“…In this experiment, compared with the output in CK, mild (WD3) and moderate (WD7) regulated de cits in the tuber enlargement stage signi cantly decreased the output by 20.86% and 26.50%, respectively. Consistent with this study, Mustafa Ünlü et al 38 , Hassan et al 39 , Nagaz et al 40 , and Im et al 41 also found that water de cit at the tuber enlargement stage reduces production by approximately 20% compared with that with a su cient water supply. As tubers begin to divide and expand in the tuber enlargement stage, potatoes transition from the reproductive stage to the vegetative growth stage.…”

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.

“…However, when the SSI irrigation technique was combined with BPE soil mulch under the DI regime, it was found to be the most effective in conserving irrigation water. This combination not only mitigated the negative effects of the DI regime but also promoted plant health and improved water productivity (Abdelhady et al, 2017;Chen et al, 2018;Abd El-Wahed et al, 2020;Sang et al, 2020).…”

“…Mulching soil with either organic materials or black polyethylene sheets, even though the black polyethylene sheets are more effective than organic materials, reduces evaporation, retains soil moisture, decreases the effect of ambient temperature on soil temperature, and suppresses weed growth. These all can support better vegetative growth and overall plant health (Abdelhady et al, 2017;Chen et al, 2018;Abd El-Wahed et al, 2020;Sang et al, 2020).…”

Irrigated agriculture from now on should be implemented under water scarcity. Hence, this research was designed to determine the optimal interaction between irrigation water-rationing strategy (deficit irrigation), irrigation techniques, and soil mulching to improve water use efficiency and maintaining plant performance as well as yield productivity of tomatoes. The experiment was set up during the 2020-2021 and 2021-2022 growing seasons. Three factors were studied: two drip irrigation techniques, surface (SI) and subsurface (SSI) irrigation, and two irrigation rates, 100% ETc for full irrigation (FI) and 60% ETc for deficit-irrigation (DI) along with three treatments of soil mulching, bare soil (BS), organic mulch (OrM) and black polyethylene mulch (BPE). The results demonstrated that applying the absolute regular DI regime significantly reduced vegetative growth, fruit yield, and yield component along with water productivity. Also, it reduced the physiological function measures, and nutrient content of the tomato leaf. Meanwhile, applying the DI regime via the SSI technique and integrated with BPE soil mulching proved the best optimization of the DI negative effect followed by applying the DI regime through either SSI or SI technique combined with OrM or BPE soil mulching, respectively. As a result, it is advisable to use the integration of DI via the SSI accompanied by BPE soil mulching since this is considered a good method for conserving irrigation water from being lost by both evaporation and seepage out of the root zone improving water use efficiency without significantly reducing tomato yield.

“…The high light transmission increased soil temperature and created a microclimate conducive to weed germination (Rajablariani et al, 2015). Tomato (Solanum lycopersicum), a solanaceous crop, is the most important horticultural crop in the world (Schwarz et al, 2014;Bhandari et al, 2017), and ranks first among all vegetable crops farmed in Egypt (El-Wahed et al, 2020). It is well adapted to its soil and climate conditions and grown all year round (Shamshiri et al, 2018).…”

To manage natural resources and achieve agricultural sustainability, effective production strategies are required. For a healthier crop and a cleaner environment, reducing or eliminating chemical use is also a desirable goal. The goal of this study was to see how soil polyethylene mulch affected tomato crop output and quality. The Experimental Farm of the Faculty of Agriculture, Sohag University, Egypt, was used for two consecutive early summer seasons production. Manual weeding was used as a positive control treatment to compare its effect with black plastic mulch and herbicide on the growth, yield, and quality of two tomato hybrids (G.S-12 and Fayrouz). Weed density and biomass and economic profitability levels were also investigated. The use of black plastic mulch greatly enhanced all of the measured characteristics in both seasons, according to the data. i.e., vegetative traits, vitamin C content, total soluble solids, and N, P, and K leaves' concentrations. Data also revealed a superiority of G.S-12 hybrid over Fayrouz hybrid in most characters. Results showed a surprising effect for black plastic mulch treatment on smothering weed emergence compared with the conventional manual or chemical weed control treatments during the two seasons of considering. The hand-hoeing treatment proved to be the least viable weed control system among all treatments. This study recommends applying black plastic soil mulch in tomato production particularly in reclaimed soil conditions to reduce labor requirements and produce a higher, healthier output. In terms of gross margin and benefit-cost ratio (BCR) analyses, it also showed to be the optimum strategy.
