Impact of fungicides on the performance of ten varieties of 4 potato newly introduced in Algeria

Abstract

The potato is an increasingly important food in Algeria. Domestic production has  increased in  recent years due to high consumption. Faced with this increase in  consumption, it is necessary  to produce quality potatoes from the point of production yield. The present work aims to study the variability of potato production in relation to the production areas. On the other hand, newly introduced variety trials are conducted treated with fungicides. The yield results  show that the Challenger and Synergy white-skinned varieties are the most profitable, the  production has reached more than 350Qx / ha with a yield index greater than 100%, they have  shown resistance to fungal  diseases in contrast to varieties Lusa and Senna, which reacted  negatively even with the foliar treatment, their yield is very low.
