“…The evergreen canopy and high lateral root density nature (António Fabião et al, 1990) makes it to be competitive tree than the native once (Armel Thongo M' Bou et al, 2008;Fabiao et al, 1994;Jaleta et al, 2017) To manage and reduce these ecological impacts, and maximize the productivities of the practices, alternative options like above and belowground tree and soil management (A Fabião et al, 2002;Khan et al, 2020;Zewdie, 2008), inter and intra spacing as well as alignment management of plantation (Kidanu et al, 2005;Prasad et al, 2010) becoming mandatory. Because as studies revealed, the effects of Eucalyptus globules on adjacent crop yield mainly depend on tree line orientation (Carneiro et al, 2013;Kidanu et al, 2005), tree age, and canopy cover (Kidanu et al, 2005;Zewdie, 2008). According to Nuno & Manuel, (1996) and Kidanu et al (2005) applying proper soil management substantially increased crop yield, availability of soil nutrients, and microbial population dynamics under Eucalyptus globules based agroforestry practice.…”

The expansion of Eucalyptus globules boundary plantation (EGBP) along farm boundaries considered to have effects on yield of underneath crops. Tree root pruning or trench is a potential tool for managing belowground competition. We evaluated aspect and trench distance effect of EGBP on barley yield and soil physicochemical properties in Gummer woreda, central Ethiopia. Two months before sowing, on one side of each aspect of EGBP trenches were prepared at distances of 0.5m, 1m and 1.5m using split-split plot design with three replications. At 1.5m trench distance, the North faced field showed 20.4%to 31.2% additional yield variation respectto South, East and West faced fields. Also 15.2% to 43% additional yield was observed as the field distance from EGBP increased from 3m to 12m. Relative to un-trenched field, trenched fields showed 31.9% to 73.4%additional yield variations. Regarding to soil physicochemical properties, aspect of EGBP had no significant effect. However, except for texture, pH and extractable potassium, trench showed a significant difference on soil organic matter, total nitrogen, available Phosphors and CEC status. Relative to un-trenched fields of 6m and 9m, 1.5 m trenched field of 3m field distance showed 48 % and 15% additional yield variations. That means root trench minimized on average 24% of the field distance effect of EGBP on barley yield. Therefore, root pruning at 1.5m distance from EGBP using 0.5m x 0.5 m trench is an applicable and advisable method that will help farmers to maximize barley yield with higher land-use efficiency.
