Effect of weeding and some soil characteristics on the survival and growth of Pinus caribaea in plantations at Ruvu



Effect of weeding and some soil characteristics on the survival and growth of Pinus caribaea in plantations at Ruvu



Record, Division of Forestry, University of Dar es Salaam (8): 12



Survival was determined by systematic sampling in 1- to 9-yr-old plantations and field experimental trials of P. caribaea with different weeding histories. Ht. was measured for 1- and 2-yr-old pines. The results suggested that survival depended largely on intensive weeding. Only in those plantations that received 6 weedings in the first 2 yr did survival exceed 80%. Weed competition did not significantly retard growth in either 1- or 2-yr-old plantations.
