ABSTRACT

Jute mallow (Corchorus olitorius) is one of the common green leafy vegetables used widely throughout Nigeria locally called Ewedu. Jute is mostly propagated by seeds except in the case of research where tissue culture can be employed. Cuttings may also be used for propagation. The demand for this crop is all year-round. Its utilization is not limited to consumption. It is also an industrial raw material for paper industries and other Bast fiber utilization industries. Despite the high demand for jute, it production is marred by a variety of problems however, poor seed germination is one of the most important. Although, there has been various attempt and research to solve this issues and more research is still ongoing. Most of these pre-sowing treatment aid faster germination but in-turn still damages the embryo. Thus, this study aims to compare the already existing methods to the newly introduced ones. Three pre-sowing treatment was used, which included manual scarification, warm water for 10 seconds and dry heat of 70℃  for 10seconds. The highest germination was recorded in warm water for 10seconds. For sowing depth, 2cm and 5cm was used where 2cm showed the best germination percentage and germination energy. It can thus be concluded that warm water for 10 seconds and sowing depth of 2cm are the best treatments
