“…Nath, et al [12], the result in this work showed that the manual reaping system is more concerned with postharvest losses (3.09%) than the semi-mechanized and mechanised harvesting systems, which both save time, labor, and money. Also, Nambi, et al [13], they study emphasizes the significance of combine harvesters; however, additional research is needed to explore the detailed potential of combine harvesters in other locations using large and small combine harvesters under various cropping conditions.…”

This study aims to obtain rice from paddy rice and determine the capacity of the threshing machine that does such separation. The research question is how to convert the paddy rice into rice, then how to use the rice husk left the paddy rice, and its ground rice by-product while mixing the paddy rice of several people. Our research method is separating the rice, rice husk, and ground rice using several mathematical equations to find the value of paddy rice, rice husk, and ground rice. Finally, we will be able to distinguish between the amount of rice and the ground rice of each person simultaneously and know the capacity of the threshing machine that does the job. Some MATLAB code was utilized to validate the equations and produce the table.

“…Mechanized harvesting emerges as a viable solution for farms of various scales, both large and small. In these contexts, adopting mechanized techniques, particularly the use of combine harvesters, presents an effective means to harvest cereal crops [ 60 ]. This not only results in reduced production costs but also enhances labor productivity.…”

Reducing postharvest losses offers a significant opportunity to enhance food availability without requiring extra production resources. A substantial portion of cereal grain goes to waste annually due to a lack of science-based knowledge, unconscious handling practices, suboptimal technical efficiency, and inadequate infrastructure. This article extensively reviews losses occurring during postharvest operations across various crops, examining diverse postharvest operations in different countries. Recent advancements in postharvest technology research are thoroughly discussed. The primary obstacles and challenges hindering the adoption and implementation of postharvest technologies are also explored. The appropriate postharvest technology relies on specific factors, including the kind of crops, production locales, seasons, and existing environmental and socioeconomic conditions.

“…To measure the actual field capacity of the weeder, the machine operating period included the time needed during the weeder's turning, the operator's time, adjustment time, re-starting time, etc. It is the proportion of the machine's real average field coverage rate to the total time during operation [15] [16]. Therefore,…”

In Bangladesh, the use of machinery in agriculture production is fast rising. Researchers are developing technology to replace traditional hand weeding to manage weeds in rice fields. The present study has been taken to increase weeding efficiency and reduce the drudgery in weeding and mulching. A line-to-line distance of 20 cm, the operation is push-pull, and field operating condition at 2 -4 cm standing water (for softening the field) was the designed hypothesis. The weeder consists of a skid/float, float holder, float adjuster, main body frame, rotor, axel, bush, rotor holder, rotor holder adjuster, handle, handle griper, handle holder, handle height adjuster, nut, bolt, etc. The designed weeder was fabricated using MS sheet, MS pipe, MS flat bar, MS nut-bolt, etc. When the rotors perform back and forth, the weeder's two conical rotors with six plain blades and six serrated blades work together to uproot and bury the weeds. It also contains a 2 mm thick float assembly with a precise angle of 22 degrees. Weeds are uprooted by the weeder's blades and buried in the muddy soil. It causes topsoil disturbance and enhances aeration. The weeding efficiency and capacity of the conical weeder were 81.92% and 0.0203 ha/h respectively. With a push-pull operation, the weeder can uproot and bury the weeds in a single row at a time. The pushing force and weight of weeder were 43.42 N and 5.6 kg respectively. Farmers can use this weeder to increase their comfort and reduce the drudgery associated with weeding and mulching in their fields.
