Impact of shade on morpho-physiological characteristics of coffee plants, their pests and diseases: A review

Traditionally coffee plant has been considered as a shade demanding species and intolerant of direct sunlight, although it performs well without shade. Still it has been controversy result and recommendation among investigators in the optimal shading level for coffee growth. This controversy will probably continue endlessly until we know better the effects of shade up on the performance of morphology and physiology of the...

Agronomic efficiency of phosphorus, growth characteristics and yield of maize as affected by inorganic fertilizer and tithonia biomass application

Low soil nitrogen and phosphorous levels are among several constraints limiting crop productivity in southwestern Ethiopia. The dominant soil types in the region are acidic nitosols that are often low in plant available phosphorus. Most farmers cultivate maize with minimal external inputs, hence resulting in sub-optimal yield levels. The effect of applying tithonia biomass and phosphorus fertilizer on agronomic efficiency...
