The objective of this work was to evaluate crop growth, canopy development and yield of
soybean plants submitted to different irrigation regimes. The experiment was conducted in the
experimental area of the Agricultural Engineering Department at the Federal University of Santa
Maria, RS, Brazil, during the 2001/02 growing season. A completely randomized design, with four
treatments and two replications was used. The irrigation management treatments were: 20, 40, 60
and 80 mm of cumulative maximum crop evapotranspiration, estimated by Penman-Monteith
equation, as the irrigation depth trigger. After reaching these values, irrigation application was based
on daily maximum crop evapotranspiration. The experimental site was protected against rainfall
through an arch rain shelter structure. Soybean was sown using the no-tillage system, with 0.45 m
rows space and a plant density of about 155,000 plants ha-1.
