Development and Performance Evaluation of a Two-Wheeled Power-Tiller Multi-row Weeder
Saha Kowshik Kumar,Hossain Akbar,Hoque Muhammad Arshadul,Jahan Md. Abu Hena Sarwar,Ahmed Sharif,Timsina Jagadish 한국농업기계학회 2021 바이오시스템공학 Vol.46 No.1
Purpose This study was conducted to design, construct, and test a two-wheeled power tiller multi-row weeder (MRW) for effective weed control in wheat production field and other narrow-row crops. This concept was conceived from the high cost and labour-intensive methods required for hand weeding (HW) and the restrictions in chemical weed control borne by the resource-poor smallholder farmers of South Asia. Methods An MRW was designed, fabricated, and field tested with other weeding techniques (HW using khurpi, HWusing a hand spade, weeding using a Bangladesh Agricultural Research Institute (BARI) dry land weeder, and no weeding) at the Farm Machinery and Postharvest Process Engineering Division, Bangladesh Agricultural Research Institute BARI centre in Gazipur during 2013–2014 and 2014–2015 wheat growing seasons. Results The results have shown that the MRW had a higher percentage of plant damage (4.3–4.6%) but also higher actual field capacity (0.12–0.14 ha/h), resulting in lower weeding cost than other weed control techniques. Hand weeding using a khurpi treatment had significantly (p ≤ 0.05) higher weed control efficiency but had higher weeding cost and was labour-intensive (81–93%) than all other treatments, suggesting that it may not be a feasible option for smallholder farmers. Wheat grain yield was similar (p ≤ 0.05) for all weed control methods but significantly higher than the control treatment. In spite of the higher percentage of plant damage in MRW, there was no adverse effect on achieving the desired plant population as evidenced from the grain yield data. Conclusions Results suggest good performance and significant potential of MRWbut also a need for further improvement for its wider adoption by smallholder farmers in Bangladesh and South Asia.

Design and Performance Evaluation of NPK Briquette Applicator for Small-Scale Upland Crops
Miah Md. Sumon,Rahman Md Mashiur,Hoque Muhammad Arshadul,Hossain Md. Ayub 한국농업기계학회 2022 바이오시스템공학 Vol.47 No.3
Purpose Surface broadcasting application of prilled nitrogen, phosphorus, and potassium (NPK) fertilizer by hand in small-scale upland crops is time-consuming, labor-intensive, and wastes of a significant amount of fertilizer, contributing to greenhouse gas (GHG) emissions. Methods For this, a novel hand-held applicator for subsoil placement of NPK briquette was designed, developed, and tested both in the laboratory and experimental fields to evaluate applicator performance and its impact on field crop performance. The applicator works with the four mechanisms—feeding, metering, delivery, and subsurface placement with covering. The field experiment was conducted with four application treatments (NPK briquette application by applicator and hand, prilled NPK fertilizer as same dose and standard dose as applied by farmers). Results The result showed that the applicator had the highest consistent placement of NPK briquette (no losses) during laboratory and field tests. The applicator had a field capacity of 0.039 ha/h and field efficiency of 86.6%, which resulted in better performance than other application methods. The average hole coverage was 85.6%, the depth of placement was 77 mm, and the distance between the plant and the briquette application was 96.8 mm, all of which were close to the reference value. Moreover, crop yield was higher or similar to NPK briquette application by the applicator but significantly (p≤0.05) higher than other application methods. The weight of the applicator is 1.8 kg, so farmers can efficiently operate this user-friendly applicator. Conclusion NPK briquette applicator has shown excellent performance and significant potential for accurate, consistent, and deep precision placement of NPK briquette in the crop root zone for upland crops. Furthermore, the applicator has several advantages, including lower fertilizer costs and less drudgery associated with hand placement, which encourages farmers on a small-scale upland crop production.
