“…Nemeskéri et al [14], Chen et al [33], Patanè et al [68], Pék et al [69], Helyes et al [70], also reported that the best marketable yields of tomato are always reached with the highest water supply rate. The highest marketable yields recorded in this study were under the 70-100% FC water stress treatment (full irrigation) with a value of 170 t/ha and 135 t/ha for sandy loam and silty loam soils, respectively, which is no different from the findings of Takács et al [71] and Lu et al [72], who suggest that the rate of regulated deficit irrigation should be no less than 50% of water demand because, under this level, the water stress is too severe. However, water stress treatment had a strong correlation with crop yield (R 2 = 0.9758 and 0.9816 p < 0.01) for sandy loam and silty loam soils, respectively, and also had a strong correlation with Ec (R 2 = 0.9651, p < 0.01).…”

Drought and water scarcity due to global warming, climate change, and social development have been the most death-defying threat to global agriculture production for the optimization of water and food security. Reflectance indices obtained by an Analytical Spectral Device (ASD) Spec 4 hyperspectral spectrometer from tomato growth in two soil texture types exposed to four water stress levels (70–100% FC, 60–70% FC, 50–60% FC, and 40–50% FC) was deployed to schedule irrigation and management of crops’ water stress. The treatments were replicated four times in a randomized complete block design (RCBD) in a 2 × 4 factorial experiment. Water stress treatments were monitored with Time Domain Reflectometer (TDR) every 12 h before and after irrigation to maintain soil water content at the desired (FC%). Soil electrical conductivity (Ec) was measured daily throughout the growth cycle of tomatoes in both soil types. Ec was revealing a strong correlation with water stress at R2 above 0.95 p < 0.001. Yield was measured at the end of the end of the growing season. The results revealed that yield had a high correlation with water stress at R2 = 0.9758 and 0.9816 p < 0.01 for sandy loam and silty loam soils, respectively. Leaf temperature (LT °C), relative leaf water content (RLWC), leaf chlorophyll content (LCC), Leaf area index (LAI), were measured at each growth stage at the same time spectral reflectance data were measured throughout the growth period. Spectral reflectance indices used were grouped into three: (1) greenness vegetative indices; (2) water overtone vegetation indices; (3) Photochemical Reflectance Index centered at 570 nm (PRI570), and normalized PRI (PRInorm). These reflectance indices were strongly correlated with all four water stress indicators and yield. The results revealed that NDVI, RDVI, WI, NDWI, NDWI1640, PRI570, and PRInorm were the most sensitive indices for estimating crop water stress at each growth stage in both sandy loam and silty loam soils at R2 above 0.35. This study recounts the depth of 858 to 1640 nm band absorption to water stress estimation, comparing it to other band depths to give an insight into the usefulness of ground-based hyperspectral reflectance indices for assessing crop water stress at different growth stages in different soil types.

The effects of the amount and timing of regulated deficit drip irrigation under plastic film on potato (‘Qingshu 168’) growth, photosynthesis, yield, water use efficiency, and quality were examined from 2017 to 2019 in cold and arid northwestern China. A two-factor randomized design was used with two levels of regulated deficit irrigation (mild, moderate) applied in four stages of potato growth (seedling, tuber initiation, tuber bulking, starch accumulation). Growth and photosynthetic parameters were determined in each growth stage, and yield and quality were measured after harvest. The net photosynthetic rate, stomatal conductance, and transpiration rate decreased significantly under water deficit in the tuber formation and starch accumulation stages, and the decreases were greater with moderate than mild water deficit. Although water deficit reduced potato yields, potato subjected to mild water deficit in the seedling stage had the highest yield at 43,961.91 kg·ha−1, followed by those subjected to mild water deficit in the starch accumulation stage at 42,262.25 kg·ha−1, which were decreases of only 4.50% and 8.19%, respectively, compared with potato under full irrigation. The highest water use efficiency was in potatoes subjected to mild water deficit in the seedling stage (8.67 kg·m−3), with the second highest in those subjected to moderate water deficit in the seedling stage (8.28 kg·m−3), which were significant improvements by 10.87% and 5.84%, respectively, compared with full irrigation. The highest overall quality was in potatoes subjected to mild and moderate water deficit in the seedling stage. The starch content in potatoes with mild water deficit in the seedling stage increased by 3.34% compared with that under full irrigation. In addition, the protein and vitamin C contents in potatoes under moderate water deficit increased significantly by 0.77% and 21.59%, respectively, compared with the contents under full irrigation. Principal component analysis identified mild water stress in the seedling stage as the optimum regulated deficit irrigation regime for potato. Thus, the relative soil water content should be maintained at 55% to 65% of field capacity in the seedling stage but at 65% to 75% in the other growth stages. The results of this study provide theoretical and technical references for efficient water-saving cultivation and industrialization of potato in cold and arid northwestern China.

“…Tomato is a highly water consuming crop (Cantero-Navarro et al, 2016). Because of the water shortage, this crop may be cultivated under deficit irrigation (Lu et al, 2019) and this may affect the outcome yield quantity and quality (Giuliani et al, 2018). Water use efficiency can be expressed in terms of amount of yield production (kg) per unit consumption of irrigation water (m 3 ) (Jerry and Christian, 2019).…”

W ATER scarcity is a global issue especially in arid regions and rationalizing the use of fresh irrigation water has become necessary to satisfy water needs. The current study investigates using Si to alleviate the implications of water stress on tomato plants grown on a light textured soil. A split-plot experiment was conducted under the field conditions for two successive seasons (2017 and 2018) on tomato under two deficit irrigation levels i.e. 70 and 85% ET c as well as 100% ETc for comparison. Plants were subjected to two levels of silica foliar spray (0 and 0.4 mM). At physiological maturity growth stage, chemical characteristics of tomato fruits as well as total fruit yield were determined. Deficit irrigation decreased contents of chlorophyll A and B in leaves; while increased proline content in plant roots. This consequently decreased tomato fruit yield; while, raised its contents of total dissolved solids and vitamin C. On the other hand, spraying plants with Si raised significantly chlorophyll A and B in leaves and alleviated plant stress by increasing proline content in roots. This increased significantly fruit yield. Irrigation with 85% Et c with Si spray recorded a rather similar fruit yield to those irrigated with 100% Et c. Moreover, Si treatments increased significantly water use efficiency by the crop. Thus, Si spray can take part in saving considered amounts of water that can be used for irrigation of further tomato areas.
