Abstract Japanese mint (Mentha arvensis L.) often suffers from Fe-chlorosis during the regeneration phase after first harvest when grown on alkaline/calcareous soils. Field studies were conducted during 1987 and 1988 seasons on an alkaline sandy loam soil (pH = 8.0; 4.6% CaCO3) to investigate the influence of soil and foliar applied Fe on yield and Fe status of ‘MAS-1’ and ‘Hybrid-77’ Japanese mint. Significant oil yield increases were obtained with two applications of Fe-EDTA, and FeSO4 in mixtures with ammonium sulphate and mint compost (mint distillation waste) and four split applications of FeSO4 (total Fe of 12 kg ha−1) between sprouting and 30 days after first harvest compared to the control. The highest oil yields from two harvests (180 kg ha−1) were consistently obtained with the Fe-EDTA treatment. Soil application of FeSO4 at sprouting and first harvest were ineffective compared to Fe-EDTA application. Foliar application of 30 kg ha−1 of Fe-EDTA resulted in oil yields equal to the yields obtained with soil application of 140 kg ha−1 of Fe-EDTA. Fe applications increased the concentration and the total uptake of Fe by the crop. Foliar application of Fe-EDTA at two weeks interval alleviates Fe-chlorosis in Japanese mint.
