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

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
