Bareroot technology of prickly narra (Pterocarpus vidalianus Rolfe) and large leaf mahogany (Swietenia macrophylla king)
1992
Calora, F.G. Jr.
Mycorrhizae inoculation had a significant (P0.05) effect on the stem diameter of large leaf mahogany and the plant height of prickly narra. The root pruning treatments had significant effect on the plant height, stem diameter, root:shoot ratio, number of roots developing from severed tap root and dry weights of large leaf mahogany while on prickly narra it had a significant effect on the root:shoot ratio, number of roots developing from severed tap root and nodule counts. The best treatment combination selected for the bareroot production of large leaf mahogany and prickly narra were wrenching with Mykovam 1 and wrenching + box pruning with Mykovam 1, respectively. These seedlings were field planted and subjected to different fertilizer treatments. For large leaf mahogany, fertilizer treatment had a significant effect on the height and diameter increment. Height increment were significantly different from Jan-Feb 1991. Diameter increments were also significantly different from Mar-Apr 1991. The height and diameter increment of those fertilized were significantly greater than the control. However, the monthly survival rates of large leaf mahogany were not significantly different from each other. For prickly narra, fertilizer treatments had significant effect on the height increment from Aug-Sep 1990, but did not have significant effect on diameter increment. The monthly survival rates of prickly narra with fertilizer treatments were higher than the control, but were not significantly different from each other.
