Abstract

The potato is one of the most important plant food, forage and industrial. In the industry potato is an important raw material for sp irits, starch, dextrin and glucose. The potato ensure high quantity of protein (310 kg / ha) and e nergy (12 896 Mcal / ha), situated in second place after barley and breweries. Given the importance of potato in food and feed, in Romania between 1998 - 2001 he ensured the largest quantity of dry substance, protein and energy per hectare, in favorable climatic conditions for this crop. In the context of sustainable agriculture, potato is more valuable talking about the agronomic, economic and ecological indicators: the environment, consumer health protection, landscape quality.This study presents researches about technology in irrigated potato crop, adapted at the global warmin g and aridisation in traditional farms in central Transylvania, Somes Plateau, the Letca zone. The re sults of this study shows the dangerous periods of severe drought in recent years, which may endang er potato and they are justifying the irrigation technology development on zone small and medium farms. Analyzing the results obtained in dry years 2011-2012, for the two studied Romanian varieties (Redsec and Milenium), we founded provided production increases by applying irrigatio n, higher production was achieved in 2011, compared with yields of 2012 disaster situations fr equently recorded in the country.
