EFFECT OF SEAWEED CONCENTRATE ON THE GROWTH OF THE SEEDLINGS OF 3 SPECIES OF EUCALYPTUS

The effect of the seaweed concentrate Kelpak on the growth of seedling s of three species of Eucalyptus was investigated. A preliminary exper iment showed that foliar sprays of Kelpak significantly increased the growth of seedlings of E. nitens and E. macarthurii. The main experime nt was carried out on E. grandis, and studied the best method of apply ing the seaweed concentrate and the best time of application. Results showed that both foliar sprays and root flushes increased root and sho ot growth. For both methods of application, a single dose early in the life of the seedling was optimal. There was little benefit in applyin g Kelpak after transplantation. Results clearly showed that seaweed co ncentrate can improve seedling growth in Eucalyptus species.
