摘要: Two field experiments, organized in randomized complete block design, were conducted 2005 and 2006 farming seasons at Nyankpala the Northern Region of Ghana to investigate effects planting depth (1, 2, 4, 6 8 cm) land preparation methods (flat field, mounding ridging) on crop establishment (percentage number established plants) grain yield soybean (Glycine max cv. Anidaso). In season results indicated that increased from 1 cm (97.75%), reached a peak 4 (98.82%) declined through 6–8 (94.15%) under flat condition. Nodule formation was high between 2 cm. Generally, pods decreased with increasing plant depth. The values for 1, depths 4.25, 4.22, 3.87, 3.26 3.12 t/ha, respectively. season, ridging gave highest 97.77%. recorded mound (197 per plant) followed by ridge (189 (143 plant). This pod characteristic reflected 6.14 5.95 t/ha 4.07 mound, flat, study revealed good optimum northern could be done mounds or ridges Ridging may preferred because it can easily prepared mechanically using tractor save time labour.
