INTRODUCTION
Leucaena lewcocaphela (Lmk. de Wia.) (kernlandingan) is a tree, which has an
bnportmt rob both as forest plant and cultivated crops. In Indonesia, L. lencocephala has
bstn known for along time and is used for intercrops at teak planErrtian or as shade plants
d geegreen m ~ w eprducers in plantation (in Martadid& 1971). This species is also
way useful as plants for erosion prevention (Martadiradja, 1971; Baage, 1976), alangh g eradication (Knoop, 1910; Mathcws, 1974, Benge, 1976) and soil amendsncnts
(Msutadiredja, 1971).
One problem in management of L. leucocephakr crop was difficulty in procurement
of high quality seed in sufficiently amount.
