Cropping environments were categorized based on landscape relief and water supply levels: (1) rainfed hillside (HR); (2) rainfed tableland (TR); (3) tableland with “salvation irrigation” (TS); (4) tableland with linear moving irrigation (TL); (5) floodplain (FP); and (6) tableland with subsurface drip irrigation (TD). Higher water supply levels were directly correlated with increased sugarcane potential yield. The yield decay rate was inversely correlated with the water supply gradient, with FP and TD environments showing similar potential yield rates and decay, differing significantly from non-irrigated environments. Varietal differences were observed for longevity and response to water supply, emphasizing the importance of adapting and selecting genetic material for specific cropping environments.","PeriodicalId":7522,"journal":{"name":"Agronomy Journal","volume":"117 5","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144935036","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}

This 2-year field study (2021–2022) assessed the combined impact of FM and intercropping configuration on yield, water use efficiency (WUE), and nitrogen utilization in corn (Zea mays L.)–sunflower (Helianthus annuus L.) systems. Treatments included two mulching methods: no film mulching (NF) and FM, and four planting patterns: corn monoculture (C), sunflower monoculture (S), two rows of corn alternated with two rows of sunflower (C2S2), and two rows of corn alternated with four rows of sunflower (C2S4). FM significantly improved plant height, leaf area, and dry matter accumulation in both crops. It also enhanced water and nitrogen use efficiencies, particularly in the C2S2 intercropping system, where WUE increased by 97.77%–101.35% and total nitrogen by 16.14%–23.66% compared to monocropping. Kernel quality also improved under FM, with significantly higher starch, protein, and oil contents than NF. The film-mulched C2S2 system achieved the highest yield (8068.59 kg ha−1) and economic return (36,504.33 yuan ha−1), representing a 25.79% increase in productivity over monoculture. These findings suggest that combining FM with a 2:2 corn–sunflower intercropping pattern significantly enhances yield, resource use efficiency, and profitability—supporting sustainable intensification in the Guanzhong Plain.","PeriodicalId":7522,"journal":{"name":"Agronomy Journal","volume":"117 5","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927364","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}

This review summarizes 33 published experiments on the use of cover crops in cool-climate vineyards from 1999 to 2024. Overall, cover crops increased soil organic matter, reduced bulk density, and increased water-stable aggregates in the soil. In the first few years after establishment, grass cover crops depleted soil nitrogen (N) reserves, whereas leguminous cover crops enhanced them. When cover crops were present for longer durations, soil N increased along with soil carbon (C), irrespective of cover crop species. Vines often grew deeper roots to compensate for water competition, which sometimes affected vine nutrition. Vegetative growth was frequently reduced by cover crops without affecting yield, especially in wet and vigorous vineyards. However, when competition for water was strong, yields, berry number, and bunch number were often reduced. In general, the impact of cover crops on vine and yield variables decreased with vine age. This review suggests that under certain conditions cover crops can be used in grape production to improve soil structure and fertility without sacrificing grape quality and yield. However, long-term research is needed to better understand the cumulative effects of vineyard cover crops on changes to soil structure, soil nutrients, and carbohydrate storage in perennial tissues.","PeriodicalId":7522,"journal":{"name":"Agronomy Journal","volume":"117 5","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1002/agj2.70158","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927366","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}

To address this gap, a field experiment was conducted in North Gondar to evaluate the performance of six improved malt barley varieties with a focus on yield, key agronomic traits, and grain quality, using a participatory research approach. The study employed a randomized complete block design with three replications over two consecutive growing seasons. The tested varieties included Holker, HB1963, Sabine, Ibone174/03, EH1847, and Freygebse. Results revealed that critical crop traits such as days to 50% heading, days to 90% physiological maturity, effective tiller number, number of kernels per spike, grain yield, biological yield, and straw yield were significantly influenced (p < 0.05) by both variety and growing season. Significant interaction effects between variety and growing season were also observed for all traits, except plant height and number of kernels per spike (p > 0.05). Moreover, plant height and spike length were not significantly affected by varietal differences (p > 0.05). Grain quality assessments showed that all varieties, with the exception of Holker and HB1963, had protein contents within the optimal range of 9.5%–11.5% suitable for malting. Through participatory variety selection, local farmers identified EH1847 and Holker as top performers based on a range of agronomic and quality criteria. Therefore, among the evaluated varieties, EH1847 consistently excelled across seasons, demonstrating superior yield, favorable agronomic traits, and desirable grain quality.","PeriodicalId":7522,"journal":{"name":"Agronomy Journal","volume":"117 5","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1002/agj2.70161","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927293","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, seed production in zones with elevated temperatures and relative humidity can affect ultimate seed development and quality. This study explored the developmental physiology of Mississippi Purple cowpea seeds to clarify traits associated with seed quality while defining minimum safe harvest timing and vigor of mature seeds. Seeds were planted on three farms (Gainesville, FL), and plants were cultivated according to farmer-specific management practices. Developing seeds were harvested at eight intervals starting 15 days after anthesis (DAA). Evaluations of quality traits, including water relations, chlorophyll fluorescence, seed size, and germination, were performed at each harvest period. We found negligible to large farm effects on seed quality traits that depended greatly on seed production season. Nonetheless, seed moisture content, seed water potential, seed size, and germination were key traits defining a seed harvesting window. The earliest time for harvest was 35 DAA when seeds reached physiological maturity and attained maximum viability. We concluded seeds should not be harvested when moisture content is >0.30 g g−1 or water potential >−90 MPa. Seeds ≤35 DAA can germinate but may not develop into seedlings. Seeds harvested at 45 DAA exhibited high vigor with the median time (P50) for seed germination to decrease to 50%, ranging from 140 ± 3 to 174 ± 2 (mean ± SD) days.

Over 3 years, we employed core methods, including minimum-till practices and natural mineral applications, to enhance soil physical characteristics, using cover crops and mulch to enrich SOM content. We assessed chemical soil properties such as total organic carbon (TOC), labile-C (permanganate oxidizable carbon [POXC], dissolved organic carbon [DOC], NaOH-soluble fulvic acids), glomalin content, and plant productivity. Our findings revealed that minimum-till had a significant time-dependent effect, increasing surface soil TOC by 17.58%, NaOH-soluble humic acids by 40.85%, and POXC by 77.75% over 3 years. Mulch and cover crop treatments enhanced specific carbon parameters and crop production. Different methods of assessing carbon levels proved useful for tracking time-dependent changes in soil quality.

In current research, maize (Zea mays L.) and legume intercropping has been assessed not only for biomass production, but also for its potential for carbon sequestration at various elevation sites. Research trials of maize-based sole and intercropping with mungbean (Vigna radiata L.), cowpea (Vigna sinensis S.), and soybean (Glycine max L.) were performed at three elevations (1500, 1800, and 2200 m from mean sea level) with three replications in a randomized complete block Design during three consecutive years (2015–2017). Maize economic yield (MEY), maize biological yield (MBY), aboveground biomass yield (ABY), aboveground carbon sequestered (ACS), belowground carbon sequestered (BCS), total carbon sequestered (TCS), and total carbon equivalents (TCE) were computed from experimental plots of sole and intercropped maize and legumes and for cropping systems.

It is essential to fulfill the nitrogen (N) requirements to attain high yield potentials, provided that a recommended optimum N rate (ONR) is both economically and environmentally sustainable. The agronomic and economic ONR (AONR and EONR, respectively) and the yield-goal-based N rate (YGR) are benchmarks used in N recommendation systems. However, edaphoclimatic conditions, crop physiology, and field crop history might influence ONR estimations. This study aimed to compare AONR, EONR, and YGR in 3 years (2022, 2023, and 2024) and two fields. Response curves were created for different groupings: field-year (six levels), year (with fields combined, three levels), field (with years combined, two levels), and complete dataset (one level). The AONR, EONR, and YGR were calculated from the best model for each level of grouping and ranged between 229 and 412, 229 and 351, and 219 and 318 kg ha−1, respectively. Eight out of 12 levels were best regressed to linear-plateau curves, while four followed quadratic curves. The EONR was either lower or equal to the AONR. The YGR did not adequately detect field-year variability, meaning that growers might over- or under-fertilize corn in Florida, applying 32 kg ha−1 more to 46 kg ha−1 less N than the EONR. These findings raise the question of which is the best approach to determine an ONR in Florida: regression or arithmetic.

Planting dates evaluated included early April, mid- to late April, mid-May, and mid-June. Maturity groups evaluated included III, IV, and V. The seed treatments included in this study represent a range of the commercially available fungicide seed treatments and fluctuated between 2019 and 2020 but were compared to a nontreated control in each environment. Fungicide seed treatment impact on soybean stand was variable across environments, with stand protection from using treated seed in one environment of 12,146 plants ha−1 at the earliest planting date (early April). Soybean maturity group also impacted the value of a fungicide seed treatment, which is likely a result of differing varietal resistance packages to seedling diseases among the soybean maturity groups used in this study. Fungicide seed treatments provided considerable yield protection at planting dates in mid-May and earlier. Results across these environments emphasize the variability in which fungicide seed treatment can protect soybean stand and yield across planting dates and environments, and producers should consider planting date and environmental conditions when making decisions about this input.","PeriodicalId":7522,"journal":{"name":"Agronomy Journal","volume":"117 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1002/agj2.70142","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144853731","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}
