Abstract

Field experiments were carried - out at Gemmeiza Agriculture Research Station, during summer seasons of 2014 and 2015. A split - plot design with four replications was used, where nitrogen fertilizer levels (N) (0,45,90 and 135 kg.fad-1) were plotted in main plots and humic acid (HA) (0, 1, 2, and 3kg.fad-1 ) were assigned to sub plots. Increasing nitrogen levels up to 135 kg N.fad-1 .increased all yield and yield components in both seasons. Increasing humic acid levels, recorded highly significant increased for 100 - grain weight (g), grain yield fad-1, biological yield and straw yield in both seasons. While, harvest index had significantly decreased in both seasons, with increases in either nitrogen or humic acid levels. The interaction between nitrogen and humic acid  was  significant  for ear height, 100 -grain weight (gm) and grain yield ard.fad.-1, while, was insignificant for No. of rows ear-1 and No. of grains row-1 in both season. Hence it might be concluded that, 135 kg N + 2 or 3 kg HA.fad.-1, in separate application or in combination led to significant increase in maize grain yield and its components of SC. 131.
