Summary The physical lengths, dry matter distribution among the parts of phyto-mers and diameter of internodes of Java variety were compared. The leaf blade was 18–20 times longer and the sheath length 2–6 times than the respective intemode (s) in the main shoot which amounts to greater drain of biological energy. The lengths of peduncle and panicle formed 50% of the total height. The translocation of the assimilates take a long course to reach panicle as they pass through sheaths and stem from the blades. Appropriate dimensions were projected to avoid imbalanced organ growth, energy drain and to strengthen stem and shorten the route of assimilates.
