PENGARUH PUPUK DAUN DAN NAUNGAN TERHADAP PERTUMBUHAN BIBIT GAHARU Gyrinops verstegii (Gilg) Domke DI BAWAH CEKAMAN AIR.
Abstract
ABSTRAK
This research aims to know the influence of leaf fertilizers and shade on the growth of
Gyrinops verstegii (Gilg) Domke under water stress. This research was conducted in the green
house of Faculty of Agriculture, University of Sam Ratulangi Manado, from June to August
2013. Spit plot design is used in this research. Shade as main plot consists of two levels,
namely: 1 layer of paranet N1 (light intensity ± 40%) and 2 layers of paranet N2 (light
intensity ± 16%). Doses of fertilizer as sub-plot consists of 3 levels: P0 as a control (no
fertilizer), P1 0.012 g/plant and P2 0.024 g/plant. The fertilizer was given every week for 2
months. The effects of both shading and fertilizer treatments were not significant on plant
height and stem diameter under water stress.
Keywords: Gyrinops verstegii, water stress.
