Abstract
Sandy coastal in Yogyakarta have to develope land farming. Some problem to use its i.e soil
texture, soil structure, high permeability, defisiency of nutrient essential, leaching, low soil
surface , low water capacity and low nutrient essential fixation. The aim of this research was to
study the cultivars of sweet potato (Ipomoea batatas) under drought condition in sandy land. A
pot experiment was conducted from May to November 2013, in Experimental Station,
Agricultural Faculty of UPNVY. It was arranged in Split Plot Design. The Main Plot was the
sweet potato varieties: Beta -1, Beta -2, Papua Solossa, Sari, and Kidal. The Sub Plot was
the drought condition: normal water, water stress for 1 week on 20 and 60 days after plant.
Data were analyzed by anova and DMRT at 5%. The result showed that Kidal Variety had
best tuber number and tuber weight. Papua Solossa variety had lower sugar and starch than
another variety. Water stress had tuber number decreased but sugar and starch content
increased.
Key words: sweet potatoes, variety, water stress, sandy land
