Abstract
The purpose of this research activity was to determine the influence of advance in maturity and level of nitrogen fertilization on the accumulation of nitrogenous materials in the above-ground and below-ground portions of Sorghum vulgar var. Sudanese.
Successive sampling from the 5th to 16th week after emergence revealed a general decrease in the nitrogen concentration of the above-ground and below-ground plant parts. Nitrogen accumulation increased from the 5th to the 12th week for above-ground part and from the 5th to the 13th week for below-ground parts. In both instances, a decrease followed the maximum accumulation. No evidence of translocation from the shoots to the roots was observed. This is in contrast to the physiological activity generally recognized in perennial plants.
