Abstract
In order to investigate the relation between mineral nutrition and nitrogen metabolism, ash analysis of above mentioned samples was fully made.By the dressing of nitrogen the content of nitrogenous matter and carbohydrates fluctuate severely but affect slightly to those of mineral matter.Top dressing of nitrogen causes the increase of total ash absorbed, which indicates vigorous activity of absorbing power. Among the elements absorbed, largest part of nitrogen and phosphorus moved to ears from leaves, some part of potassium, magnesium, manganese and sulphur. But as to silicon, calcium and iron almost all part absorved, rematinedin the leaves and sheaths.
