The effect of S fertilization on S and N status and petiole NO3--N in cotton was observed during the growing seasons of 1980 and 1981. Four sites representing 2 soil subgroups were studied using a randomized complete block design with 4 replications. Leaf and petiole sampling began one week prior to bloom initiation and continued weekly for eight weeks. Leaf samples were analyzed for S and N and the petioles for NO3--N. Levels of leaf-S varied directly with amounts of applied S. Leaf-N and petiole NO3--N varied directly with amounts of applied N. Though not always significant, petiole NO3--N and leaf-N showed negative correlations with leaf-S. These results suggest that knowledge of the cotton plant S status may be necessary to interpret petiole NO3--N for N fertilization of cotton. |
