, with an average utilization rate of 30%.…”

Weed control in paddy fields is a worldwide problem and mechanical weeding will become a major weeding method in non-chemical weeding. A mechanical weeder was designed and tested to improve the efficiency of mechanical weeding and reduce the application of herbicides in this study. The weeding equipment is equipped with three sets of inter-row weeding parts which include ground-contoured-following pressing-grass float (GPF), weeding roller, and so on. The weeding principle of weeding part is that the weeding equipment enters the inter-row area with weeder moving forward, then the GPF overwhelms the weeds in the inter-row area to improve the probability that the weeding roller behind the GPF pressed the overwhelmed weeds into the soil. The effects of weeding methods on the plant height, grain yield and quality attributes were investigated in a two-seasonal field experiment. Three weeding methods were applied in the present study: no-weeding, chemical weeding and mechanical weeding. The results of the two-seasonal field experiment showed that the average weeding rates of mechanical weeders were 87.10% and 87.61% respectively. In both seasons, there was no significant difference among weeding methods on plant height at the early growth stage of rice after weeding, but weeding methods had significant effect on plant height at the late growth stage. The plant height of mechanical weeding was higher at the late growth stage. Weeding methods had significant effects on grain yield, grain number per panicle, seed-setting rate, 1000-grain weight and shoot dry matter accumulation (p<0.05), however there was no remarkable effect on rice quality and other attributes (p>0.05). Grain yield of mechanical weeding was significantly higher than that of no-weeding. There was no significant difference between chemical weeding and mechanical weeding. It can be concluded from the two-seasonal experiment that mechanical weeding had the same effect as chemical weeding on grain yield and rice quality.

“…Using the developed machine recorded 73% weeding efficiency and reduced the operating cost about 77.5% compared with manual weeding. Mahilang et al (2017) developed a power operated rotary weeder. The cutting unit contains 3 hubs each one containing 2 standard L-shaped blades were fitted on the rotary shaft.…”

This study aims to develop a suitable hoeing machine for the crop planted at flat and the ridged soil with ridges reforming, and evaluate it by studying some effective factors such as blades shape, kinematic indices, crop planting methods and power requirements. The experiments were carried out in the Rice Mechanization Center at Meet El Deeba, Kafr El-Sheikh Governorate. The results indicated that using the developed machine using L-shaped blade increased the weeding efficiency by about 4%, plants damage about 0.8%, operating power requirement about 1.6% in comparison with C-shaped blade. In addition increasing the kinematic index increased the weeding efficiency and also plants damage percentage using L and C-shaped blades and crop planting methods.
