Abstract:
Lettuce (Lactuca Sativa) is the most widely grown all green leaf salad crops in the world. It probably originated in east and introduced to Mediterranean at an early date. Lettuce belongs to aesteraceae family. Comparatively, the germination rate of lettuce in our country is very low by several factors which influence the germination of lettuce. Among this optimum sowing depth are very important. The objective of present study was determination of the optimum planting depth that gives comparatively the best germination. Laboratory experiments were conducted during 2019 at wolaita sodo university Horticultural laboratory room, southern Ethiopia. Lettuce (Lactuca sativa) seeds were planted in mixed media in plastic pots at depth of 0, 2, 4 and 6cm. Complete block design (CBD) was used for designing the experiment. The result this study was 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.
