Abstract
ABSTRACTThe effect of sprout inhibitors, maleic hydrazide (MH), and isopropyl‐N‐(3‐chlorophenyl)‐carbamate (CIPC), on nitiate‐N (NO3‐N) content of tubers was investigated. The effect of rate of application of nitrogen fertilizer and variety on NO3‐N content of tubers was also examined. Foliar application of MH significantly (p < 0.01) increased NO3‐N content of the tubers. NO3‐N content increased significantly (p < 0.01) with increasing amounts of MH application. No significant differences in NO3‐N content of tubers were observed with CIPC treatment. NO3‐N content increased significantly (p < 0.05) in tubers with increasing nitrogen fertilization rates. Varieties differed in their NO3‐N content. The NO3‐N content of the cortex was significantly (p < 0.05) higher than the corresponding pith tissue regardless of treatment.
