The effect of sprout inhibitors, maleic hydrazide (MH), and isopropyl‐N‐(3‐chlorophenyl)‐carbamate (CIPC), on nitiate‐N (NO 3 ‐N) content of tubers was investigated. The effect of rate of application of nitrogen fertilizer and variety on NO 3 ‐N content of tubers was also examined. Foliar application of MH significantly (p < 0.01) increased NO 3 ‐N content of the tubers. NO 3 ‐N content increased significantly (p < 0.01) with increasing amounts of MH application. No significant differences in NO 3 ‐N content of tubers were observed with CIPC treatment. NO 3 ‐N content increased significantly (p < 0.05) in tubers with increasing nitrogen fertilization rates. Varieties differed in their NO 3 ‐N content. The NO 3 ‐N content of the cortex was significantly (p < 0.05) higher than the corresponding pith tissue regardless of treatment.
