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...
