Palm Oil and Rubber Price and Trader’s Behavior at International towards Local Level
(2021-06-17)The dynamics in trade are inseparable from the influence of policies, prices and the role of traders themselves. Although trade policies of exporting and importing countries differ, generally the policies support the ... -
Performance of organic and conventional crop varieties and species mixtures under stress
(2022-02-24)The conservation of agrobiodiversity is considered a priority to ensure the sustainability and sovereignty of food production under changing climatic and socio-economic conditions. In this context, substantial value is ... -
Performance of the Fruit Crop Industry in Ghana: Empirical Results and Policy Implications
(2014-12-11)This study investigates the causes of declining output performance in the Ghanaian fruit pro-duction industry. Average industrial output level is lagging far behind that of competing na-tions (for instance, the productivity ... -
Performance of underutilized forage legumes as an alternative to Trifolium repens under drought stress: yield, water utilization and nutritive value
(2013-05-31)Grassland with a high productivity and fodder quality forms the basis for ruminant nutrition. In grassland swards with no or little input of nitrogen (N) from mineral fertiliser or manure, legumes are essential for ... -
Pflanze-Herbivore-Parasitoid Interaktionen auf Wildrosenarten und ihren Hybriden entlang eines geographischen Gradienten
(2006-03-24)Phenotypes of closely related plant species have been shown to affect higher trophic levels. Multitrophic interactions between host plant species, herbivores and natural enemies may change depending on phenotypic ... -
