Abstract As water assets become scant, it is hard to inundate yields to satisfy their full need. Egypt district is viewed as one of the weakest locales to environmental change impacts, because of its water shortage, which is the most elevated in the Bedouin world. Upgrades to water system the board is proposed as a method of expanding horticultural creation and diminishing the interest in water. One approach to accomplish more noteworthy water use productivity in the water systems is changing from the less proficient flood or wrinkle framework to more effective frameworks, for example, dribble water system (surface, subsurface) or to embrace water system techniques, like deficiency water system, to augment crop yield and additionally limit water misfortunes. The specific destinations of this review : 1-To decide the impact of various water system levels and two sorts of water systems (surface and sub-surface) on cucumber and zucchini yields . 2-To decide the ideal water use and water efficiency for the two vegetables crop. 3-To establish optimal water management strategies for vegetables crops for the purpose of achieving more WP in limited water or water stressed environments. 4-Comparison surface and sub-surface drip irrigation under different irrigation level, and their interaction. 5-Comparision 2 l/h and 4 l/h flow rate dripper under different irrigation level. The examination was completed under greenhouse conditions on a silty clay soil at the Experimental station, greenhouse of Agriculture Research Centre, Dokii, Giza Governorate, in season 2018/2019 and 2019/2020 to concentrate on the impact of irrigation levels, using surface 49 SUMMARY AND CONCLUSIONS Esraa M. Masria, (2022), M.Sc., Fac. Agric., Ain Shams Univ. and subsurface drip irrigation on yield of cucumber and zucchini by using different emitters 2 l./h and 4 l/h, the irrigation water use efficiency, growth parameters and total production. Irrigation water has been acquired from well (situated in the trial region), with pH 7.3 and a normal electrical conductivity of 500 ppm. The cultivar of cucumber (Cucumis sativus L.) and zucchini (Cucurbitaceace) was used for this experiment. Seedlings were transplanted at four-leaf stage (after 35 days from seed sowing) in May 2018 as a first cycle and January 2019 second cycle for cucumber. On September 2018 as a first cycle and July 2019 as a second cycle for zucchini crop the experiment was consisted of three irrigation water levels (T1: 100% ETc, T2: 80% ETc and T3: 50% ETc) accompanied with two types of drip irrigation systems (S: surface and SS: subsurface) and two types of flow rate dripper (2 l/h and 4 l/h). Irrigation was applied during the whole growing season. The results of this study are summarized as follows: 1. Subsurface dribble water system (SSDI) had higher worth of soil dampness content. This is expected to decrease vanishing from soil surface by setting streamline under soil surface. The dirt dampness content under full water system T1 (100% ETC) was higher than under shortage medicines for both irrigation system. 3. A full water applied (100% ETC) is needed to amplify yield in cucumber and zucchini developed in parched environment conditions , 4. The cucumber and zucchini yield were higher utilizing subsurface dribble water system contrasted with surface stream water system for completely 5. The higher water system water use productivity was acquired with SSDI as contrasted and SDI framework for all water system medicines, and |
