Fig. 2. Soil water volume for 0 to 90 cm as affected by tillage and planting treatments in (a) 2003 and (b) 2004 at Abergelle in northern Ethiopia. Y-bars equal LSD0.05 appropriate for that sampling date. Flat plant = planting with a flat soil surface. TR = tied-ridging; WAP = weeks after planting; IF and OR = in-furrow and on-ridge planting, respectively. Shilshalo = a traditional ridging practice conducted 4 wk after planting.
