Experimental study of the haulm-cutting moduleof root crop harvesting machines

Viktor Baranovsky, Maria Pankiv, Roman Komar, Vitalii Pankiv, Yevhen Berezhenko

Res. Agr. Eng., 2026, 72(3):155-166 | DOI: 10.17221/172/2025-RAE  

Reducing the energy consumption during the harvesting of large root crops (such as sugar and fodder beets, and chicory), which are used to produce food and industrial products, is a priority issue for improving the efficiency of production processes in agro-industrial enterprises. One approach to addressing this issue involves reducing the energy expenditures by the working elements of the haulm removal module in root crop harvesters by implementing a single-phase harvesting method. An improved method for haulm cutting is proposed, whereby the cut haulm is deposited in the field between two adjacent dividing discs located in the inter-row space...

Effect of the probe diameter, cultivar and post-harvest storage on the cocoa pod firmness and deformation energyOriginal Paper

Randy Amuaku, Francis Kumi, Godwin Kwasi Amanor, Enoch Asante, Gladys Pepertual Awudi

Res. Agr. Eng., 2026, 72(3):167-180 | DOI: 10.17221/54/2026-RAE  

The mechanical characterisation of cocoa pods is essential for improving the post-harvest handling, mechanised processing, and objective quality assessment. This study investigated the effects of the probe diameter, cultivar, and post-harvest storage duration on the cocoa pod firmness, deformation energy, and yield stress using penetration testing. Three cultivars (Amazonia, Forastero and Amelonado) were evaluated under controlled conditions (27 ± 2 °C; 70 ± 5% RH) over 8 days using probe diameters of 3.5, 8 and 11 mm. The results showed that the probe diameter significantly influenced the measured firmness, with smaller probes producing...

Enhancing the performance of lotus seed kernel and shell sorting after dehulling: A real-time approach based on deep learning and image processing (YOLOv8)Original Paper

Dinh-Tu Nguyen, Huu-Phat Tran, Duc-Tin Le, Hoai-Tan Nguyen, Thanh-Thuong Huynh

Res. Agr. Eng., 2026, 72(3):181-194 | DOI: 10.17221/29/2026-RAE  

Lotus seeds represent a high-value agricultural commodity, widely utilised in the food and pharmaceutical industries for their nutritional and medicinal benefits. However, post-harvest processing, specifically the removal of shells, often relies on manual labour or rudimentary equipment that results in low productivity. This study proposes a computer vision system based on the YOLOv8 deep learning framework to automate and enhance the efficiency of post-decortication sorting. The model is designed to detect and classify three distinct components: unshelled seeds, kernels, and shell fragments. Based on these predictions, the system controls pneumatic...

Vetiver grass for road slope protection through soil erosion and runoff reduction in a haor area of the Sunamganj districtOriginal Paper

Tahmina Akter, Saumik Acharya, Sayed Jaber Al-Hossain, Golam Kibria Robbani

Res. Agr. Eng., 2026, 72(3):195-203 | DOI: 10.17221/124/2025-RAE  

Erosion control on slopes and embankments is a global concern, with vetiver planting emerging as an effective solution. This study investigated vetiver grass as a potential alternative for reducing runoff and soil erosion in protecting road embankments. In a small-scale model on a 1 V : 2 H slope, simulated rainfall was applied through a perforated sheet. The runoff was collected, and the eroded soil samples were dried using the sand bath method. The runoff and soil loss were compared with and without vetiver grass. The results showed that the vetiver grass significantly reduced the soil erosion, preventing about 87% more soil loss than the bare...

A semi-automatic prototype machine for splitting and endosperm extraction of Nypa fruticans: Design and experimental evaluationOriginal Paper

Thanh Thuong Huynh, Dao Khanh Danh Dinh, Van Huu Bui

Res. Agr. Eng., 2026, 72(3):204-216 | DOI: 10.17221/44/2026-RAE  

Nypa fruticans is a mangrove palm whose immature fruit endosperm is widely consumed, but harvesting and extraction are still largely performed manual, resulting in low productivity and inconsistent quality. This study presents the design and experimental evaluation of a semi-automatic prototype machine for splitting nipa palm fruits and extracting the endosperm. The machine integrates a roller–blade mechanism for fruit splitting with a suction-based endosperm extraction system. To determine suitable operating conditions, the Taguchi design of experiments was applied using two independent L9 orthogonal arrays for the splitting and...

Characteristics of tiger nut milk pretreated with magnetic fieldShort Communication

Michael Mayokun Odewole, Tofunmi Oreoluwa Abodunrin, Gbolahan Olumide Ajayi, Sa'ad Olansile Yusuf

Res. Agr. Eng., 2026, 72(3):217-220 | DOI: 10.17221/50/2026-RAE  

The thermal pre-treatment of tiger nut milk (TNM) via pasteurisation may have adverse effect on its quality characteristics. The use of a magnetic field (MF) to pre-treat TNM is a promising non-thermal method. This study investigated the effects of an MF pre-treatment on three (3) selected quality characteristics of TNM. Fresh TNM samples were pre-treated at 0.25–15.37 mT MF strength under static and pulse MFs for 10 minutes. All the samples were analysed for calcium, vitamin E and the microbial load, using standard procedures. The results showed that the MF pre-treatment led to an average 10% increment under pulse MF in the calcium of...
