| Summary: | ABSTRACT
This objectives of this research were to observe the effect of light intensity, mulching by using alang-alang and phosphat fertilizer to the growth and mycorrhiza formation of Shorea academia in the field.
High light intensity had better effect in term of height parameter however low light intensity had better effect also in term of diameter growth, number of leaves and percent of mycorrhiza. Low light intensity affect better to the structure of soil and more activity of microorganism in the soil and could reduce the alang-alang competition to S. academia growth.
Alang-slang is not appropriate for mulching material of S. academia. There is no effect of posfat fertilizer to the height, diameter number of leaves and also percent of mycorrhiza in Bukit Suharto due to the very acidic soil so make bigger possibility P
fixation of soil. |
