Effects of reduced spacing on maize productivity, CO2 assimilation and gas exchange
The objective of this study is to evaluate the interference of reduced spacing in the physiological and characteristics production components of maize hybrids (Zea mays L.). Four line spacings (95, 80, 60 and 40 cm) were tested using three commercial hybrids (H1, H2 and H3) in Senador Guiomard, Acre, Brazil. The experimental design of randomized complete blocks was used in subdivided plots. The experiment lasted four...

Management and organization of shina-hamusit and selamko irrigation schemes to preliminary assessment in South Gondar Zone, Ethiopia
The utilization of small-scale irrigation schemes plays a significant role in addressing food security problems as a supplementary with rain-fed or irrigation agriculture in the basin and as a whole in the country. The conveyance efficiency values at Shina-Hamusit was 73%, while at Selamko it was 59%. These values showed that the conveyance loss is huge in both irrigation schemes, especially at Selamko that has canals...

Nutrient cycling in multifunctional agroecosystems with the use of plant cocktail as cover crop and green manure in the semi-arid
Plant cocktails used as cover crop present a significant multifunctional resource compared to monoculture, which may increase functional diversity within crop rotation and is particularly effective for designing mixtures with characteristics that increase the multifunctionality and sustainability of the agroecosystem. The objective was to evaluate sustainable agroecosystems models that improve the efficiency of nutrient...

Socio-economic aspects related to feeding resources and practices in selected intensive dairy farms in Central Ethiopia
Dairy cattle productivity is affected by many factors such as genetics, infectious diseases, husbandry and diet. Fodder resources, fodder availability and feeding strategies were assessed by means of questionnaires and interviews in seventeen dairy farms in Addis Ababa, Sendafa and Debre Zeit. Nutrient content was analyzed from hay sample. The farms were categorized as small, medium or large. Nutrient content, as well...

Efficiency of Trichoderma asperellum UFT 201 as plant growth promoter in soybean
Filamentous fungi of the genus Trichoderma are known for their activity as plant growth promoters. The objective of this work was to evaluate the efficiency of the Trichoderma asperellum UFT 201 strain as a plant growth promoter in soybean. The ability of phosphate solubilization, indole acetic acid synthesis and the effect on soybean plant growth under greenhouse conditions were evaluated in four experiments. In vitro...

Performance of garlic cultivars under rain-fed cultivation practice at South Gondar Zone, Ethiopia
Garlic (Allium sativum L.) is an important edible bulbous crop with unique culinary and medicinal purposes. It is a major cash crop widely cultivated in Libokemkem and other districts of South Gondar zone of Amhara Region in Ethiopia. However, productivity of garlic in Ethiopia in general and in South Gondar Zone in particular is very low largely due to the use of unimproved local cultivars and traditional cultural...

Women involvement in the fishery activities of two coastal communities in Sierra Leone
Women make up an important part of the fishing sector and play critical roles, particularly, in small-scale fisheries and increasingly in capture fishing and other activities. However, the roles of women are often undervalued due to the lack of attention to gender roles in fisheries, especially in Africa. This research was therefore motivated to investigate the roles of women in two coastal communities of Sierra Leone....
