The validity of these tests is commonly assessed using the Type I error rate. Type I error is obtaining a false positive result. It is known that Fisher's Least Significant Difference (LSD) and Duncan tests have high Type I error rates because even a single false positive is sufficient to constitute a Type I error. For multiple comparison tests, the number of correct decisions (true positives and true negatives) is more important than the Type I error rate. Therefore, in this study, specificity and sensitivity were considered alongside the Type I error rate. Specificity refers to the true negative rate, while sensitivity refers to the true positive rate. A Monte Carlo simulation showed that the LSD and Duncan tests had relatively high Type I error rates; however, when specificity was considered, the LSD and Duncan tests correctly predicted statistically similar groups (true negative) with a mean of 97.00%, while other tests achieved 99.00%. Regarding sensitivity, the LSD and Duncan tests correctly identified statistically different groups (true positive) with a mean of 15.00%, while other tests achieved 3.00%. The true negative rate of the other tests is 1.02 times (99.00/97.00) that of LSD and Duncan. In contrast, the true positive rate of LSD and Duncan is 5.00 times (15.00/3.00) that of the other tests. Therefore, considering both specificity and sensitivity, the LSD and Duncan tests were found to be superior to others. In conclusion, these tests were shown to be more reliable.","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":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144853779","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}

Adding cover crops to corn production increases the challenge of determining optimum nitrogen (N) rates because of their impact on N cycling. We evaluated the AONR and the corn yield at the AONR following cereal rye, hairy vetch, a rye–vetch mixture, and a no-cover crop treatment in the cover crop-corn growing seasons of 2020–2021, 2021–2022, and 2022–2023 in an experiment that included six N rates (0, 45, 90, 180, 270, and 360 kg N ha−1) in Eastern Nebraska. The only consistent pattern found across years was that cover crops did not decrease the corn grain yield at the AONR, nor did they increase the AONR compared to the no-cover crop treatment. In 2021, a year with near-normal precipitation, the corn yield at the AONR and the AONR were the highest of all 3 years following cover crop treatments. In 2022, the total rainfall during the corn-growing season was approximately half of the 30-year average, decreasing yield at the AONR across treatments. In 2023, growing season total precipitation was closer to normal (86% of the 30-year average), and although there was no significant effect of cover crop treatments on the AONR, there was a decrease in yield compared to near-normal precipitation in 2021. These results highlight weather as a dominant factor driving AONR and do not support the need for higher N rates following winter cover crops.","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/agj2.70129","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144853724","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}

Red clover is a leguminous cover crop that can grow in low-radiation environments and is winter hardy. Systems with red clover have demonstrated improved corn yield and a fertilizer N equivalence but understanding these effects with inter-seeding warrants further investigation. The objectives of this study were to determine the effect of inter-seeding red clover on (i) plant-available N during and after red clover decomposition, (ii) optimum N rates for corn, and (iii) corn yields. The experimental design was a randomized, complete block-split plot design, with cover crop as the main plot factor (treatments with and without inter-seeded red clover) and N-rate as a split-plot factor (N-rates between 0 and 315 kg-N ha−1 in 45 kg-N ha−1 intervals). Quadratic plateau response curves with a bootstrapping technique were used to determine differences in optimum N rate among treatments. Corn yields were evaluated with or without red clover inter-seeded following the first inter-seeding year. Red clover accumulated biomass values of 50 kg ha−1 up to 300 kg ha−1 pre-termination when inter-seeded with corn at the V4–V5 growth stage without detriment to yield. Corn yield was improved with clover treatments in one of four site years tested, resulting in a (15–17 kg ha−1) lower N requirement that year. Overall, our results indicate that inter-seeding red clover into continuous corn did not provide an agronomically meaningful nitrogen fertilizer equivalence to the cropping system.","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/agj2.70133","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144853780","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}

The present study investigated impact of foliar applications of Carrabiitol, a patented oligosaccharide polyol, on soybean growth and yield across the diverse agro-ecological zones of Himachal Pradesh, India. The study encompassed three ecological zones: Zone I (Akrot), a sub-montane low-hill subtropical zone; Zone II (Palampur), a mid-hill sub humid zone and Zone III (Awarna), high-hill temperate wet zone. Treatments consisted of four Carrabiitol application rates: T1 (50 g ha−1), T2 (75 g ha−1), T3 (125 g ha−1), and T4, the control (0 g ha−1). Soybean growth and yield responses were evaluated based on plant height, number of branches per plant, number of pods per plant, number of seeds per pod, seed weight, seed yield, straw yield, and harvest index. Notably, soybean response to the application of 75 and 125 g Carrabiitol ha−1 outperformed the untreated control treatment in all climate zones. The soybean response to Carrabiitol was in the sub-montane low-hill subtropical zone (Zone II), and the most effective treatment was Carrabiitol at 125 g ha−1. In Zone I, where temperatures were higher and rainfall was lower compared to Zone II, this treatment increased soybean seed yield by 54.3%. These findings suggest that Carrabiitol can help mitigate the adverse impact of unfavorable climatic conditions.","PeriodicalId":7522,"journal":{"name":"Agronomy Journal","volume":"117 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1002/agj2.70136","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144832855","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}

The Green Revolution gene sd1 has long been central to modern rice (Oryza sativa) breeding, but overreliance on a single gene risks genetic diversity, sustainability, and yield under changing environmental conditions. Recent efforts across various crops have identified new dwarfing genes and regulatory networks as promising alternatives. In rice, key gibberellin (GA)- and brassinosteroid (BR)-related genes such as D18, EUI1, D1, D11, and D61 have been identified, alongside SlGAI, SlBRI1, SlRR6, and SlARF5 in tomato (Solanum lycopersicum). Hormonal pathways involving GA, BR, and auxin are major determinants of stem elongation and internode architecture, with cross-regulatory components such as DELLA, PIFs, and BZR1 central to the shade avoidance response (SAS). This review explores the genetic, physiological, and molecular mechanisms of dwarfism in monocots and dicots, focusing on recent findings in rice, tomato, and other crops. We highlight advances in understanding how cell elongation, cell wall biosynthesis, and hormone interactions regulate culm length and structural strength. Novel mutants that preserve yield and fruit size while minimizing height offer potential for smart farming and dense planting systems. We also examine trade-offs such as reduced biomass or fertility and stress the need to balance compactness with productivity. Future directions include high-throughput phenotyping, functional validation, and multi-environment testing to enable deployment of diverse dwarfing alleles in breeding.","PeriodicalId":7522,"journal":{"name":"Agronomy Journal","volume":"117 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144814660","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 study investigated the profitability and the associated risks with the adoption of precision irrigation scheduling methods for cotton (Gossypium hirsutum) production under conservation tillage. Two irrigation scheduling methods were compared with a dryland control (Control): a calendar-based checkbook method (Checkbook) and a precision irrigation method using the Smart Irrigation Cotton App (Cotton App) in Camilia, GA. The net return distributions were subsequently ranked using stochastic efficiency with respect to a function to examine the risk preferences of the irrigation methods among cotton growers. The findings revealed significant water saving, ranging from 24% to 77%, when the Cotton App was used instead of the Checkbook. Risk analysis indicated that the Cotton App was preferred over the Checkbook across all levels of producer risk aversion. The utility-weighted risk premiums for the Cotton App ranged from −$18 to $42 ha−1 when compared to the Control and from $284 to $305 ha−1 when compared to the Checkbook. The positive risk premium value of the Cotton App over the Checkbook suggests that adopting precision irrigation scheduling strategies, such as the Cotton App, could enhance profitability for cotton growers. The findings from the risk analysis provide valuable guidance to risk-averse cotton growers, enabling them to make well-informed decisions regarding the adoption of innovative methods and effectively mitigate income uncertainties while conserving water and thus promoting sustainable agricultural practices.","PeriodicalId":7522,"journal":{"name":"Agronomy Journal","volume":"117 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1002/agj2.70127","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144814532","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 has also raised interest among agricultural economists, especially production economists, in including environmental outcomes in efficiency or productivity analyses and in identifying sources of sustainable productivity growth in a reliable manner. However, such assessments at the farm level are often hindered by the lack of data with which to derive appropriate, meaningful, and relevant (social and environmental) indicators. Ignoring these data limitations, many scholars use simple indicators based, for example, on the European Union's Farm Accountancy Data Network or the Australian Agricultural and Grazing Industries Survey data that poorly reflect the actual environmental performance of farms. While the need to use environmental information is obvious, the argument of using simple indicators rather than no indicators at all has to be questioned in many cases since the estimated data will influence the outcome of the analysis. Therefore, careful attention should be given to the choice of indicators and especially to agronomic soundness.","PeriodicalId":7522,"journal":{"name":"Agronomy Journal","volume":"117 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agj2.70123","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144782259","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 the US Midwest, strong wind gusts associated with thunderstorms often cause significant stalk breakage in maize (Zea mays L.) fields. This study investigated whether crop insurance adjustment tables continue to be accurate when adjusting for maize yield after stalk breakage has occurred. Two experiments were conducted to assess the effect of below-ear and above-ear stalk breakage at four levels of severity (0%, 25%, 50%, and 75%) and at three timings (V13, V17, and tassel stage [VT]). Trials spanned nine site-years across Iowa, Minnesota, and Nebraska from 2019 to 2022. Below-ear breakage results in a loss of the primary ear, while above-ear breakage reduces the size and weight of the harvestable ear. Plant density, primary and secondary ear counts, grain yield, and kernel mass were measured. The number of secondary ears was highly influenced by the damage type. When breakage occurred above the ear node, 25% damage severity resulted in a 35% increase in the number of secondary ears compared to the untreated control. When breakage occurred below the ear node, the impact was much more evident, with an 85% increase of secondary ears. On average, breakage above the ear resulted in a 9.5%, 18.6%, and 25.2% yield penalty for 25%, 50%, and 75% severity, respectively. As expected, for the same damage severity, below-ear breakage resulted in much higher yield penalties (13.3%, 32.6%, and 55.0%).
