Coffee leaf damaging insects’ occurrence in the forest coffee ecosystem of southwestern Ethiopia

Insects are diverse and abundant in forest ecosystems, but poorly documented in afromontane rainforests in Southwestern Ethiopia where Coffea arabica L. originated and is distributed worldwide. Therefore, the present study was initiated to study the occurrence of coffee leaf damaging insect pests in the afromontane rainforest of southwestern Ethiopia. Accordingly, surveys on insect pest of coffee were conducted to...

Physiological nutrient use efficiency of banana hybrids across agro ecological regions in Uganda

Banana is an important source of food and income for millions of people in sub-Saharan Africa and Uganda in particular. This makes it one of the most important food crops in the country. However, production is limited by both biotic and abiotic constraints. Among the biotic constraints, is the decline in soil fertility. In addressing some of these biotic and abiotic constraints, banana breeding programmes are developing...

Genetic variability and divergence of seed traits and seed germination of five provenances of Faidherbia albida (Delile) A. Chev

Establishment of Faidherbia albida trees on farm is often difficult despite the plant survival adaptive mechanisms such as drought and disease resistance. Adoption of the tree to agroforestry systems is also limited due to lack of knowledge on genetic variation of its provenances. Morphological charac-terization of F. albida provenances is therefore necessary to screen for natural genetic variation in seeds traits for...
