Various manganese fertilizers [manganese sulfate (MnSO4·3H2O (MS), 27% manganese (Mn); and Mn-ethylenediaminetetraacetic acid (EDTA) (ME), 12% Mn] and their doses (0, 6, 9, 12 mg Mn kg-1 and 0, 0.2, 0.3, 0.4%) were applied to soil and sprayed on leaves to study the variations in yield and yield components (plant height, number of pod per plant, number of grain per pod, thousand grains weight, and protein) of dwarf bean (Phaseolus vulgaris L. cv. 'Akman-98') grown under Konya (Turkey) ecological conditions during two consecutive growing seasons in 2006 and 2007. Field experiments were conducted in randomized block split plot design with four replications. All soil applications were made on bands as a single application at sowing whereas foliar applications were made in two sprays on the 25th and 35th days after seed emergence. According to the results, foliar application of ME resulted in better yield and yield components than the MS application and all types of soil applications. The highest grain yields were obtained by the 0.2% of ME sprayed on the leaves in the first year (2783.4 kg ha-1) and that of 0.3% of ME also sprayed onto the leaves in the second year (3092.1 kg ha-1).
