Abstract:
This research paper aims at studying the behavior of Prioria balsamiferum saved in layons in this paper is not
only our deepened knowledge contribution in the behavior of Prioria balsamiferum in plantations, but it deals
with data to compare further researches. Our research in plantations lying on Layons method, consisting of
sowing in parallel and equidistant layons ways. Then, we introduce through regular intervals young plants
from farmland in them.
The total inventory realized and trunks of Prioria balsamiferum saved in parcel E-2A remain the main issue
of our research.
The approaches used are:
The breast height diameter (BHD)
The end of barrel height diameter (EBDH)
The crown diameter (CD)
The total height
The barrel height
The houppier height and the average annual rate of growth are parameters which are taken in to
account when analyzing.
After analyzing many cases of Prioria balsamiferum which is 71 years old, the following results are observed:
The rate of Prioria balsamiferum's life is 51,54
The annual average rate of growth in breast height diameter is 0,57 Cm per year
The annual average rate of growth in total height is 0,31 m per year
The annual average rate of growth in barrel height is 0,14 m per year
The average rate of growth in volume barrel is 0,13 m3 per year
The ground surface is 28,23 m2/ha
The average coefficient of form is 0,62
The volume barrel is 171,181 m3/ha
The volume's power from entry is V 0,00070BHD2.495
As conclusion according to what is said above:
The Prioria balsamiferum saved in layons through plantations behave badly in Yangambi area.
The lack of financial possibilities to entertain plantation and the carelessness of the latter are two main
causes of this failure.
Thus, they recommend taking precautions before initiate any project mainly in sowing seeds for a good crop |
