Abstract
A greenhouse investigation was conducted to determine the effect of arbuscular mycorrhiza, N. P. K fertilizer and moisture supply on Mansonia altissima seedlings. The experiment was 3x3x3 factorial experiment in completely randomized design with each of factor has 3 levels and was replicated 5 times. Application of arbscular mycorriza does not have significant effect on growth parameters assessed, while N. P. K fertilizer and moisture supply had significant differences at (p<0.05) on seedling height, collar diameter and leaf production. Seedlings treated to 1 g of fertilizer had the highest seedlings height mean value of 17.34 cm, collar diameter of 3.63 mm and leaf count of 8 while control had the least value of seedlings height, collar diameter and leaf production with 14.80 cm, 3.02 mm and 7 leaves respectively. Seedlings watered at pot capacity on daily basis had the highest seedling height and collar diameter of 16.99 cm and 3.52 mm respectively. Growth responses observed in the present investigation revealed that more research work can be carried out to ascertain the appropriate arbuscular mycorrhiza to be used on the species based on compatibility.
