    Abstract: This study investigated the transpiration (TR) response to (i) diurnal changes of vapor pressure deficit (VPD) and (ii) soil dry down in four maize hybrids contrasting for yield performance under drought stress in the field. These four hybrids included a popular local variety P3K and a commercial check SC303 that were found to be drought susceptibl... Show More

    Abstract: Common bean is grown for its high nutritive, medicinal and market value in Ethiopia. Lack of soil nutrients and moisture are production constraints in central common bean producing regions of Ethiopia. Field experiments were conducted on two common bean varieties Awash Melka and Mexican 142 at Shewarobit and Ataye in 2016 and 2017 main cropping sea... Show More

    Abstract: The pea aphid (Acyrthosiphon pisum Harris) is an economically important insect pest of lentil in Ethiopia. The development of pea aphid resistant lentil genotypes with known resistance mechanism is an economical and effective way to manage this pest. Hence, the current study was conducted to determine the mechanisms (antibiosis, antixenosis, and to... Show More
