%X The national average yield of
maize is by far lower than the world average yield. Plant density is one of the
factors that affect yield. Therefore, know</span><span style=\"font-family:Verdana;\">ing the</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">appropriate agronomic practices </span><span style=\"font-family:Verdana;\">are </span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">paramount importance to ma</span><span style=\"font-family:Verdana;\">ximize maize production
in Ethiopia. A field experiment was conducted under rainfed conditions in 2015
and 2016</span></span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">during the main cropping season at </span><span style=\"font-family:Verdana;\">Haramaya</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">to</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">determine the effects of inter and intra row spacing on grow</span><span style=\"font-family:Verdana;\">t</span><span style=\"font-family:Verdana;\">h, </span><span style=\"font-family:Verdana;\">yield
components, and yield of hybrid maize varieties. The experiment consisted of
the factorial combinations of two hybrid maize varieties (</span></span><span style=\"font-family:Verdana;\">¡°</span><span style=\"font-family:Verdana;\">BH-661</span><span style=\"font-family:Verdana;\">¡±</span><span style=\"font-family:Verdana;\"> <span style=\"font-family:Verdana;\">and </span></span><span style=\"font-family:Verdana;\">¡°</span><span style=\"font-family:Verdana;\">BH-QPY-545</span><span style=\"font-family:Verdana;\">¡±</span><span style=\"font-family:Verdana;\">), two inter-row</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">spacing (65 and 75 cm) and three intra-ro</span><span style=\"font-family:Verdana;\">w spacing (25, 30 and 35 cm) in a 3 ¡Á 2 ¡Á 2 factorial in a randomized
