Having highest HA recovery (20%) black coal derived HA were applied in different level [(@ no HA (HA0), 25 (HA1) and 50 (HA2) mg kg<sup>-1<\/sup>&nbsp;soil)] in conjoint with different nitrogen (N) levels [no N application (N0) (150 (N<sub>1<\/sub>) and 300 (N<sub>2<\/sub>) mg kg<sup>-1<\/sup>&nbsp;]. Results showed that plant fresh biomass increased by 23% and 44% with application of HA at HA<sub>1<\/sub>&nbsp;and HA<sub>2<\/sub>&nbsp;respectively, about 23% increase was observed in dry plant biomass at both the HA levels. Cob weight and grain weight increased significantly (29% and 40%) with HA at 25 and 50 mg kg<sup>-1<\/sup>&nbsp;respectively vis as vis control (no HA applied), with N at 150 and 300 mg kg<sup>-1<\/sup>&nbsp;the increase was 51% and 103%. The grain weight increased by 12% and 41% with HA<sub>1<\/sub>&nbsp;and HA<sub>2<\/sub>&nbsp;whereas, 31 % and 43 % with N application (N<sub>1<\/sub>&nbsp;and N<sub>2<\/sub>&nbsp;over the control). The HA application increased plant N contents by 20% and 26 %, P by 14% and 20% and K by 15% and 10% in HA1 and in HA<sub>2<\/sub>, respectively. Nutrient uptake also enhanced with both N and HA application. From the results it can be concluded that HA application along with N help improved growth, yield and nutrient uptake by maize.<\/p>\n<\/div>\n<div class=\"item abstract\">\n<div>\n<h3 class=\"label\">How to Cite this paper?<\/h3>\n<div class=\"csl-entry\">\n<p><strong>APA-7 Style<\/strong><br>Khan, M.Z., Akhtar, M.E., Ahmad, S., Khan, A., Khan, R.U.
