Abstract
1) In this study Change of nutrients absorption and the contents in jute plant during the process of growth were investigated.
2) Total dry weight of plant increased through the course of growth, but the tendency of increase in each part of plant was different. Total dry weight continued to increase during the course of plant growth in every part except leaves, in which it did till the early capsule stage and afterwards tended to decrease reversely by degrees.
And so this tendency in both parts of pith with xylem and capsule was particularly distinct.
3) In dry weight, change in rates of each part to the whole plant body was relatively in fiber and non-fibrous part in skin. That in leaves decreased as plant grew, while that in pith with xylem part and capsule part increased.
4) Contents of N, P2O5 and K2O in each part of plant body continued to decrease by degrees through the course of growth, and in these tendencies some differences were recognized among the parts of plant body and also the kinds of nutrients
5) Quantities of N and P2O5 absorbed increased continuously till the seed maturation stage, on the other hand in case of K2O it continued to increase till immediately before the seed maturation stage and afterwards decreased more or less.
6) The nutrient absorption during the process of growth was most vigorous for the period from flowerbud-bearing stage to beginning stage of blooming.
7) As regards the rates of N, P2O5 and K2O contained in each part of plant to those contained in whole plant body the rate of that in leaves decreased by degrees, in case of capsule however, it increased during the growth period.
Those in both parts of skin and pith with xylem changed slightly through the cousse of growth.
