“…Spunta seed is produced in Algeria for the winter season. Other varieties are Désirée, Fabula, Ultra (Houben, 2017). For the spring season seed is imported from abroad (mainly from the Netherlands).…”

“…A large percentage of the potatoes is being lost in the post-harvest phase (Hanafi, 1999;Houben, 2017), but no clear figures are available for El Oued. Part of the loss occurs during (manual) harvest, further losses occur during transportation due to inadequate packaging and transportation as well as infrastructure problems.…”

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.

“…It is a complex of strains that have developed through recombination and accumulation of mutations, allowing the virus to successfully adapt to new potato cultivars [17]. Some genetically modified strains of PVY cause similar necrotic symptoms known as "potato tuber ringspot disease" that caused heavy economic loss in potato production [18,19].…”

Potato virus Y (PVY) causes serious loss in the yield and quality of potatoes. The effect of chitosan nanoparticles (CS-NPs) on the regeneration response and production of PVY-free plants under in vitro conditions was studied. Murashige and Skoog (MS) medium supplemented with 0.1 mg L−1 Gibberellic acid (GA3), 0.1 mg L−1 Naphthalene acetic acid (NAA) and 500 mg L−1 malt extract was used for regeneration of plantlets from sprouts. Double Antibody Sandwich Enzyme-Linked Immunosorbent Assay (DAS-ELISA) and Reverse Transcript Polymerase Chain Reaction (RT-PCR) was used for virus indexing of the mother plant and in vitro-regenerated plantlets. Explants of PVY positive potato plants were cultured on same medium amended with 100, 200, 250, and 300 mg L−1 of (CS-NPs). Shoot regeneration decreased from 100 to 200 mg L−1 as the concentrations of antiviral (CS-NPs) up to 250 mg L−1. It was decreased with the increase in the concentration of the antiviral (CS-NPs) up to 300 mg L−1. Antiviral (CS-NPs) at the concentration of 250 mg L−1 showed a positive effect on shoot regeneration. In vitro-regenerated plantlets were virus free and tested negative in both ELISA and RT-PCR. The level of 100 mg L−1 of (CS_NPs) produced 38.8% PVY-free plants and 30.50% of cultures showed shoot regeneration. The level of 200 mg L−1 of (CS-NPs) produced 49.6% PVY-free plants while 46.8% of cultures showed shoot regeneration. The level of 250 mg L−1 of (CS-NPs) was the most effective and produced 100.0% PVY-free plants and 100.0% of cultures showed shoot regeneration. Histopathological changes simultaneously with elucidation of resistance and growth enhancement were evident in the treated plants with (CS-NPs) than those untreated control. In conclusion, (CS-NPs) treatment is an effective tool to produce PVY-free sprouts explants and has potential for producing virus-free planting material for the potato industry.
