Abstract The increasing evaporative demand due to climate change will significantly affect the balance of carbon assimilation and water losses plants worldwide. development crop varieties with improved water-use efficiency (WUE) be critical for adapting agricultural strategies under predicted future climates. This review aims summarize most important leaf morpho-physiological constraints WUE in C3 identify gaps knowledge. From gain side WUE, discussed parameters are mesophyll conductance, carboxylation respiratory losses. traits affecting waterside this stomatal size density, control residual (cuticular bark conductance), nocturnal conductance hydraulic conductance. In addition, we impact anatomy crown architecture on both loss components WUE. There multiple possible targets understanding sources variability plants. We identified as greatest knowledge whole-plant assessments. Moreover, trichomes, canopy structure plants’ is still not well understood. a multi-trait approach urgently needed better dynamics optimization.

Agricultural Water Management, Год журнала: 2023, Номер 289, С. 108523 - 108523

Опубликована: Сен. 22, 2023

This review emphasizes the significance of combining regulated deficit irrigation (RDI) with woody crops, as they have higher water productivity (WP) and are tolerant to mild deficits. After conducting analysis, it was found that for most reducing by 20.0–30.0% has a negligible impact on yield, typically within variation range 10.0%, leads an increase in WP 10.0–30.0%. When is reduced 40.0–50.0%, yield varies significantly depending species, but generally approaches its highest value; general, can 25.0% or more sometimes even exceed 50.0%. However, when further reduced, affects there limited decrease WP. Moreover, adjusting amounts during noncritical demand periods minimizes fruit size, enhancing water-saving effectiveness. Water-saving techniques trigger various plant responses, improving resistance deficits, promoting reproductive growth, protecting against drought-related damage. Despite potential reductions, ongoing research demonstrates positive outcomes WP, crop quality crops. offer economic benefits through cost savings pest reduction, while finding appropriate balance between use, vital agricultural success sustainable resource management. optimize nutrient uptake heavy metal absorption systems, addressing stress, soil salinization, emissions. Combining multiple methods, such partial root-zone drying (PRD), shows immense conservation fruits. Integrating PRD innovative techniques, precision sensor-based promises remarkable optimized yields, revolutionizing practices scarcity challenges

Farmland mulching and optimized irrigation increase water productivity and seed yield by regulating functional parameters of soybean (Glycine max L.) leaves

Agricultural Water Management, Год журнала: 2024, Номер 298, С. 108875 - 108875

In both arid and semi-arid regions, adopting field mulching can effectively optimize soil moisture distribution, enhance crop yields, improve water productivity. While acknowledging its advantages, seems insufficient for maintaining high productivity due to the increasing frequency of extreme weather. Furthermore, drought often coincides with critical growth stages, necessitating implementation agricultural irrigation ensure normal growth. Accordingly, we conducted a three-year experiment from 2021 2023 including three typical methods (no mulching, NM; straw SM; plastic film FM) supplementary strategies (irrigated at branching stage (V4), W1; irrigated pod-filling (R2), W2; V4 R2 stage, W3). Throughout entire period, monitored conditions each treatment, measured leaf physiological parameters crucial assessed soybean yields (WP). Our findings indicated that, relative SM NM, FM maintains optimal balance, augments chlorophyll content, enhances photosynthesis, resulting in an average yield increase 17.0% 38.3% over growing seasons. Additionally, also significantly affects seed soybean. FMW2 achieved higher (4307.5 kg ha−1, 3-year averaged), had insignificant difference highest 4568.6 than other treatments. Similarly, area index, net photosynthetic rate (Pn) transpiration (Tr) presented between FMW3, while WUEleaf (Pn/Tr) obviously that FMW3. As result, WP 12.2 ha−1 mm−1 seasons, compared treatments, ranges 5.6% 46.7%. summary, treatment optimized distribution meet demands soybeans during reproductive achieving beneficial balance production by regulating functional parameters. Future research will explore more specific scheduling techniques (e.g., precision irrigation, deficit sensor-based management systems) integrating innovative materials biodegradable films) further resilience under evolving climatic conditions.

Manure application is considered a good way to modify soil structure and hydraulic properties has the potential promote water productivity. Therefore, for improving savings productivity through use of manure as substitute mineral fertilizer worth further exploration in deficit irrigation regions. A field experiment with four regimes types inputs was conducted North China Plain. The included W0 (no irrigation), W1 (irrigation at presowing stage only), W2 jointing stages), W3 presowing, jointing, anthesis stages). CK fertilizer), M0 (mineral M50 (half plus half manure), M100 (manure only). Sixteen treatments were laid out 2012, samples collected 2018–2019 2019–2020 during winter wheat growing season. results showed that greatest improve obtain greater grain yield occurred than while interacting precipitation; both these yields significantly those other treatments. leaf area index (LAI) plays an important role regulating consumption negatively correlated evaporation accumulation ratio evapotranspiration. However, compared under pure application, LAI alone could not ensure equal LAI, lower by 7.66% 13.62%, respectively, two years.

Reduced irrigation and high soil salinity are widely recognized to decrease tomato yield, but they can improve fruit quality water use efficiency (WUE) when imposed appropriately. However, the response of plant their interaction is still unclear, quantitative relationship WUE with under different regimes also lacking. This study investigated responses tomatoes in terms quality, based on yield (WUEy), biomass (WUEb), leaf (iWUE) twelve treatments, consisting combinations three relative field capacity (FC) (W0, W1, W2 refer 95 % FC, 75 60 respectively) four levels (0 g, 2 4 6 g salt mixtures added 1000 air-dried soil, respectively). Results showed that WUEy WUEb had a negative correlation regimes. Salinity resulted greater reduction than consumption compared control treatment. Therefore, lower plants treatment alleviated induced by certain extent. From scale, iWUE was positively linearly related salinity, indicating stomatal regulation more prone reduced conductance net photosynthetic rate W0 W1. Whilst it quadratic W2, results supported highly salinity-induced dependent supply. In addition, although fresh mass (FM), dry matter content, content (WC) titratable acidity (TA) total soluble solids (TSS) were proportional regardless The W1 increased sensitivity TA TSS weak FM WC salinity. Thus, we deduced mildly an appropriate strategy regulate conditions. provides regime management basis for comprehensive changes WUE, grown saline soils.

Biochar is a soil amendment that can change soil's physical and hydraulic properties. However, biochar application far from being 'one size fits-all' approach. The impact of the management practices dependent on type (feedstock production conditions), depth method, climate site characteristics. Hence, this study aims to enrich available inconclusive information how could affect clay loamy assess potential induced water stress mitigation rain-fed durum wheat under specific condition semi-arid environment North West Tunisia. A field experiment was investigated in which three rates 0 (B0), 10 (equivalent 0.5% weight) (B1) 20 t/ha 1% weight), (B2), were tested. Other laboratory analysis allowed evaluation retention curve (SWRC), saturated conductivity (Ks), dry density (ρb) biostress biomarkers such as glutathione-S-transferase (GST), catalase activities (CAT) malondialdehyde content (MDA) well yield attributes. Results showed treatment B2 significantly decreased ρb Ks with relative values about -3.1% -19%. Consequently, SWRC better capacity, mostly saturation matric value (h) 33 kPa.
