ABSTRACT
"Materia Medica", Tbchnical Implementation Unit, East
Iava Health Service Bureau, Batu, East Java, ftom May to December 1995. It has an
altitude of approximatety 750 m above sea tevet. This study has the objective of detetqualmtning lighi intensity and fruit thinning which maximize strawbeny yield of high
The study was done
in

three replicate two factors experiment, laid out in a completely randomized
design with repeited measufements were. The first factor was shading intensity consisb
was

The results indicated that : (1) maximum grawth and yield of strawbery was at'
