Abstract : Seedling emergence and crop production is as a result of many factors, these factors include temperature, water availability, seed depth and so on. Seedling emergence is a function of seed size and depth of sowing during cultivation. It is also influenced by the types of soil. Thus, it is on this basis that this study tends to determine the effects of soil depths and soil types on emergence of Celosia argentea, Amaranthus viridis and Corchorus olitorus. The seeds Celosia argentea, Amaranthus viridis and Corchorus olitorus were obtained from Agricultural Input Supply, Agric Bus-Stop, Ojo- Lagos State, Nigeria and seeds were sown in bowls having soil as growth medium respectively. The seeds were subjected to emergent test at different depths (0cm, 1.5cm, 2.5cm and 4.0cm) and emergent records were taken for ten days. Also, the seeds were sown in loam, clay and sandy soils respectively. The results show that Celosia argentea emerged best at the surface (0cm) while Amaranthus viridis and Corchorus olitorus emerged best at 1.5cm depths respectively. However, loamy soil had the best emergent performance compared to clay and sandy soils for all the seeds. It is therefore concluded that, for effective and efficient crop production, the best soil depth and soil type should be used.
