J. Vanstaden et al., EFFECT OF SEAWEED CONCENTRATE ON THE GROWTH OF THE SEEDLINGS OF 3 SPECIES OF EUCALYPTUS, South African journal of botany, 61(4), 1995, pp. 169-172
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.
