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"
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.
