Unreasonable irrigation and nitrogen application reduce tomato yield waste resources. This study explored the effects of water conservation reduction on yield, dry matter, quality, productivity use efficiency in Northeast China. Experiments were conducted during 2020 2021 at three levels (85–95 %, 75–85 65–75 % θFC) (120, 180, 240 kg hm−2). The optimal supply patterns obtained by establishing a newly evaluated Entropy Weight Method−Technique for Order Preference Similarity to Ideal Solution−Adversarial Interpretive Structure Model (EWM−TOPSIS−AISM). results showed that amount significantly affected quality (P ≤ 0.5). Proper deficit improved quality. Reducing rate but decreased yield. Increasing increased efficiency.

In an arid region, water shortage limits agricultural development, and worse, soil salinization is accompanied by moisture drought. this hydraulic lift occurs due to the drying upper layer caused high precipitation wet lower layer. Hydraulic defined as redistribution from wetter, deeper layers drier, shallower near surface through plant roots. To examine effects of salt stresses on tomato yield fruit quality under condition lift, a 2year experiment was conducted. Different treatments were designed, including three levels (W1, W2 W3 indicating contents 60%–70%, 50%–60% 40%–50% field capacity, respectively) four (S0, S1, S2 S3 NaCl addition 0%, 0.2%, 0.4% 0.6% dry weight, pot, control treatment (CK) W1 S0, respectively.

The olive tree (Olea europaea L.) is the main fruit in most of arid and semi-arid regions Tunisia, which where problem salinity more pronounced. Salinity one factors that affects productivity trees, so objective this experiment was to study effects on photosynthesis, water relations, mineral status, enzymatic activity two cultivars Olea L., 'Chemlali' 'Koroneiki'. trial conducted under controlled conditions a greenhouse for period 49 days included treatments: T0 control T100 (irrigation with 100 mM NaCl solution). Under stress, stomatal conductance, leaves both were negatively affected. showed greater tolerance salinity, based progressive decrease osmotic potential (Ψπ) followed by synchronous gs, without comparable photosynthesis. use efficiency (WUE) improved as result. In addition, K+/Na+ ratio rose. This appears be crucial managing stress. Conversely, an accumulation glutathione peroxidase (GPX) stressed plants. catalase (CAT) ascorbate (APX) content decreased varieties. It can concluded cultivar 'Koroneiki' susceptible salt stress than 'Chemlali', because GPX decreases CAT APX pronounced cultivar.

Abstract The enhancement of saline soil yield potential by biochar was well-documented, but the changes brought particle size on properties and crop performance are not well understood. To investigate in tomato due to under varying salt stress, we conducted a pot experiment China Northwest’s solar greenhouse. A total nine treatments were applied, with three different amounts [S0 (no salt), S1 (0.3% dry weight), S2 (0.6% weight)], B0, B1, B2 (0, 0.5% large particles small particles). Adding did significantly affect measured chemical properties, except for pH, nitrogen (TN), Ca 2+ . Specifically, addition increased pH TN, while reduced 2 ⁺ content likely selective adsorption ⁺. Biochar had opposite effects stress levels. Compared S0, B1 19.1% 36.5% higher, whereas B2, 33.1% 44.2% lower S2, respectively. Under no small-size 51.0% compared largely improved water nutrient status. These results great value developing better strategies adding appropriate into soils achieve greater productivity gains. Highlights 16.7–37.9%, there significant difference other cations. Large-size alleviated promoting leaching enhancing nutrients. Small exacerbated salinity higher treatments. boosted without stress.

Excessive irrigation wastes resources and impairs plant dry matter yield. The study explored the effects of three levels (I1: 65–85% θ_f, I2: 60–80% I3: 55–75% θ_f) a fully irrigated control (CK: 70–90% on grape matter, yield, resource use efficiency in solar greenhouse from 2023 to 2024. Results showed that treatments significantly affected accumulation organs aboveground parts, especially during fruit swelling maturity stages. logistic model simulated accumulation, with maximum theoretical (A) being most sensitive water changes. I3 treatment reduced A by 12.4-43.04% stem, 3.80-15.09% leaf, 3.87–26.45% fruit, 8.23–35.27% parts. Lower amount shortened rapid growth stage duration (T₂) decreased rate time (X_max) (V_max) average (V_avg) rates. At maturity, lower promoted allocation leaves fruits but Mantel test revealed seven characteristic parameters were positively correlated yield radiation (RUE) (p < 0.05, r ≥ 0.2). random forest identified y₃ y₁ (the gradually slow stages) as critical influencing RUE.

Agronomy, Journal Year: 2025, Volume and Issue: 15(5), P. 1068 - 1068

Published: April 28, 2025

The inefficient irrigation strategy is an important factor affecting the yield and water productivity of tomatoes in greenhouses, seriously hindering development cultivation industry. While impact level on tomato growth has been extensively studied, interval, another crucial component schedule, as well their interaction, remain poorly explored. There were four levels (W1: 125% ETc, W2: 100% W3: 75% W4: 50% ETc; ETc represented crop evapotranspiration) three intervals (D1: 4-day D2: 7-day D3: 10-day interval), aiming to explore effects different performance tomatoes. Here, we showed that moderate increases interval promoted root growth, improved nitrogen uptake distribution, enhanced plant height, stem diameter, leaf area index, aboveground biomass, thereby promoting net photosynthetic rate plants fruit yield. quality indicators total soluble solids, vitamin C, sugar decreased with increasing but increased decreasing interval. Higher consumption resulted lower water-nitrogen use efficiency. Overall, compared W2D2 W2D3, W2D1 by 8.0% 26.1%, respectively, 5.7% 19.3%, 7.1% 17.5%, respectively. In addition, organs then increase level, while it consistently At harvest period, followed order > stem.
