Abstract This study aimed to determine the optimal maize NPK microdosing rate in Mali and compare labor requirements for mechanized versus manual sowing and fertilization across three locations with varying rainfall. The treatments included six microdosing rates, ranging from zero to 93 kg NPK/ha (3 g NPK/hill), and the recommended rate of 100 kg NPK/ha applied by row application. All...

The objective of this study was to characterize pearl millet production in Niger and to assess the potential impact of a low-cost production package on land- and labor productivity. The survey showed that 62% of the farmers used manure, while 22% used mineral fertilizer. Of those who used mineral fertilizer only 18% practiced microdosing. High labor demand was given as the reason why 89% of the...

Pearl millet production in Niger is characterized by manual sowing and weeding and low use of inputs like mineral and organic fertilizer. This objective of the study was to compare a traditional production package (control) against a new production package consisting of mechanized sowing and weeding, seed priming, seed treatment with a fungicide/insecticide, and microdosing at rate of 0.3 g NPK...

Sorghum and pearl millet are the most important stable crops in the drylands of West Africa. This four-year study based on two experiments assessed different low-cost methods for intensification of sorghum and millet production under contrasting rainfall conditions in Mali. Experiment 1 assessed the microdosing rates 0, 0.2, 0.4, 0.6 and 0.8 g NPK hill−1 combined with seed priming across four...

SUMMARY: Intensification of maize production is imperative to improve food security for the rising population in the central rift valley (CRV) of Ethiopia, whose livelihood is principally based on rainfed maize that operates under shrinking landholding and high seasonal rainfall variability. This study examined different levels of intensification options in maize production by sequentially...
