“…Irrigation programming can greatly improve WUE. The adoption of methods to control the level of plant water stress (using soil tensiometers or other soil water sensors or calculation of water balance) can reduce the amount of water applied to the crop up to 53% (Muňoz-Carpena et al, 2008;Tognoni et al, 2002). However, comparative analyses among different strategies are limited (Table 1).…”

“…6), average irrigation efficiencies can vary from 25% to 50% for furrow irrigation systems, from 50% to 70% for the sprinkler systems, from 80% to 90% for the trickle (or drip) irrigation. If the amount of water is limited, sprinkler and drip methods can increase the irrigated area by 20% to 30% and 30% to 40%, respectively compared with furrow irrigation (Tognoni et al, 2002). In addition, irrigation water management with high flow turnouts and level basin irrigation systems can increase the efficiency of surface irrigation.…”

Irrigation is a vital component of the world agriculture. It is practiced worldwide on ≈270 million hectares and it consents to produce 40% of our total food. Agricultural water consumption accounts for 70% of total freshwater use. The competition for this precious resource is increasing tremendously. Therefore, it is becoming critically important to optimize agricultural water use efficiency (WUE) defined as the ratio of crop yield over the applied water. This requires a shift from maximizing productivity per unit of land area to maximizing productivity per unit of water consumed. To maximize WUE it is necessary to conserve water and to promote maximal crop growth. The former requires minimizing losses through runoff, seepage, evaporation, and transpiration by weeds. The latter objective may be accomplished by planting high-yielding crops/cultivars well adapted to local soil and climatic conditions. Optimizing growing conditions by proper timing of planting and harvesting, tillage, fertilization, and pest control also contribute to improve crop growth. Most of these techniques refer to proven technology, whose implementation and/or fine-tuning in current farming systems may tremendously improve water management efficiency. In this paper, after discussing the importance of irrigation in agriculture, we will introduce basic concepts that define crop WUE and will finally review the means to improve irrigation efficiency in field vegetable crop production.

“…These changes, whether used alone or in combination, are considered when proposing optimum management methods to enhance productivity and minimise the waste of both water and plant nutrients. Improving the uniformity of the irrigation system was a crucial objective, as highlighted by several studies (Upchurch et al, 2005;Tognoni et al, 2002;Lamm and Camp, 2007;Thompson and Doerge, 1995;Ayarset al, 1999;Mansour and Aljughaiman, 2020;Hellal et al, 2021;Mansour et al, 2019;Hu et al, 2019;Abdalla et al, 2019;Jiandong et al, 2019;Abd-Elmabod et al, 2019;Hellal et al, 2019).…”

Deficit irrigation strategies would require an accurate assessment of growth stage-specific stress tolerances for vegetable crops and optimal water management supported by advanced irrigation systems; i.e., able to promptly cope with crop water requirements at sensitive phenological stages However, in semiarid environments, the fulfillment of leaching requirements significantly limits the possibility of applying deficit irrigation criteria and reduces the WUE in irrigated vegetable production. The adoption of methods to control the level of plant water stress (using soil tensiometers or other soil water sensors or calculation of water balance) can reduce the amount of water applied to the crop up to 53%. Use of subsurface drip irrigation has progressed from being a novelty used only in experimental fields to an accepted method of irrigation for both tree and vegetable crops mentioned that subsurface drip irrigation on lettuce, tomato and sweet corn (Z. mays) has significantly increased yield and WUE in all these crops. Subsurface drip irrigation may increase WUE in semiarid environment under saline conditions by increasing yield. Our research goal is to suggest a framework could be utilized from natural and synthetic materials that could be used as soil and/or plant conditioners to maximize water use efficiency under drought conditions

“…It is acknowledged that growers often use more water and fertilizers than plants actually need. Today, only 30-50% of applied nitrogen fertilizer and ~45% of phosphorus fertilizer is taken up by crops (La Malfa and Leonardi;Stanghellini, 2003). A significant amount of the applied nitrogen and a smaller portion of the applied phosphorus is lost from agricultural fields.…”
