Abstract

The objective of this research is to find out the influence of evapotranspiration deficit toward plants growth and
water use efficiency of three soybean varieties (Glycine max. (L) Merr.). This research was conducted in the
greenhouse, integrated laboratory of Agriculture Faculty, Lampung University on November, 2013 to January,
2014. This research used a complity randomized design consisting two treatment factors with three times
repetition. The fisrt factor was evapotranspiration deficit (E) consisting of E1 (1.0), E2 (0.8), and E3 (0.6), and
E4 (0.4). The second factorwas variety (V) consisting of Tanggamus (V1), Kaba (V2), andWillis (V3). The result
of research showedthat evapotranspiration deficit and varietywas significantly differentwhereas the interaction
was not significantly different at all growth components, production andwater use efficiency .The highest result
productionwasWiliis (V3) and Kaba (V2) on E1 (1.0) 12.33 gr/pot. The highest value ofwater use efficiencywas
Willis (V3).
