Outbreaks have reduced sugar yields, and breeding for tolerant varieties has not been conducted in Japan. This study marks the first step toward developing VY-tolerant varieties by testing three hypotheses: (1) leaf yellowing can be induced by artificial inoculation, (2) tolerance varies among breeding materials, and (3) differences in tolerance to yellowing disease can be evaluated. From 2017 to 2020, four sugar beet materials were grown in inoculated and uninoculated plots and assessed using two methods: the yellowing index (YI), scored as 0–3, and the yellowing area (YA), calculated from digital images. Triple antibody sandwich–enzyme-linked immunosorbent assay confirmed that all BLYV-inoculated plants were infected and exhibited marked yellowing compared with uninoculated plants. Analysis of variance (ANOVA) applied to YI and YA data revealed that inoculation significantly influenced yellowing, symptoms progressed over time, and yellowing progression varied by material. Additionally, YI and YA were significantly correlated, with a Spearman correlation coefficient (<i>r</i>s) of 0.718. The significant correlations between YI or YA values and sugar yield loss (<i>r</i>s = 0.86–0.87) and root weight loss (<i>r</i>s = 0.80–0.83), but no significant correlation with Brix loss (<i>r</i>s = 0.32–0.46). These results validate the tested methods for evaluating BLYV tolerance and highlight the potential for breeding sugar beet varieties with enhanced tolerance.

This shrinkage creates cracks that may measure &gt;10 cm in width and &gt;1 m in depth when the soil is dry. Current numerical models are not able to accurately represent these dynamic pore characteristics and often soil shrink-swell processes are not taken into consideration at all. In order to incorporate these dynamic characteristics into numerical models, it is necessary to first quantify changes in pore characteristics—pore number, connectivity, size distribution, and tortuosity—that accompany changes in soil water content. X-ray computed tomography (CT) is a technology used to visualize the internal structure of an object and can be used to observe and quantify pore spaces in a soil sample. The goal of this project was to improve our understanding of dynamic porosity in shrink-swell soil by using X-ray CT scanning to quantify pore space characteristics in shrink-swell soils at two soil water contents: after wetting and oven-dried. Three intact soil cores were wetted, scanned using X-ray CT, then dried and scanned again. ImageJ and MATLAB software were used for image processing and analysis of structural changes within the cores. Our results show a statistically significant difference in pore network characteristics between wet and dried cores, with higher porosity, smaller pores, lower connectivity, and higher tortuosity values for the wet cores. These results have important implications for numerical simulations of soil water flow, which often disregard porosity dynamics due to shrinkage.</p>","PeriodicalId":7567,"journal":{"name":"Agrosystems, Geosciences & Environment","volume":"8 3","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1002/agg2.70196","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144894340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these concerns, two on-farm trials using split-plot design determine the effects of planting methods (mechanical vs. manual) and fungicide treatments (Priaxor, Provysol, Quilt Xcel) on sugarcane growth and yield. Data collected included seed cane rate, tiller dynamics, physiological parameters, plant height, gap analysis, and yield components across two growing seasons. Results showed mechanical planting required nearly four times higher rate of seed cane compared to manual planting. Mechanical planting reduced tiller count at early growth stage, but it was compensated at the later stage with no significant difference compared to the manual planting at the later growth stage. Significant interaction between planting methods and fungicide treatments in one of the two trials showed that fungicide application significantly improved plant height (by about 18%), number of millable stalks (by over 30%), and cane yield (by approximately 40%) in mechanical planting but not in manual planting. The physiological parameters, such as soil plant analysis development and leaf area index, were not influenced by planting methods or fungicide treatments.
