“…Notwithstanding the bad quality of the water (high pH, high EC) potatoes grow well and looked healthy ( Figure 26). The success of substituting pivot irrigation by subsurface fertigation in increasing water use efficiency and yields has already been reported in literature by several authors (Al-Ghobari et al, 2018, Hashem et al, 2018, O'Neill et al, 2008, Valentin et al, 2020 and also holds for the arid El Oued region. So, introduction of a subsurface system does have potential for increasing sustainability of potato growth.…”

The region of El Oued has been growing potatoes for about 15 years, and with 33.000 hectares potato cultivation, the region has turned into the largest potato production area of Algeria with two harvests per 12 months. However, the commonly used irrigation system is not sustainable due to high water waste. Therefore, a subsurface Decision Support System (DSS) fertigation method was introduced in this project to explore the opportunities for innovation towards more sustainability in potato production in a desert area. The smallholder potato producers of El Oued (in total around 2000) did not have the financial means to fully sponsor the project, but were willing to make land available for setting up, testing and demonstrating this innovative technique. This project, financed by the Dutch Ministry of Agriculture, Nature and Food Quality, via the Policy Support program has been carried out within the framework of the current and highly relevant theme "Sustainable agricultural development in a food system approach". In 2017, Wageningen UR Plant Research signed a collaboration agreement with the Algerian universities of El Oued, Biskra and Ouargla to work together on the innovation and sustainability of water use in potato cultivation in the Sahara. For the introduction of this DSS fertigation system Wageningen and the University of El Oued successfully cooperated and paved the way for future research cooperation.

“…Irrigated agricultural land is the primary user of water resources, representing roughly 70% of total water withdrawal [1]. However, the worldwide irrigated land area must be increased by more than 20%, and the total irrigated crop yield must be increased by 40% by 2025 to ensure food security for 8 billion people [2].…”

Water conservation strategies are becoming increasingly important as a result of the shortage of water and climate change. The purpose of this study is to address water-saving irrigation strategies by evaluating the effect of partial root drying irrigation (PRD) and Deficit Irrigation (DI) practice on the yield and water use efficiency of tomatoes (Shivam variety). The treatments were partial root drying (PRD) at 75% and 50% crop evapotranspiration, ETc (PRD25 and PRD50, respectively), and deficit irrigation (DI) at 75% and 50% of ETc (DI25 and DI50, respectively). The PRD practice requires wetting one half of the root zone and keeping the other half dry, consequently using less amount of irrigation water that was applied. In the successive irrigations, the wet and dry sides were alternated. Over a growing season after transplanting, the highest fruit yield was obtained under FULL irrigation (225 t ha-1). In comparison to deficit irrigation that received the same quantity of water, the PRD treatments produced an increased yield of 5–10%. PRD and DI irrigation improved WUE considerably, and that was 30.35% and 25.71% respectively higher than FI. Results suggest that PRD treatment may be an option in a water shortage.

“…Provide water as drop after drop on the surface soil to the plant during growing based on plant age in a low-pressure drip irrigation system which decreases costs and water irrigation and got high quality of crop (Tiwari et al, 1998). Hashem et al, (2018) showed that there is minimum water applied which plants need and water stress by using drip irrigation which led to low water losses and percolation deeply. The high yield of lettuce and cabbage crop was of 150% ETc.…”

This experiment studied water and nitrogen productivity for cabbage and lettuce under the shortage of nitrogen and irrigation water during growing cabbage (Saturn) and lettuce (Babura) plants. Mass production, nitrogen productivity, water productivity, chlorophyll A, chlorophyll B and total chlorophyll ,respectively were test under using four levels of nitrogen fertilization (0, 50, 100 and 150% of Nitrogen recommended) and also four levels of water regime (50%, 75%, 100% and 125% of ETc) in Libya conditions. The optimum conditions in drip irrigation greenhouse for crops grow were provided to give us high yield, quality production for cabbage and lettuce crops. Applying 100% N fertilization and 125% ETc to cabbage was the highest nitrogen productivity of 1132.3 kg yield /kg N, water productivity 17.32 kg/m 3 and mass production of 17.57 Mg/ha.The highest value of chlorophyll A, chlorophyll B and total chlorophyll obtained with 100%N and 100% ETc applied water for cabbage were (0.505, 0.753 and 1.258 mg/100gm) while for lettuce were (0.382, 0.299 and 0.681 mg/100 gm), respectively.
