Abstract The use of saline water under drought conditions is critical for sustainable agricultural development in arid regions. Biochar used as a soil amendment to enhance properties such water-holding capacity and the source nutrition elements plants. Thus, research was carried out assess impact biochar treatment on morphological physiological characteristics production Solanum lycopersicum greenhouses exposed stresses. study structured three-factorial split-split-plot design. There were 16 treatments across three variables: (i) quality, with freshwater water, electrical conductivities 0.9 2.4 dS m − 1 , respectively; (ii) irrigation level, 40%, 60%, 80%, 100% total evapotranspiration (ETC); (iii) application, addition at 3% dosage by (w/w) (BC ), control 0% ). findings demonstrated that salt deficiency hurt physiological, morphological, yield characteristics. Conversely, enhanced all Growth-related parameters, plant height, stem diameter, leaf area, dry wet weight, gas exchange attributes, rate transpiration photosynthesis, conductivity, well relative content decreased stresses, especially when 60% ETc or 40% ETc. resulted substantial enhancement vegetative growth-related characteristics, efficiency use, yield, reduced proline levels. Tomato 4%, 16%, 8%, different levels deficit (100% ETc, 80% ETc) than Overall, (3%) combined shows potential morpho-physiological support tomato plants, improve higher WUE semi-arid areas.

Optimal irrigation-fertilization-aeration subsequently enhance greenhouse tomato yields and fruit quality. In addition, the optimization of these agricultural practices is essential to improve irrigation water productivity (WPI). this context, present study aims assess effects combined irrigation, fertilization, aeration treatments on yield (Y), evapotranspiration (ET), WPI, To achieve objective, we applied two cumulative pan evaporation (Epan) -based (I1: 1.0 Epan; I2: 0.8 Epan), three nitrogen fertilization (F1: 120 kg/ha; F2: 180 F3: 240 kg/ha), venturi injector-based rates (A1: single Venturi aeration; A2: double CK: unaerated) in triplicates. total, 15 treatment scenarios were considered study, including a control group (CKI1). Each was replicated times. According obtained results, harvesting time cultivated strongly affected by levels due differences soil oxygen contents. The A2 demonstrated stronger promoting effect early ripening than those under A1 CK scenarios. Indeed, first harvest amount higher 32.24% 36.45% (P < 0.05), respectively. there significant increases (WPC) WPI values with decreasing rates. contrast, ET Y substantially decreased. Specifically, I1 scenario 11.38% 8.65% observed I2 scenario, On other hand, WPC 12.01% 13.09% lower treatment, results showed also irrigation-aeration, irrigation-fertilization, aeration-fertilization interaction ET, Y, WPC, 0.01). considerably influenced sugar-acid ratio organic acid, soluble sugar, lycopene contents tomatoes. fact, an important indicator quality, showing positive correlation comprehensive quality scores.

Vapour pressure deficit affects crop water productivity, yield, and quality in tomatoes

Agricultural Water Management, Год журнала: 2024, Номер 299, С. 108879 - 108879

A high atmospheric vapour pressure deficit (VPD) hinders calcium absorption in tomatoes (Solanum lycopersicum L.), which severely reduces tomato yield, crop water productivity (WPcrop), and quality. Although reducing the VPD is effective for increasing yield productivity, regulating costly. Therefore, this study aimed to explore effects of regulation (high VPD=2.22 kPa, low VPD=0.95 kPa) during different growth stages on WPcrop, quality identify a management method that saves costs enhances above parameters. The results showed was significantly positively correlated with fruit absorption. Decreasing expansion stage it flowering increased accumulation fruits, thereby improving Additionally, stomatal conductance mesophyll conductance, intercellular chloroplast CO2 concentrations enhancing plant photosynthetic capacity, reduced stem potential, leaf relative content, potential difference, hydraulic By integrating game theory technique order preference by similarity ideal solution method, comprehensive analysis appearance, nutrients, flavour revealed growing plants under seedling, flowering, ripening not only enhanced value but also maximally humidification cost. Conclusively, controlling environmental at 2.22 kPa 0.95 can effectively increase This provides theoretical basis high-quality, efficient, water-conserving cultivation greenhouse tomatoes.

The promise of resurrection plants in enhancing crop tolerance to water scarcity

Philosophical Transactions of the Royal Society B Biological Sciences, Год журнала: 2025, Номер 380(1927)

Опубликована: Май 29, 2025

Climate change affects the agricultural sector by modifying precipitation patterns, increasing extreme weather events, and geographically shifting agriculturally viable areas. These climate alterations substantially impact plant resilience to abiotic stress and, consequently, productivity. A better understanding of adaptations tolerate environmental conditions could pave way for future advances in sustainability. One such adaptation is vegetative desiccation tolerance (VDT), which enables some species, known as ‘resurrection plants’, undergo almost complete drying without losing viability. The current review discusses how incorporating different molecular biochemical mechanisms underlying VDT into crops might expand time during can continue growing under limiting water perhaps broaden range survivable negative potentials that a crop endure drought stress. Such possibilities alleviate detrimental consequences low availability crops. Understanding plants survive dehydration has potential enlighten new strategies improve resiliency crops, thereby positively impacting worldwide food security This article part theme issue ‘Crops stress: we mitigate impacts on agriculture launch ‘Resilience Revolution’?’.
