Abstract

Production of soybean is unbalanced. Increasing number and need of the population is one causes of soybeans
scarcity. One factor needs to be considered in soybean cultivation is crop water requirement. This study aims to
determine thewater requirement of soybean bymeasuring evapotranspiration of soybeanlocal varieties directly
by lysimeter (2x3x1)meters. Fieldobservations carried out attwo lysimeters tomeasure crop evapotranspiration
(ETc) variety of Tanggamus and one plot planted with grass as standard evapotranspiration (potential). The
results showed that total soybeancropwater requirement (ETc) forTanggamus is 490.02mmor 6.3mm/hari and
the total per-phase ETc is 5.4; 4.8; 6.7; 7.9 mm/hari. Soybean crop coefficient values (Kc) in the early growth
phase, active vegetative, fertilization or seed pod filling, and maturity for the varieties Tanggamus is 0:48; 0.69;
0.9; 0.78.
