Organic and mineral fertilizer effects on growth and yield of cocoyam in a tropical Ultisol in South Eastern Nigeria
The performance of cocoyam (Colocasia esculenta L. Schott) to varying levels of cow dung and potassium fertilizer was investigated in 2012 and 2013 cropping seasons under field conditions at National Horticultural Research Institute (NIHORT), Imo State, Nigeria. The experiment was a 4 × 2 factorial arrangement in a randomized complete block design with three replications. The treatments were four levels of cow...

Evaluation of large seeded faba bean genotypes for agronomic performance in vertisol areas of Southern Tigray, Ethiopia
Thirty-two faba bean genotypes were evaluated for their yield and yield components in verstisol areas of Hashenge and Aiba in 2015. Alpha lattice design with two replications was used for the experiment. The Analysis of Variance showed highly significant differences (P<0.01) for thousand seed weight over locations. Based on this, genotype EH 06007-2 scored highest 1000 seed weight (1111 g) followed by EH 06088-6...

Allelopathic activity of extracts of Citharexylum spinosum L. from Tunisia
Allelopathic potential of Citharexylum spinosum L. (Verbenaceae) an exotic tree introduced in Tunisia many years ago was evaluated. Organic extracts using hexane, ethyl acetate and methanol solvents together with aqueous extracts at different concentrations were prepared from different parts of the plant (roots, stems, leaves and flowers). Yields in the 12 organic extracts together with their phenol contents were...

Pathogenic and genetic diversity in Puccinia hordei Otth in Australasia
Two PCR-fingerprinting primers, (GACA)4 and M13, were tested across 22 pathotypes of Puccinia hordei Otth collected from Australasia over a 30 year period, to assess their usefulness in revealing genetic variability in this pathogen. Both primers revealed polymorphisms among the pathotypes, with (GACA)4 generating a higher level of polymorphism. Molecular analyses revealed evidence of clonality among the P. hordei...

Tomato (Lycopersicon esculentum Mill.) varieties evaluation in Borana zone, Yabello district, southern Ethiopia
Tomato is one of the most important vegetable in Ethiopia as well as in the world in irrigated regions. It can be produced in a wide range of climatic conditions and many types of soils. Borana zone has potential to produce the crop, but not well done due to technical (production technology) and socio-economic problems. Among technical problem unavailability of seeds of adapted and improved tomato varieties is the most...

Agro-morphological characterization of Fonio millet accessions (Digitaria exilis Stapf.) collected from Boukoumbé, Northwest of Benin
Fonio is a cereal food of great socio-economic and cultural importance in south Sahara African Countries. Unfortunately, it is practically absent from National Agricultural Research Programs. To characterize the agro-morphological diversity of fonio ecotypes grown in Benin, twenty accessions collected from Boukoumbé were evaluated in a randomized complete block design (RCBD) with three replicates in Parakou....

Effect of seed source and seed age on yield and yield related traits of malt barley (Hordium vulgare L.) varieties at Central Arsi Highlands Ethiopia
The major constraints in fulfilling the growing demand of malt barley in Ethiopia are limited as a result of the selection of a favourable production environment and long-time seed storage for market advantages among others are few to mention. Besides, few research findings are available on evaluation of the potential differences across sites and crop management practices to meet malting and brewery industry quality...
