To suggest the adaptive zones of malting barley, fifteen places were selected by their average temperature during the cropping period. Climatic variables, soil properties of the regions were investigated as well as growth, yield and quality of crops collected from farm fields. Selected areas were classified by daily minimum temperature averaged over January into 3 broad zones as Zone Ⅰ (above -2℃) Zone Ⅱ (between -2 and -3℃) and Zone Ⅲ (between -3 and -4℃). There were clear regional differences in soil properties and crop characteristics investigated. Zone Ⅰ and Ⅱ were considered as the adaptive zones for malting barley cropping. Majority of soils in Zone Ⅰ were local alluvial soil, fluviomarine soil, old alluvium soil and alluvial plain soil, whilest soils of Zone Ⅱ and Ⅲ were local alluvial soil, granite and granite-gneiss residual soil. Chemical analysis of soils showed that Zone Ⅰ has higher contents of NH₄-N, organic matter and soluble Boron, whereas Zone Ⅱ has higher NH₄-N, Ca, Mg, K and Fe. On the other hand, Zone Ⅲ showed lower contents in all investigated soil components except CEC, Ca and P₂O₅. Chemical analysis of plant material sampled at the times of effective tiller termination and yellow ripening stage showed that far southern regions produced crops of lower contents of T-N, P₂O₅, SiO₂, Fe and Mn, indicating a faster translocation of these nutrients to the ears. Crops produced in Zone Ⅰ had a smaller cuim length and a shorter duration of growth for heading and maturity, but they produced bigger numbers of ears and higher grain yields. Grain per ear and 1000 grain weight were smaller compared with other regions. Zone Ⅰ and Zone Ⅱ were again considered as adaptive regions for proper growth and yield of malting barley. Zone Ⅰ and Ⅱ produced better crops of malting quality compared to Zone Ⅲ as germination energy, germination rate, solube N, Kolbach. index, saccharification time and diastatic power were higher in Zone Ⅰ and soluble N, saccharification time and Kolbach index were higher in Zone Ⅱ. The adaptive regions of malting barley were south of a line connecting Muan, Yeongam, Jangheung, Bosung, Seungju and Kwangyang in Jonnam province and Hadong, Southern parts of Sanchung, Eureong, Haman, Milyang, Kimhae in Gyeongnam province. These regions were considered as advantageous in both yield and quality.
