In: Journal of the Advances in Agricultural Researches 2006.v.11(1)Summary: Three field experiments were conducted during late summer seasons (nily season) of 2003, 2004 and 2005 at Nubaria Agriculture Research Station, to study the effect of potassium application on grain yield and leaf blight disease severity (Helminthosporium furcicum) of six commercial maize (Zea mays l.) lines. Four rates of potassium fertilizer (zero, 24, 48 and 72 kg K2O fad-1) and six commercial lines (Sd.7, Sd.63, Gz.602, Gz.612, GZ.628 and Gm.2) were tested in this study. Data were recorded for grain yield (ard fad-1), leaf blight disease severity (%), plant height (em) and days to mid-silking (d).
