EFFECTS OF TIMING AND NITROGEN FERTILIZER APPLICATION RATES ON MAIZE YIELD COMPONENTS AND YIELD IN EASTERN ETHIOPIA

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

Noble-Metal Chalcogenide Nanotubes

We explore the stability and the electronic properties of hypothetical noble-metal chalcogenide nanotubes PtS2, PtSe2, PdS2 and PdSe2 by means of density functional theory calculations.Our findings show that the strain IMPATIENS energy decreases inverse quadratically with the tube diameter, as is typical for other nanotubes.Moreover, the strain ene
