However, tillage-intensive stalk destruction methods (SDMs) can degrade southeastern soils, but a cover crop may provide short-term benefits and reduce CLRDV incidence. Therefore, we examined three SDMs (Tillage, Pull, Mow) across two cover crop levels (no cover and rye [<i>Secale cereale</i> L.]/clover [<i>Trifolium incarnatum</i> L.] mixture) and two cotton varieties to determine how cotton growth, soil penetration resistance (PR), and two CLRDV incidence sample times (pre-harvest and post-harvest) were affected across six environments during the 2021 and 2022 growing seasons. None of the SDMs affected any factors examined in this experiment, except soil PR and cotton yield. The Pull and Mow SDMs both increased soil PR compared to the Tillage SDM. An 8% yield increase (Pull &gt; Mow) was observed, but the Tillage SDM yield did not differ from Pull or Mow SDMs. The rye/clover mixture also increased soil PR. Although cotton stands were 15% greater with no cover crop, subsequent cotton yield and fiber quality were minimally affected by cover crops. The rye/clover mixture increased post-harvest CLRDV incidence, and cotton yields were equal between cover crops. Pre-harvest CLRDV incidence probability was 0.23, but post-harvest CLRDV incidence probability was 0.71.

Field trials suggest that frequent plantings of canola reduce canola yields. However, there is considerable disagreement about the magnitude and persistence of these effects. We analyze the effect of rotational practices on canola yields in Saskatchewan using over 20 years of observational data, representing 61% of canola hectares in the province. We examine how the impact of rotations varies across time, soil zone, soil moisture conditions and the distribution of yields. We regress canola yields in Saskatchewan on the share of land that was planted with particular crops in previous years, using a battery of covariates and fixed effects to address potential bias in the model. After including these fixed effects, we cannot reject the hypothesis that there is no sample selection bias. We use an unconditional quantile estimator to investigate how rotations affect different deciles of the yield distribution. Our analysis confirms that crop rotations significantly influence canola yields, albeit more modest than field trials suggest. We find a 7.5% yield reduction when canola follows canola, compared to cereals, with this penalty persisting for 4 years but diminishing in magnitude with each additional year. The adverse effects of consecutive canola plantings are more pronounced in wetter regions and at lower yield deciles. Conversely, canola yields are higher when planted after pulse crops (as opposed to after cereal crops).</p>","PeriodicalId":7522,"journal":{"name":"Agronomy Journal","volume":"117 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143121041","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 aimed to investigate nutrient uptakes in cassava under different planting dates and irrigation conditions (W). Two-year field trials were conducted in the early (ERS) and post-rainy seasons (PRS), with nutrient uptakes measured at five growth stages. Planting dates had a greater impact on nutrient uptakes, accumulation rates, nutrient harvest index (NHI), and nutrient use efficiency (NUE) than W. In the ERS, the nutrients accumulated rapidly at the early to mid-growth stages, while this occurred at the mid to late growth stages for the PRS. Nutrient uptake was higher in ERS than PRS, with W differenced only in ERS 2015. Irrigation during the mid to late growth stages increased the nutrient uptake, NHI, NUE, and yield for the ERS (2015), with less impact on the PRS.

Results indicated that LS method improved morphological and yield attributes like stem thickness, terminal panicle length and weight, grain yield, 1000-grain weight, and biological yield compared to RS and BC. Among genotypes, Line-105 showed superior performance in morphology, biomass, and yield, while UAF-Q7 had higher grain protein content. Panicle number per plant showed positive correlation with terminal panicle weight, grain yield, 1000-grain weight, and harvest index. LS also resulted in highest crop growth rate and grain quality.

In both cropping seasons, the combined use of biochar and mineral fertilizer significantly increased the gross margin of paddy rice farming compared to the sole application of fertilizer.

The interplay between soil P, K, Ca, and Mg, along with harvest timing, can affect the availability and uptake of P and K, leading to varied yield responses. Field research was conducted at the University of Wyoming James C. Hageman Sustainable Agriculture Research and Extension Center at Lingle, WY, to investigate this complex interaction and its impact on alfalfa production from 2019 to 2021. Treatments included (i) 18 selected combinations (kg ha⁻¹) of three levels of P (0, 34, and 67 P₂O₅), three levels of K (0, 168, and 336 K₂O), two levels of Ca (0 and 560 CaO), and two levels of Mg (0 and 56 MgO); and (ii) two harvest schedules (early harvest, late bud to early [10%] bloom; late harvest, 7–10 days after early harvest [∼100% bloom]). Treatments were factorially (18 × 2) arranged in randomized complete blocks with three replications. Under low levels of soil Ca and Mg, the 67 P₂O₅ and 336 K₂O (kg ha⁻¹ year⁻¹) treatment produced the highest early harvest yield responses, while the 34 P₂O₅ and 336 K₂O (kg ha⁻¹ year⁻¹) treatment excelled in late harvest yield. Alfalfa fertilized with 67 P₂O₅ and 336 K₂O (kg ha⁻¹ year⁻¹) consistently achieved significant late harvest yield response in soils with high levels of Ca and Mg, leading to profitable forage production. Similar trends in P and K uptake were observed, indicating that fertilizing alfalfa with P and K can enhance productivity and profits even in soils rich in K, Ca, and Mg levels.
