Farmers’ perception of a biological control agent, Oecophylla longinoda Latreille (Hymenoptera: Formicidae) and its effects on the quality of citrus fruits in Ghana

The red weaver ant, Oecophylla longinoda Latreille is a predator of many insect pests of tree crops and its presence in orchards is perceived to result in improved fruit quality. This study therefore sought to investigate farmers’ perception of O. longinoda as a biological control agent for insect pests of citrus and its effect on fruit quality. A questionnaire-based survey was first used to investigate...

Impact of pasture herbicides on the seedling growth response of three tall fescue varieties

Chemical application is a viable and popular method for weed control, but the effectiveness of various herbicides depends on the target weed. The objectives of this study were to determine the appropriate herbicide for three tall fescue varieties that either do or do not contain endophytic fungi. Plants were split into six herbicide treatments and an untreated control for 7, 14, 21, and 28 days in a randomized complete...

Meloidogyne incognita resistant strains of leaf lettuce

The root-knot nematode is a major problem for commercial lettuce cultivation because it affects the market quality of the final product. The objective of this study was to select strains of butter-leaf lettuce resistant to Meloidogyne incognita spp. with good agronomic performance for further cultivar trials. Three field experiments were conducted on the premises of Instituto Agronômico de Pernambuco (IPA-PE) and...

Valorization of Jatropha curcas seed cake into different kinds of compost and effect of these composts on cabbage yield in Togo

Jatropha curcas L. is a plant species from the family of Euphorbiaceae. The extraction of oil from its seeds produces a cake for which its accumulation causes different environmental problems related to solid waste management. The valorization of this cake into compost could be a contribution to solving this problem. Therefore different types of compost were made with J. curcas seed cake associated with animal feces...

Influence of harvest time in accumulation of biomass between cassava cultivars

Lack of cultivar adapted to the planting area, as the ideal harvest period undertakes the productive potential of cassava. The study was conducted to evaluate the influence of different harvest seasons on total production of fresh and dry weight of four cassava cultivars. The used cultivars were: Branca de Santa Catarina (BSC), IAC 13, IAC 14-18 and Fiber that they were planted on 09/20/11 at the headquarters of the...

Enhancing social-ecological resilience through social learning: A case study of communal pasture management in the Highlands of Ethiopia

Social learning processes can play an important role in enabling communities to sustainably manage the natural resources they depend upon. We examine how a community in the highlands of Ethiopia has succeeded to manage its communal pasture sustainably over the past decades. We identified three processes that played a key role in enabling the community to take the window of opportunity offered by a radical policy change...

Determination of nutrient composition and organoleptic evaluation of bread produced from composite flours of wheat and beans

The study was conducted to compare the chemical composition and organoleptic evaluation of 5 bread samples (B1, B2, B3, B4 and B5). The bread samples were made from composite flours of wheat and fermented ground bean flours (70:30), (60:40), wheat and fermented brown-eyed bean flours (70:30), (60:40) and 100% wheat flour. The samples were processed and milled into fine flours. The flours were used to produce different...
