Effect of Inorganic Fertilizer and Sowing Methods on Tef (Eragrostistef (Zucc.) Trotter) Production in Ethiopia: Review

Résumé

Tef [Eragrostistef (Zucc.) Trotter] is one of the major small cereal crops in Ethiopia in terms of production and consumption. But in Ethiopia, it is yield low as compared with other major cereal crops growing due to many production constraints such as low soil fertility, lack of appropriate management practices, minimum use of improved varieties, and lack of location specific fertilizer recommendation. Synthetic fertilizer and sowing method have great role on yield and yield components of Tef. So, objective of this study is to review the effects of inorganic fertilizer and sowing methods on yield and yield components of Tef in Ethiopia. Most research work so far focused on NP requirements of crops, but limited information is available on various sources of fertilizers like S, Zn, B and other. Tef responds differently to fertilizer rates and types depending on soil type and cultivars. Application of other sources of nutrients beyond urea and DAP, especially those containing S, Zn, B and other micro-nutrients and different method of sowing could increase Tef crop production and productivity in different area and different agro ecology. Therefore, to increase the production and productivity of tef in country use of Synthetic fertilizer and row sowing are important.
