The depth of sowing is important in maximizing the potential of seedling emergence and crop growth. Too shallow sowing results in poor germination due to inadequate soil moisture at the top soil layer. On the other hand, deep sowing can also significantly reduce crop emergence and growth. It would create the emergence seedling had less performance and productive which means when it is too deep is not able lift its cotyledon above the soil, soil born diseases and insects have damage their seedling. These factors limit the crop yield potential right from the starting of the growing. An important objective of seeding for improved crop performance is putting seeds at a desired depth. Seeds should be sown at a depth that increases the likelihood of germination, emergence and improved growth. Thus, this study examined the effect of different sowing depths on germination and growth faba bean (Gorra variety) at Fitche, central Ethiopia. A randomized complete block design arrangement with three replications was used for the experiment. The treatments consisted of 4, 6, 8, 10 and 12 cm sowing depths. Analysis of variance showed significant effect of depth of sowing on Gorra faba bean variety germination and growth. Sowing at a depth of 8 cm showed better germination percentage, fast emergence and produced the tallest plant having the highest number of leaves per plant. 12 cm sowing depth (i.e. the deepest sowing depth) showed poor germination percentage (65.7%), late emergence (7 days) and gave the shortest plant (13.53 cm) with the lowest number of leaves per plant (21). Therefore, better germination, emergence and improved growth, Gorra faba bean variety should be sown at a depth of 8 cm.
