Abstract: Shorealeprosula
included major timber producing tree and widely used include the use of such,
plywood, sawn timber, and buildings of
contruction.Shorealeprosulaproductiondecreasedamount, becausemost of the
production comes fromnatural forests. The cultivation needed so shorealeprosula
not become extinct, for it is important in the provision of quality seedlings.
Shorealeprosula includedsemi tolerant types that require low light intensity
for early growth. The nursery needed microclimate modification that environment
conditionaccording to the requirement growing seedlings
shorealeprosula.Alternativemade is bygivingshadeinthe nurseryShorealeprosula.
This research aimstodetermine the effect ofshadeon the successandthe intensity
ofthe shadeis best, on the growth ofseedlingsShorealeprosula the medium topsoil
and compost mixture ratio 1:1.This research uses a completely randomize design
method which consist of 5 treatments, 3 replications, and 5 units of the plant
as a research unit.P0 = Without giving shade; P1 = the provision of shade level
of 45%; P2 = the provision of shade level of 60%; P3 = the provision of shade
level of 90%. The result indicates that treatment giving shade level of 90% is
the best treatment on the parameters of observation, the high increasing (2,24
cm), the diameter increasing (1,2 mm) for seedlings Shorealeprosula in medium
topsoil and compost mixture ratio 1:1.
