Angular leafspot (ALS), caused by the fungus, Pseudocercospora griseola, is one of the most important disease of common bean in Tanzania. Breeding for resistance to this disease is complicated by the variable nature of the pathogen. In Tanzania, a thorough analysis of the variability of this pathogen is lacking which limits breeding for durable resistance. This work aimed at characterizing P. griseola in relation to its...

Dekoko is a cool-season food legume cultivated in Tigray, Northern Ethiopia. It is highly appreciated by the local people for its taste and high market value. Yields of Dekoko, however, are limited by improper planting spacing. Thus, an experiment was conducted in 2013 and 2014 cropping seasons to determine the appropriate planting spacing of Dekoko that maximizes its productivity under rain fed conditions. Treatments...

A successful application of humic acids and diazotrophic bacteria in corn represents a potential that collaborates to break the current energetic consumption paradigm, which is based on unsustainable fossil sources. Thus, this study aimed to quantify the contribution of diazotrophic bacteria in association with humic acids and nitrogen (N) in corn, in an experiment conducted under controlled conditions in a greenhouse....

Four Caladium bicolor variants collected from different parts of Nigeria were subjected to anatomical comparison to enhance the taxonomic status of the species. Fresh samples (leaf and petiole) of these variants were fixed in formalin, acetic acid and alcohol (FAA), dehydrated in alcohol series, peeled or sectioned. Peeled specimens were stained with safranin, while sectioned ones were stained with Alcian blue and... Read more.

A disease test at different leaf layers (plant stages) of homologous rust and heterologous rust species were studied. The result from homologous rust species showed that those quantitative trait loci (QTLs) (Rphq2 and Rphq11) which were effective at seedling stage were also effective across all plant stages with gradually decreasing effect as plants grew older. Rphq3 which had consistent effect in all leaf layers... Read more.
