Potassium fertilisation significantly enhances the lodging resistance index by promoting dry matter accumulation in soybean. However, the physiological mechanisms through which potassium affects the lodging resistance index remain unclear, particularly under different planting systems. In this study, we analysed the relationships between photosynthetic characteristics, root system, stem physiology, stem morphological characteristics, dry matter and lodging resistance index of soybean based on field experiments. The soybean cultivar Jinong 40 was used in both maize–soybean intercropping (maize: soybean as 6:6) and monoculture soybean systems (MS) in a two-year field experiment (2022–2023), with five potassium fertilisation levels (0 kg ha⁻¹, 30 kg ha⁻¹, 60 kg ha⁻¹, 90 kg ha⁻¹ and 120 kg ha⁻¹). Potassium application significantly improved chlorophyll fluorescence parameters, dry matter accumulation, stem lignin synthesis enzyme activity (phenylalanine ammonia-lyase, tyrosine ammonia-lyase and cinnamyl alcohol dehydrogenase), lodging resistance index and grain yield, regardless of the planting system. However, no significant differences in lodging resistance index or grain yield were observed between the potassium rates of 90 kg ha⁻¹ and 120 kg ha⁻¹. Compared to 0 kg ha⁻¹, increased potassium rates increased stem diameter by 17.8% and 15.5%, while the ratio of stem length to stem diameter ratio (L/D) decreased by 27.2% and 26.8% in maize–soybean intercropping and monoculture soybean systems, respectively. Across the high potassium inputs (90 kg ha⁻¹ and 120 kg ha⁻¹), phenylalanine ammonia-lyase (2.6%) and cinnamyl alcohol dehydrogenase (3.9%) were higher in the maize–soybean intercropping system compared to the monoculture soybean system. For the two planting patterns, the lodging resistance index was found to be more dependent on stem enzyme activity (93.5% for IS and 75.3% for MS) and L/D ratio (−81.0% for IS and −83.8% for MS), rather than stem length or root characteristics. We conclude that potassium application optimises stem diameter, enhances stem lignin synthesis and reduces the L/D ratio, therefore improving the soybean lodging resistance index and yield, especially in the maize–soybean intercropping system.</p>\u0000 </div>","PeriodicalId":14864,"journal":{"name":"Journal of Agronomy and Crop Science","volume":"211 2","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143447016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although research on oat tolerance to waterlogging is limited, there is evidence that oat may be a suitable alternative crop due to its resilience and ability to maintain yields despite nutrient imbalances caused by waterlogging. However, it remains uncertain how oat responds to changes in soil micronutrient availability during periods of waterlogging. Therefore, this study aims to investigate whether (1) micronutrient toxicities or deficiencies are induced during waterlogging, (2) the timing of the flooding event is relevant for the expression of a possible nutrient imbalance, and (3) micronutrient toxicities/deficiencies affect yield performance. In order not to exclude possible varietal differences, three oat varieties were grown in large-scale containers and exposed to 14 days of waterlogging at either BBCH 31 or BBCH 51. Although early but not late waterlogging was effective in reducing dry weights, especially in white oat, yield performance, as reflected by the harvest index, was not affected at all. While early waterlogging increased Mn and Fe concentrations in all oat varieties, they were well below toxic level. In contrast, Cu concentrations in white oat dropped below the deficiency threshold levels. Zinc status, however, remained completely unaffected in all oat varieties. After late waterlogging, only Mn accumulated to concentration in the toxicity range, but only in white and yellow oat; all other micronutrients remained in a sufficient range From these results we conclude, that although micronutrient imbalances occurred under waterlogging regardless from its timing, which may explain the transient reduction in dry weight of white oat, the yield of all tested oat varieties was ultimately unaffected. It can therefore be assumed that at least the oat varieties tested have a high regeneration potential and also show a high tolerance to transient micronutrient imbalances.</p>","PeriodicalId":14864,"journal":{"name":"Journal of Agronomy and Crop Science","volume":"211 2","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jac.70031","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 objective of this study was thus to examine two major carbon sources (i.e., photosynthetic assimilation in the flag leaf and remobilisation of pre-anthesis reserves in stems) and their interactions with sink strength in response to drought stress at different phenological stages. A greenhouse experiment was conducted at five water regimes: well-watered (WW), progressive drought (PD), and drought stress (DS) during vegetative growth (DS-V), early reproductive growth (DS-ER), and post-anthesis (DS-PA). Compared with the WW regime, the DS-V treatment reduced shoot biomass, grain yield, number of grains per pot, grain weight, harvest index, and water-soluble carbohydrates in stems despite the recovered photosynthesis after rehydration. Wheat plants subject to DS-PA exhibited reduced shoot biomass, grain yield, grain weight, and post-anthesis photosynthetic rate but greater depletion of water-soluble carbohydrates in stems during grain filling relative to the WW regime. Grain yield positively correlated with residual water-soluble carbohydrates in stems and late-season photosynthetic rates.

Identification and deployment of high-yielding and stress-tolerant maize hybrids adapted to stress-prone agro-ecologies is important for improving smallholding farmers' food security and livelihoods. The adaptation level among maize genotypes under heat and drought stresses is strongly affected by morphological and physiological aspects. The physiological traits, Normalised Difference Vegetative Index (NDVI), Soil Plant Analysis Development (SPAD) values, and morphological trait, leaf rolling, can be used as important secondary traits for the identification of the stress-tolerant genotypes, in addition to grain yield. In this view, the present study was conducted at the Agricultural Research Station, Bheemarayangudi, and the Main Agricultural Research Station, Raichur, under heat stress (Summer-2020 &amp; 2021) and drought (<i>Rabi</i>-2021-22) conditions.

Understanding how water stress impacts crop yield is crucial for developing effective irrigation strategies in drought-inclined areas. This study investigates the relationship between silage soybean forage yield and water stress indices, specifically the Crop Water Stress Index (CWSI) and the Water Deficit Index (WDI). In addition, water-yield relations were also determined. The study was carried out in a randomised complete block design with four irrigation levels (S100, S75, S50, S25), three replications, and a period of 2 years. At the end of the study, crop evapotranspiration (ET), irrigation (I), water use efficiency (WUE) and forage yield decreased as irrigation water levels were reduced from S100 to S25. ET was found to be between 501 and 755 mm, WUE was found to be between 2.61 and 3.58 kg m⁻³, irrigation water use efficiency was found to be between 2.53 and 2.97 kg m⁻³, forage yield was found to be between 15.4 and 26.2 t ha⁻¹, WDI varied between 0.16 and 0.5, and CWSI ranged between 0.34 and 0.90. The results revealed that silage soybean should be irrigated when the average CWSI value is nearly 0.36 and the average WDI value is nearly 0.26 for high yield. The rate of decrease in forage yield from S100 to S25 was compared with the rate of increase in WDI and CWSI. In the first year of the study, there was a 45% decrease in forage yield between S100 and S25, while CWSI increased by 65%. However, this situation was 40% in WDI. In the second year of the study, there was a 38% decrease in forage yield from S100 to S25, while CWSI increased by 33% and WDI increased by 26%. The relationship between forage yield and stress indices is inversely proportional. The fact that the values in CWSI were proportionally higher than WDI suggested that the calculations were made without taking into account the soil temperatures during the measurement. Water stress indices were correlated with forage yield and regression analysis was performed. Although relations of forage yield and water stress indices showed slightly higher correlations with WDI, this could not strongly suggest that WDI was more accurate than CWSI.
