“…For the irrigation depth management, weight lysimeters of 100% evapotranspiration reposition were used as reference. During the first sowing day, the irrigation depth was calculated according to Mantovani et al (2009), considering a root system depth of 15 cm (soil depth in the vase), increasing the moisture of the soil to field capacity. From the second sowing day onwards, the irrigation depth was determined according to the evapotranspiration patch registered by the weight lysimeters, keeping the soil's moisture between the field capacity and the critical moisture levels, established by 50% of available water, and the values were registered during the entire culture cycle (Figure 1).…”

“…A uniformidade de distribuição de um sistema de irrigação vem a ser a disponibilidade da água irrigada nos emissores de forma mais igualitária possível para as plantas, sem risco de irrigação excessiva em algumas áreas enquanto outras não atingiram sua necessidade hídrica (MANTOVANI et al, 2009). O acompanhamento da uniformidade pode prevenir ou mostrar problemas na vazão do sistema.…”
