Abstract: | A corn cultivar × P × K factorial experiment was conducted to evaluate differential responses of selected parameters to P and K soil fertility. Yield along with leaf nutrient concentration of some nutrients differed among cultivars and nutrient concentration of some elements was affected by soil fertility. Leaf K and Mg were more consistently affected by K fertility than other variables studied. Fertility effects upon micronutrient leaf concentration were not consistent among cultivars or between years. |
