“…The supply of water for olive groves is one of the most important factors in the development of olive cultivation. Considering the serious risk of drought and water shortages, especially during the last few years, it is necessary to adopt appropriate methods for optimum utilization of water resources, including using resistant cultivars (35), determining critical irrigation times (36), using mulch (37), and using plant growth regulators (32). The water is an important limiting factor for agricultural producers in arid and semi-arid regions in the world (38).…”

Water stress is one of the important abiotic environmental stresses that threaten the agricultural -products in the world. This experiment was carried out to determine the effect of water stress on physiological and biochemical characteristics of three commercial olive cultivars. A factorial pot experiment was conducted in the field conditions using completely randomized design in Gilan-Gharb city, Kermanshah province during 2015. One-year-old rooted cuttings of Zard, Amigdalolia and Konservolia olive cultivars were planted in 12-liter pots and subjected to three irrigation treatments. Irrigation treatments included control (100% of field capacity), 75% and 50% field capacity. Physiological and biochemical characteristics such as relative water content (RWC), electrolyte leakage (EL), calcium, potassium and sodium content, total phenol, malondialdehyde, peroxidases, catalase, a, b and total chlorophyll, proline and total carbohydrate were measured. Results showed that relative water content, K & Ca was reduced while sodium content increased by increasing water stress. Chlorophyll content was higher in Konservolia cultivar under water stress in comparison to the others. Water stress induced increasing in proline, total phenol and soluble carbohydrate in all cultivars. The highest total phenol and proline was recorded in Zard cultivar under water stress. Total carbohydrate increased significantly (P<0.05) in Konservolia in comparison to the others. Malondialdehyde content was increased as an index of oxidative stress by drought. The highest peroxidases and catalase activity were recorded under drought stress of 50% irrigation in Konservolia olive cultivar. Generally based on results Konservolia, Zard and Amigdalolia were more tolerant respectively.

“…The decrease in total polyphenol content in Konservolia Olive trees due to polyethylene mulching foil treatment compared with the mulch-free condition was reported by Gholami et al (2020) [26]. After the application of the mulch film, there was a decrease in the average value of total polyphenol content or total antioxidant capacity also in Japanese plum grown under polyethylene film, as documented by Melgarejo et al (2012) [10].…”

The influence of the cultivation method on green pepper fruits was investigated. Six pepper cultivars were planted using soil covered by brown mulching foil and in uncovered soil. Cultivation was maintained for two years providing the equivalent conditions of cultivation. The ascorbic acid content, total antioxidant capacity, total polyphenol content, soluble solids content and yield were observed and compared to mulching foil application, year of cultivation, pepper variety and order of harvest. The obtained results proved a statistically significant effect of mulching film in all tested varieties; the effects of year of cultivation and plant variety were also confirmed. The mulching film had a positive effect on pepper yield. The highest yield of peppers was grown on mulching foil in the variety ‘Lungy’. The vitamin C content, total antioxidant capacity, total phenolic content and soluble solids content were demonstrably higher in the variant without mulching film. The highest levels of total polyphenol content and total antioxidant capacity were determined in the ‘Yolo wonder’ variety, the darkest colored cultivar. The highest content of vitamin C and soluble solids content were found in the ‘Semaroh’ variety grown without mulching film, however, this variety achieved the lowest yield growing with mulching foil.

“…The application of the PM at depth of 120 cm in the soil resulted in increasing the root length under CWR of 100 and 70%, however, the application of both mulches has reduced the root length. Drought stress has reduced the length, fresh and dry weights of different plants such as olives (Gholami and Zahedi, 2020), strawberries Egypt. J. Hort.…”

E GGPLANT (Solanum melongena L.) is one of the drought-tolerant vegetable crops, however, recently climate change has had a devastating impact on crop cultivation in many parts of Iran. The present research aimed to investigate the application of date straw mulches (DSM) and plastic mulches (PM) on yield and morphological and physiological characters of the plant under different crop water requirements. A split-split plot experiment using an RCB design with three replications in Rodan, Hormozgan, Iran at 2017. The three levels of crop water requirement (CWR), i.e. 40, 70, and 100%, the two levels of DSM (i.e. control and DSM), and the three levels of PM (i.e. 0, 100, and 120 cm in soil depths), were allocated in the main, sub and sub-sub plots, respectively. The results of the analysis of variance revealed that the triple-interaction effects of the DSM, PM, and CWR were statically significant for all traits (P < 0.05 or P < 0.01). However, none of the simple and interactions effects were not statically significant for leaf length and width. The results revealed that 40% of CWR reduced the yield by 49% compared with 100% CWR. Also, the application of the DSM and PM alleviated the deleterious effects of water deficit. Finally, the application of the mulches is recommended for eggplant in areas affected by water shortages.
