| description | Three approaches were employed to study some nutritional
aspects of Pinus caribaea var. hondurensis namely, soil
analysis, soil bio-assay and foliar analysis.
Five soil composites each from Kemasul (Pahang) and ulu
Sedili (Johore) plantation areas were analysed for physic al
and chemical properties. For pot culture, a 2²x 6 factorial
experiment using soil collected from Kemasul was conducted to
study the effects of nitrogen, phosphorus and potassium on the
growth of p. caribaea var. hondurensis seedlings. Nitrogen and
potassium were applied at levels equivalent to 0 and 112 kg/ha;
and phosphorus at 0, 168 kg/ha, 336.2 kg/ha, 504 kg/ha,
672.2 kg/ha and 840.3 kg/ha. At the end of the experiment, dry
weight of roots, stems and needle s were determined. Needles
were analysed for N, P and K contents. Simultaneously, two
randomised complete block fertiliser trials were laid out in the
field. Nitrogen and potassium were applied at 0 and 224 kg/ha each
while phosphorus was given at 0, 336.2 kg/ha, 672.2 kg/ha and
1008.3 kg/ha levels. Needles from these plants were collected at
three times to concide with dry (February - May), transitional
(June - september) and wet (October - January) seasons from five
positions in the crown.
The study shows that phosphorus is highly deficient at both
the sites. Application of p.fertiliser at the rate of about
340 kg/ha at Ulu Sedili and about 504 kg/ha at Kemasul would be desirable for optimum gorwth of P. caribaea var. hondurensis seedlings. |
