1. Sensor Based In-Season Nitrogen Determination for Quality Protein Maize on Farmers Field Western Ethiopia

Quality protein maize production is a current common practice and widely produced in western Ethiopia but its productivity is negatively affected by low rate and time of nitrogen application but there is still inadequate research on this phenomenon in quality protein maize production. This in view different attempts have been made to solve the soil fertility problems using sensor-based nitrogen management in southwestern and western Ethiopia. The objectives of this review were to summarize past... T. Abera
