Utilization of wild relatives for maize (Zea mays L.) improvement
Experimentally induced introgression and selection during domestication and maize (Zea mays L.) improvement involved selection of specific alleles at genes controlling morphological and agronomic traits, resulting in reduced genetic diversity relative to unselected genes. The plant breeder would have to extend crosses to the wild relatives to introduce novel alleles and diversify the genetic base of elite breeding...

Assessment of genetic diversity among released and elite Ethiopian barley genotypes using simple sequence repeat (SSR) markers
Barley is a major cereal grown widely and used in several food products, beverage production and animal feed. Being the fourth most important cereal crop in the world and the fifth rank in Ethiopia, it is a cash crop and used as a source of malt by the brewery industries, as food for human and feed for animals. Genetic diversity assessment is a key component in breeding programs. High level of polymorphism,...

Rhizobium inoculation and sulphur fertilizer improved yield, nutrients uptake and protein quality of soybean (Glysine max L.) varieties on Nitisols of Assosa area, Western Ethiopia
A greenhouse experiment was conducted to study the effect of inoculation of Rhizobium strain and sulphur fertilization on seed and straw yields, nutrients uptake and seedquality protein of two soybean (Glysine max L.) varieties. The experiment consisted of four levels of S (0, 20, 30 and 40 kgha-1), three Rhizobium strains (MAR-1495, SB-6-1-A2and TAL-379) and two soybean varieties (Belessa-95 and Wollo) combined...

Response of Cyperus papyrus productivity to changes in relative humidity, temperature and photosynthetically active radiation
Ecosystem development is related to climatic conditions. To assess the effect of seasonal changes in climate factors on papyrus ecosystem development, community biomass was estimated non-destructively and climate factors recorded in the wetland. Absolute aerial biomass and productivity were not significantly different between wet and dry seasons. Although there was significant vapour pressure deficit change over the...

Variation of leaf and fruit characteristics of Vitellaria paradoxa (shea tree) according to agronomical performance along south-north climatic gradient in Mali
Shea trees identified for agronomical performances were compared through leaf and fruit characteristics. Seventy adult trees were selected using purposive sampling from seven sites along a south-north climatic gradient covering four agro-climatic zones. The effects of two factors (type of performance and site) on leaf and fruit parameters were investigated. Results showed significant effect of the type of the...

Fall management of fleabane based on glyphosate+2, 4-D, MSMA and glufosinate applied isolated or in tank mixture with residual herbicides
Fleabane (Conyza spp.) has spread in no-tillage areas of Paraná State (PR), Brazil, and currently represents one of the main challenges related to weed control, particularly during off-season period. For this purpose, two experiments were carried out in Campina da Lagoa (PR) and Floresta (PR) with the aim of assessing the efficacy of herbicide treatments applied to fleabane areas during the off-season period...

Ethnobotanical survey of medicinal plants used for treating preschool children anemia in an urban setting, Douala-Cameroon
Anemia is one of the most widespread public health problems which mainly affect preschool children. Its prevalence is 60% in Cameroon and due to poverty, many patients turn towards medicinal plants for treatment. This study was designed to compile plants used for the treatment of anemia in the Littoral Region (Douala) of Cameroon and classify them based on their use. An ethnobotanical survey was carried out in December...

Sucker multiplication in plantain using chicken manure as a substrate supplement
This study was carried out to evaluate the response of chicken manure (CM) as a substrate supplement for sucker multiplication and its effect on varietal differences in two subgroups of plantain (Apantu, a False Horn and Apem, a French plantain), using well-developed sword suckers. The research was laid out in a 2 x 2 factorial randomized complete block design with two substrates (chicken manure/sawdust mix and sole...

Pod yield stability and adaptation of groundnut (Arachis hypogaea L.) genotypes evaluated in multi-environmental trials in Zimbabwe
Twenty-five groundnut genotypes were evaluated to identify the types of Genotype-Environment-Interaction (GEI) for pod yield. Genotypes were evaluated under multi-environmental yield trial conducted in 2013/14 season at five environments. The objectives of the experiment were to: identify genotypes with high pod yield stability, to identify genotypes with specific/wide adaptation, identify groundnut mega environments...
