This study examined the effects of irrigation and fertigation on potato growth and yield using a subsurface drip system consisting of a pipe buried 40 cm underground. The water required for fertigation was 243 mm ha−1. Fertigation treatments with water were applied as topdressing through the subsurface drip system with potassium (K) fertilizer concentrations of I (only applied irrigation), K 20, K 50, and K 70 kg ha−1. Plants fertigated with 50 kg ha−1 (K50) absorbed the most potassium. Absorption did not increase with higher potassium levels; instead, potassium accumulated in the residual soil, linked to the soil's cation exchange capacity. Although potato growth was not significantly different among K treatments, it was highest in the K50 treatment. Yield was also highest with K50 and did not increase with >50 kg ha−1 of potassium. Subsurface drip irrigation had the most substantial impact on yield. While irrigation remained influential during fertigation, its effect diminished as fertigation effectiveness increased up to 50 kg ha−1 of potassium. Irrigation alone increased yield by 32.2% compared with the control, while K50 fertigation increased yield by 56.7%. Overall, this study demonstrates that subsurface drip fertigation with potassium optimizes potato yield, offering a sustainable approach for resource management in agriculture.","PeriodicalId":7522,"journal":{"name":"Agronomy Journal","volume":"117 3","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agj2.70104","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144315246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to wet weather in the fall and late-maturing soybean [Glycine max (L.) Merr.] varieties, wheat is often planted after the optimum time. To mitigate yield losses due to late planting, a higher seeding rate may be necessary. Objectives of this research were to (a) assess the main and interaction effects of planting date and seeding rate on soft red winter wheat grain yield, and (b) determine the agronomic and economic optimum seeding rates (AOSR and EOSR, respectively) of wheat based on the planting date. An experiment was established during two growing seasons at two locations in Ohio with five wheat planting date and five seeding rate treatments ranging from 1.24 to 6.18 million seeds ha−1. Average AOSR for early and timely planted wheat was 2.69 million seeds ha−1. For wheat planted approximately 4 weeks of the fly-free date and beyond that time frame, average AOSRs were 3.12 and 4.39 million seeds ha−1, respectively. The EOSRs for the same three-time frames were 2.10, 3.00, and 4.37 million seeds ha−1, respectively. Results also indicated a lower yield penalty for late-planted wheat in Ohio than previously observed, which may be due to mild winters and the favorable conditions for kernel development and grain fill during late spring and early summer.","PeriodicalId":7522,"journal":{"name":"Agronomy Journal","volume":"117 3","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agj2.70099","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144292737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Field studies were conducted in Atlantic Canada over two seasons to model buckwheat biomass production and viable seed yield as a function of planting and termination time with the goal of providing a framework to maximize biomass production while minimizing seed return, termed the critical period of cover crop management. The model demonstrated that maximum buckwheat total (979 g m−2) and vegetative (565 g m−2) biomass production could be attained when planted by 2 and 3 growing degree days base 5 (GDD5) accumulation and grown for 1680 and 2110 GDD5, respectively. Viable seed production rapidly increased with earlier planting dates and later termination dates up to a maximum of 3653 and 5974 seeds m−2, respectively. Viable seed production could be minimized to 25% of the total if terminated by 696 GDD5 or sown after 861 GDD5 had accumulated. Values below this threshold could not be modeled in the termination study.

In South Africa's Swartland region, integrating cover crops into crop rotations is increasingly popular due to their multiple benefits for cropping systems. However, there is a paucity of information on how to manage cover crops for weed suppression, in particular for herbicide-resistant ryegrass (Lolium spp.), which is a major challenge to crop production in the region. This knowledge gap leaves farmers without the necessary insights to formulate effective weed management decisions. This study tested two cover crop mixtures (cereal-based and legume-based) and three termination methods (grazed, cut and utilized as hay, and rolled). Weed seedbank counts taken before sowing the cover crop and before sowing the subsequent crop (1 year later) were used to evaluate treatment effects. Neither cover crop selection, termination method, nor their interaction affected the overall weed seed abundance. A cereal-based cover crop mixture was better at suppressing Lolium spp. abundance than a legume-based cover crop mixture (p < 0.05). There was no interaction between the cover crop mixture and termination method (p > 0.05). We found some evidence that using grazing as a termination method could result in a lower Lolium spp. abundance. However, using cover crops as hay or grazing has the additional benefit of improving fodder flow to support income from livestock.","PeriodicalId":7522,"journal":{"name":"Agronomy Journal","volume":"117 3","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agj2.70091","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144273138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, mixtures of alfalfa and ribwort plantain (Plantago lanceolata L.) had agronomic advantages for forage accumulation compared to corresponding mixtures of alfalfa and a grass species (meadow fescue [Festuca pratensis Hudson]). The ribwort plantain and alfalfa mixtures accumulated twice as much forage as the reference mixtures with meadow fescue. Most of the forage accumulation was accounted for ribwort plantain due to poor initial alfalfa development. Ribwort plantain suppressed alfalfa and all weed species from as early as July and continued increasing forage accumulation until early autumn. At the same time, ribwort plantain contributed more than meadow fescue to a reduction in NO3-N. Significantly lower NO3-N shares in the soil were observed, on average, in mixtures with ribwort plantain and alfalfa in the 0.6- to 1.2-m soil depths in autumn. Due to the inhibition of nitrification by ribwort plantain, NH4-N was present in the soil solution of the sandy soil at the trial site to a greater extent in autumn compared to alfalfa and the mixtures with meadow fescue. Due to the highly competitive power of ribwort plantain, it should only be sown in mixtures with alfalfa at seed rates of 100 germinating seeds m−2.","PeriodicalId":7522,"journal":{"name":"Agronomy Journal","volume":"117 3","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agj2.70098","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144264361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study, conducted from fall 2018 to fall 2023 near Marianna, AR, evaluated four IWM practices in a large-plot, fixed-plot factorial design: zero tolerance for weed seed rain, soil inversion deep tillage every third year in the fall, a preplant terminated cereal rye cover crop, and dicamba-resistant cotton technology. Long-term economic impacts were assessed using the 5-year average cost-adjusted yield, with the base program (excluding all IWM practices) serving as the control. Zero tolerance did not influence cotton yield and, due to a significant decline in hand hoeing time over time, had no adverse effect on economic outcomes. Most IWM combinations produced cotton yield comparable to the base program. However, the deep tillage–dicamba combination resulted in a 9% reduction. When costs were incorporated, cost-adjusted yields for the all-present, dicamba alone, and deep tillage–dicamba combinations were 5%–8% lower than the base program. Integration of a cover crop, except when combined with both deep tillage and dicamba, consistently resulted in cost-adjusted yield similar to the base program. While the progressive reduction in labor costs over time enhances zero tolerance practice's practicality as a foundational element within long-term IWM systems, the evaluated IWM practices, whether implemented individually or in combination, generally did not affect cotton yields, and many combinations, including those up to triplet levels, imposed no long-term economic burden.","PeriodicalId":7522,"journal":{"name":"Agronomy Journal","volume":"117 3","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agj2.70101","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144273139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current deep learning methods often face issues like limited scenario variations, insufficient image samples, and low detection accuracy. Furthermore, weeds and crops vary in shape and color at different growth stages, complicating detection further. To address these issues, we propose a high-precision identification method based on You Only Look Once (YOLO-D) model, for sugar beet (Beta vulgaris) and weeds at different growth stages. The model uses the FasterNet-S backbone to improve feature expression capability and receptor field coverage while maintaining high detection speed. It also introduces the C2F module, incorporating more residual connections to enhance gradient flow within the network structure. An efficient decoupling head is incorporated, reducing computational costs and achieving lower inference latency. The Lincoln beet dataset was used for training and evaluation. Compared to existing studies, the proposed YOLO-D model achieves an overall mean average precision (mAP) improvement of 3.3%, reaching 75.8%. The mAP for sugar beet increases by 1.6%, reaching 87.3%, and the mAP for weeds increases by 5.1%, reaching 64.4%.

This study aimed to explore factors affecting rice yield and quality using the Bayesian approach along with the economic feasibility of Si fertilization. On-farm experimentation was conducted over 3 years (2020–2022) across 169 fields with varying nitrogen (N) fertilization rates (48–75 kg N ha−1) in Gero City, Japan. The yield and protein content of rice were measured using commercial yield monitors, and soil properties such as mineralizable N and available Si were chemically analyzed. A Bayesian linear regression model was employed to explore the impact of multiple factors on rice yield and quality. The results revealed substantial field-level yield variability, with expected deviation ranging from −194 to 742 kg ha−1, and seasonal differences, with the highest yield observed in the third year. However, high N applications reduced rice grain quality by increasing protein content by an average of 0.34% without increasing yield. Furthermore, single-season Si fertilization showed a consistently low probability of profit, even under favorable conditions. Therefore, it might be necessary to explore the long-term effect of Si multi-seasonal applications on yield and profitability. The Bayesian approach provided a probabilistic evaluation of yield variability and economic feasibility, offering valuable insights for optimizing Si fertilization strategies in rice production.","PeriodicalId":7522,"journal":{"name":"Agronomy Journal","volume":"117 3","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agj2.70093","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144237293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These challenges can be mitigated by developing climate-resilient and biofortified crop varieties. A biofortification strategy focused on developing cultivars enriched in essential micronutrients is one of the most promising and effective approaches to addressing nutrient deficiencies in the context of a changing climate. Current efforts by scientists around the globe are aimed at bio-fortifying crops to meet present and future nutritional security needs. The grain fortification with enhanced mineral content in the seed endosperm/cotyledon depends on several factors: the nutritional status of the soil, the bioavailability of minerals in the rhizosphere, and, more specifically, the plant's ability to efficiently uptake and transport these nutrients to the sink organs. Microorganisms play a critical role in this process by improving soil health and facilitating the breakdown of trace elements through various biogeochemical cycles. In particular, plant growth-promoting (PGP) microbes, primarily actinomycetes, enhance bioavailability of minerals to crop plants, thereby improving seed mineral content. Emerging technologies and research innovations can combat global hidden hunger, and ensure nutritional security worldwide, even amidst the challenges posed by climate change. This review highlights the importance of biofortification, addresses the imminent challenges, and suggests actionable solutions. Additionally, it explores the combination of traditional agricultural practices with modern approaches to enhance nutritional quality of crops, thus contributing to a sustainable and secure food system for the future.","PeriodicalId":7522,"journal":{"name":"Agronomy Journal","volume":"117 3","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144220260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
