Effects of timing and nitrogen fertilizer application rates on maize yield components and yield in eastern Ethiopia
Abstract Maize (Zea mays L.) is an important food security crop in Ethiopia.However, low soil fertility and the use of haphazard nitrogen (N) fertilizer with little attention to the rate and timing of N application constrain productivity.Therefore, field experiments were conducted during the 2019 and 2020 cropping seasons to investigate the respons
