Elevated CO2 often increases weed growth, exacerbating problems including impacts on crop yield and weed control. How rising CO2 affects herbicide-resistant weeds remains largely unknown. Palmer amaranth (Amaranthus palmeri) populations resistant to or susceptible to glyphosate were exposed to ambient or elevated (ambient +200 μmol mol−1) concentrations of CO2 in open-top chambers. Two weeks after CO2 exposure, each population was sprayed with glyphosate at 0, 0.5×, 1.0×, or 1.5× the label rate. Afterwards, CO2 exposure continued for an additional two weeks when visual herbicide injury and leaf gas exchange were assessed. Plants were harvested for determination of treatment effects on growth. Elevated CO2 had little effect on most variables except for decreasing stomatal conductance (~25.5%) and increasing water use efficiency (~49.2%). Glyphosate resistant plants showed decreased height (9.8%) and damage (~56.4%) and increased root dry weight (12.1%), photosynthesis (~41.2%), stomatal conductance (~63.3%), and water use efficiency (~32.0%). In general, increasing rates of glyphosate decreased growth and gas exchange variables, which was frequently only seen in the susceptible ecotype.

Urease inhibitors (UIs) and nitrification inhibitors (Nis) can mitigate the release of N and reduce the harmful effects of excessive N concentrations. However, the effect of these inhibitors on the soil nutrient-microbial activity-plant growth system is unknown in peanut. The purpose of this study was to investigate the effects and mechanism of N-(n-butyl) thiophosphoric triamide (NBPT), 3,4-dimethylpyrazole phosphate (DMPP) and sulfur-coated urea (SCU) on peanut. The results showed that comparing with urea alone, adding NBPT + DMPP inhibited the urea hydrolysis better and decreased the concentration of NH4 +-N + NO3 −-N by 20.8% in soil. Therefore, it increased the net photosynthetic rate, promoted the development of roots even the absorption of N by peanut, with N use efficiency (NUE) up to 20.8%. The effect of NBPT + DMPP on microorganism was better than that of NBPT alone, which considerably impacted the structure and abundances of aonia oxidizing bacteria (AOB) but not ammonia-oxidizing archaea (AOA). Specifically, g_Nitrosospira and g_Nitrosomonas decreased by 46.9% and 2.2% respectively, and g(c) Betaproteobacteria increased. Furthermore, when combined with SCU on this basis, the overall effect was clearer.","PeriodicalId":8154,"journal":{"name":"Archives of Agronomy and Soil Science","volume":"69 1","pages":"2938 - 2955"},"PeriodicalIF":2.4,"publicationDate":"2023-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42164224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, laboratory, greenhouse, and field experiments were carried out to estimate the efficacies of SDS, S-SDS (stored at room temperature for 12 months), and H-SDS (heated at 100°C for 30 min) against plant powdery mildew. This bacterium produced hydrolases (phosphatase, protease, lysozyme, chitinase, and β-1,3-glucanase) that degrade pathogen cell components and siderophores that compete for iron with phytopathogens. The top five antimicrobial metabolites identified in SDS were pyroglutamic acid, deoxycytidine, pyrrole-2-carboxylic acid, 13-oxo-9,11-tridecadienoic acid, and 3’-amino-3’-deoxythimidine. Among them, pyroglutamic acid may play a vital role in powdery mildew control. As a result, SDS, S-SDS, and H-SDS strongly inhibited the conidial germination of Erysiphe cichoracearum and Sphaerotheca fuliginea. The application of SDS significantly increased the activity of antioxidant enzymes in crop leaves and effectively controlled tobacco and cucumber powdery mildew in the greenhouse and the field. Therefore, L. enzymogenes LE16 can effectively control powdery mildew. The underlying mechanisms may be attributed to the induction of plant systemic resistance and the production of antifungal substances.","PeriodicalId":8154,"journal":{"name":"Archives of Agronomy and Soil Science","volume":"69 1","pages":"2898 - 2910"},"PeriodicalIF":2.4,"publicationDate":"2023-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42844975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five treatments were tested: control; seed treatment with Bradyrhizobium spp. (SBr), seed treatment with Bradyrhizobium spp. + A. brasilense (SBr+Az), in-furrow treatment with Bradyrhizobium spp. (FBr), and in-furrow treatment with Bradyrhizobium spp. + A. brasilense (FBr+Az). Shoot dry weight, grain nitrogen content and grain yield were lower in 2018/19. In 2017/18, FBr+Az increased nodule number and dry weight compared with SBr. FBr+Az promoted a 47% increase in pods per plant compared with the control in both seasons. Regardless of season, grain nitrogen content was higher with FBr+Az (mean relative increase of 27%).

A strong correlation was obtained between red-edge based vegetation indexes and agronomic indicators (R2 > 0.40). Additionally, the all-subset regression method results demonstrated that the red-edge basis vegetation indexes were generally applied during different vegetation index combinations. The red-edge basis vegetation indexes reached an approximately 40% contribution in nitrogen nutrient index prediction and an approximately 48% contribution in leaf area index monitoring.

Iron deficiency reduced growth at non-saline treated plants by 27% while its deleterious effect was mitigated by the supply of 600 mM NaCl, mainly through the increase of photosynthetic pigment contents, iron accumulation in leaves, and intrinsic water use efficiency (iWUE), and the maintain of iron use efficiency (FeUE). Iron deficiency restricted iron accumulation in leaves (31%), iron absorption efficiency (FeAE) (38%), photosynthetic activity and pigment contents, and enhanced FeUE (48%) at saline treated plants. Otherwise, salinity enhanced growth (47%), root volume (20%), Fe accumulation in leaves (8%), and pigment contents at Fe-deficient plants. However, it reduced their FeAE (18%), transpiration rate (77%) and stomatal conductance (86%). Equally, it increased Na and Cl accumulation, the net photosynthetic assimilation rate and iWUE at Fe-deficient.

To enhance production, many growers use conventional fertilizers which also contribute to non-point source pollution. While there are a variety of methods used to administer fertilizers to crops, some require expensive equipment, are labor intensive, or apply fertilizers not efficiently used by plants. This study considered an alternative approach that delivered controlled-released fertilizers to tomatoes using gelatin capsules; wherein both seed and fertilizer were planted together as a single unit. The objectives were to determine if seed encapsulation altered seedling performance, while also considering the possible use of encapsulation to deliver controlled-release fertilizers. Although seed vigor tests suggest gelatin can diminish seedling performance, seed encapsulation had minimal impact on seedling emergence when planted in soils. Capsule treatments (without fertilizers) were taller than controls, and the addition of fertilizers improve plant performance, with higher fertilizer content fostering greater growth. The results suggest that seed encapsulation may be an effective way to deliver fertilizers to crop plants, and that the combination of capsules and controlled-release fertilizer could possibly lead to a reduction in the quantity of fertilizers necessary for tomato cultivation.","PeriodicalId":8154,"journal":{"name":"Archives of Agronomy and Soil Science","volume":"69 1","pages":"2862 - 2877"},"PeriodicalIF":2.4,"publicationDate":"2023-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47332634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
