Abstract
The objective of this study was to determine the grain and stover yield response of pearl millet to microdose fertilizer application alone, and microdose combined with N and P fertilizer application rates across years and locations in West Africa. Microdose fertilizer application increased pearl millet grain yields by 240 to 300 kg ha-1 on sandy soils across a broad range of climatic and soil conditions in West Africa, while increasing pearl millet grain yields by 400 kg ha-1 on silty clay soils in Mali. Stover yield increases of pearl millet were 250 to 400 kg ha-1 on sandy soils and 500 to 2500 kg ha-1 on silty clay soils in Mali. Application of 20 kg ha-1 P2O 5 and 30 kg ha-1 N in addition to microdose commonly increased grain yields by 140 to 180 kg ha-1 and stover yields by 600 to 1500 kg ha-1 over that of microdose application only. These results indicate that micodose in combination with 20 kg ha-1 P2O5 and 30 kg ha-1 N fertilizer application is required to optimize both grain and stover yield of pearl millet in West Africa to meet food, fuel and soil improvement needs of farmers.
