Abstract

In recent days there is change in trend of rainfall across the country where its starts in May and ceases early-to-mid September. This implies that adjusting cropping calendar is vital to adapt to the changing climate of the area. The field experiments were carried out at Debre Zeit Agricultural Research Center (DZARC) and Alemtena during the main cropping season from 2015 to 2017 to determine appropriate sowing date for tef varieties. The treatments consisted of three sowing date (early-July, mid-July, and late-July) and two recently released tef varieties (Kora and Boset). The experiment was laid out in a randomized complete block design in a factorial arrangement and replicated four times per treatment. Data were taken crop growth, biomass yield, and grain yield. Combined analysis of variance overs years showed that interaction effects of variety by sowing date were significant effects on plant height and panicle length at DZAR while, at Alemtena, plant height and panicle length was significantly affected only by variety. At both location biomass and grain yield of tef was significantly affected by variety and sowing date interaction. Among the different sowing date treatments, sowing of Kora variety in mid-July showed the highest mean biomass yield (8444.4 kg/ha and grain yield (1813.3 kg/ha) at DZARC but at Alemtena the highest biomass (9766.2 kg/ha) and grain yield (1595.7 kg/ha) was achieved Kora was sown in earl-July. However, sowing of Boset variety at mid-July was comparable yield advantages. Over all, based on the result of this study, sowing of mid-July and early-July would be recommended for the mentioned variety production at DZARC and Alemtena, respectively.
