Acclimatization and performance evaluations of sweetpotato (Ipomoea batatas L. Lam) on yield and yield components in different agro-ecologies of Northern Ethiopia

The study is aimed at evaluating the genotype by environment interactions (GEI) on acclimatization of sweetpotato genotypes to the farmers’ field conditions. A field evaluation was done on six sweetpotato genotypes planted in RCBD, three replications in three different agro-ecologies. These genotypes were previously (2012, 2014) tested for yield performance in the same environment. Data collected were subjected to...

Mycorrhiza co-association with Aspilia pluriseta Schweif. and phosphorus uptake effects on growth of gadam sorghum in the semi-arid lower Eastern Kenya

Mycorrhiza fungi are important components of soil microbiota in the rhizosphere and greatly influence the uptake of mineral elements by plants. A greenhouse experiment was conducted at the University of Embu to evaluate effect of Aspilia pluriseta rhizosphere mycorrhiza on phosphorus uptake by gadam sorghum. Pots were filled with soil from a predetermined source in the semi-arid Gakurungu, Tunyai and Kanyuambora regions...
