Results showed that
N application resulted in significantly (p=0.05) higher grain yield at 80kg N ha-1 in 2010 than that obtained at
120 kg Nha-1 in 2009. Yield in 2010 outstripped yield in 2009 by 23.65%. Results also showed that lime at 500
kg ha-1 gave the highest popcorn yields in 2010, a yield increase of 18.03 % above control, whereas there was no
yield response to lime in 2009
