Determination of crop coefficient of local barley cultivar in Tigray, Northern Ethiopia using drums

Abstract: 
Barley is a major staple food crop in the highlands of northern Ethiopia. The crop is used for preparing various types of traditional foods. Barley yield over the northern Ethiopia is severely affected mainly due to water stress. To minimize the problem, household ponds were constructed to supplement rain water. However management of this irrigation water is very poor because the crop coefficient of the local barley is not known. To measure crop coefficient, lysimeters are needed. Unfortunately they are not available in Ethiopia. A locally made lysimeter was designed and installed in 2010 in northern Ethiopia to measure the evapotranspiration and determine the crop coefficient for barley. Preliminary results showed that the seasonal evapotranspiration of barley was 375 mm which is similar to many other cereal crops in the region. The one year single crop coefficient values for early, vegetative, mid and late crop stages were 0.7, 0.85 1.05 and 0.6 respectively.
L’orge est une culture alimentaire de base importante dans les montagnes du nord de l’Ethiopie. Elle est utilisée pour la préparation de différents types d’aliments traditionnels. La production de l’orge dans le nord de l’Ethiopie est gravement affectée principalement par le stress hydrique. Afin de minimiser le problème, les étangs des ménages ont été construits pour suppléer l’eau de pluie. Cependant la gestion de cette eau d’irrigation est très faible parce que le coefficient cultural de l’orge locale n’est pas connu. Pour mesurer le coefficient cultural, les lysimètres sont nécessaires. Malheureusement, ils ne sont pas disponibles en Ethiopie. Un lysimètre fabriqué localement a été conçu et installé en 2010 dans le nord de l’Ethiopie pour mesurer l’évapotranspiration et déterminer le coefficient cultural pour l’orge. Les résultats préliminaires ont montré que l’évapotranspiration saisonnière de l’orge a été de 375 mm qui est semblable à beaucoup d’autres cultures céréalières dans la région. Les valeurs du coefficient cultural pour une seule année concernant les stades culturaux précoce, végétatif, moyen et récent ont été de 0.7, 0.85 ,1.05 et 0.6 respectivement.

About the RUFORUM 2010 Biennal Conference
"The 2010 RUFORUM Biennial Conference was the second in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholders in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. This record contains an extended abstract accepted under the theme of Plant Breeding"
