Special conditions, including background clutter, occlusion, and varying sunlight, affect the accuracy of crop detection and counting. To determine the most suitable algorithms for this yield estimation context, we herein establish a public multi-object tracking (MOT) dataset for tomato cluster counts, while evaluating and comparing state-of-the-art target detection and MOT-based algorithms. The evaluated detectors consist of YOLOv8 and RT-DETR, which represent algorithms that achieve a balance between accuracy and speed. The tracking algorithms included state-of-the-art methodologies such as SORT, DeepSort, ByteTrack, and BotSort. Initially, the performance of the detectors was rigorously evaluated, followed by a comprehensive assessment of the four tracking algorithms within a multi-target tracking database tailored for this research and structured in the MOT context. The findings reveal that YOLOv8 and RT-DETR achieve 93.6% and 94.9% results at mAP@75, respectively, with RT-DETR exhibiting fewer false detections. When combined with the RT-DETR detector, the ByteTrack-based algorithm registers the highest counting accuracy at 95.5%, whereas BotSort achieves the highest MOTA score with 84.6%. Notably, the trackers without the ReID module (i.e., SORT and ByteTrack) demonstrate greater adaptability to frame rate variations in the test videos. At a 30-fps frame rate, the incorporation of ReID modules in DeepSort and BotSort algorithms significantly enhances the MOTA metric. Looking ahead, we plan to leverage these algorithms into an autonomous inspection platform that aims to estimate crop yield in real-time.</div></div>","PeriodicalId":53443,"journal":{"name":"Information Processing in Agriculture","volume":"12 4","pages":"Pages 445-455"},"PeriodicalIF":7.4,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145697898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, there is a critical need for the development of rapid, cost-effective, and reliable device for the quantitative monitoring of microorganisms in both the air and nutrient solutions of the plant factory. We have developed an integrated microfluidic biosensor that can be used to quantitatively monitor microbial levels in air and nutrient solutions by combining ATP bioluminescence. The biosensor was verified and calibrated through a standard ATP solution with <em>Bacillus subtilis</em> bacterial solution, followed by testing of the real air and nutrient solution samples from plant factories. The detection process on the microfluidic chip was automatically controlled to complete within 3 min. The consumption of ATP reaction solution and lysate for one assay was about 10 μL and 16 μL, respectively. The sensitivity of bacterial quantification was up to 6.4 × 10³ CFU mL⁻¹ with a detection range covering 4 orders of magnitude. This biosensor has been demonstrated to have similar detection accuracy with the culture counting method and enable quantitative monitoring of microorganisms in plant factory, while greatly reducing the detection cycles.</div></div>","PeriodicalId":53443,"journal":{"name":"Information Processing in Agriculture","volume":"12 4","pages":"Pages 478-486"},"PeriodicalIF":7.4,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145697845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the problem of “the curse of dimensionality”, the global optimization of greenhouse climate is usually difficult when faced with a complex dynamic model and a long cultivation period. Compared with leafy vegetables with a much simpler dynamic model and a much shorter cultivation period, the year-round tomato model usually has many more states to describe its dynamics better. To solve the year-round climate control of greenhouse tomato cultivation, a rule-based model predictive control (MPC) algorithm is raised. The innovation of this paper lies in that the setpoints of the proposed MPC algorithms are determined by the external weather and the month-averaged predictions of the tomato price. With the greenhouse climate – tomato growth dynamic model and the economic performance index, different MPC algorithms are compared with the traditional on/off control algorithm and the open field cultivation. Quantified results of yield, cost, and profit are obtained with the weather data and market data collected in Beijing. Findings of this paper showed that the year-round greenhouse tomato cultivation in Beijing is hardly profitable with the tomato price sold as an open field product (XFD price). With the tomato price sold as a high-tech greenhouse product (JD price), the higher yield guarantees a higher profit. Moreover, the simple emphasis on energy minimization cannot even guarantee a higher yield than that in the open field.

Our proposed approach was conducted in the following steps: data collection; data preprocessing; predictive model building; and model evaluation. The data correspond to three crop seasons, namely those of 2019, 2020, and 2021. Each data line corresponds to a plot with the percentage of a determined caliber at the end of a crop season.
