Author(s): Shubham Pandey, AK Verma and Animesh Chandravanshi
Abstract: Weed control is important factor on crop growth and yield. There are different weed control method of rice cultivation for effective growth and yield. Mechanical weed control is helps to reduce the drudgery involved in manual weeding, it kills the weeds and also keeps the soil surface have moisture absorption capacity and loose soil aeration. Cost of labour are too high and availability is limited and therefore development of suitable mechanized weed control method is imperative. Power weeders are one step towards the standardization of practices, it has different variable rotational speed as per the need, having direction of movements, and it able to go one field to another. The purpose of power weeder is to kill weeds, minimum damages done to rice plants, cost effectiveness, low weight and easy to operate. The single row power weeder has less time consuming and significantly improves weeding efficiency as well as the quality of weeding. An experiment was conducted to trial the power weeder and its comparison against number of weeding with chemical weeding operation at 15 DAT, 25 DAT and at 35 DAT in Research farm, IGKV, Raipur. The test was carried out to assess the mechanical performance of the power weeder on the basis of number of weeding operation done by male and female workers. On comparison of male and female workers, male workers were more efficient than female worker. The actual field capacity of power weeder operated by male worker found as 0.05 ha/h with weeding efficiency of 80.95% and operated by female workers was 0.047 ha/h and 80.5% respectively. The operational speed of power weeder by male workers (i.e. 0.7 m/s) was more than the female workers (0.64 m/s). The grain yield with 3 weeding operation by single row power weeder was significantly high in comparison with other methods (viz. chemical weeding, 2 weeding, single weeding) as 48.74 qt/ha. Hence 3 weeding operation at 15, 25 and 35 DAT is economical for better production.
