Abstract

The aim of this research was to determine the deficit irrigation applications on upland rice (Oryza sativa L.) variety of inpago 9. This research was conducted in a plastic house, at the integrated field laboratory at the University of Lampung from November 2016 to March 2017. This research used a completely randomized design (CRD) with a of soil water content 4 levels, namely ID1 ((0-20)-100)% AW, ID2 ((0-20)-80)% AW, ID3 ((0-20)-60)% AW, ID4 ((0-20)-40)% AW, with five replicates. The result showed that deficit irrigation applications on upland rice (Oryza sativa L.) variety of inpago inpago 9 have an effect on the growth of plant heigth, number of leaves, number of tillers, number of panicle, the dry weight of plant, weight of root, and empety grain. Deficit irrigation applications on upland rice (Oryza sativa L.) varieties of inpago 9 has not effect on production of upland rice plants. The result yield response to water factor (Ky) showed (Ky > 1). Upland rice plant experience water stress at the treatment ID2 ((0-20)-80)% AW and ID3 ((0-20)-60)% AW. Upland rice was sensitive to defisit irrigation the highest water use productivity is ID1 ((0-20)-100)% AW with average productivity of 0,78 gram/liter. Keyword: deficit irrigation, growth phase, upland rice, and crop water productivit
