This study was conducted to examine the nitrogen effects on uptake and utilization of major mineral nutrients of the kidney bean (Phaseolus vulgaris L.). The N treatments were five levels, 0, 3, 6, 9, 12 N kg/10a. The kidney bean was cultivated on the upland experimental field in the agricultural ????
research & extensions service of Chungbuk province. The contents and uptake amounts of mineral nutrients were investigated throughout the growth stages of the kidney bean. Higher content of total N in the stem was maintained until 8 days before flowering stage and then decreased gradually. Also, total N content of leaves was increased in the vegetative growth stage, and it was decreased rapidly to 8 days after the flowering stage, and then increased gradually to the initial maturity stage. Total N content of roots was tended to decrease until 8 days after the flowering stage, while that of seed was increased from the flowering stage to the maturity stage. The amount of uptake N of the shoot parts was increased until the flowering stage, maintained similarly from the flowering to 14 days after the flowering stage, and then increased rapidly to the maturity stage, while that of root was increased slowly to the flowering stage and then maintained similarly to the maturity.
