SKRIPSI PENGARUH DAN DOSIS WAKTU APLIKASI PUPUK UREA BRIKET TERHADAP HASIL KUBIS BUNGA HIJAU (Brasicca oleracea var. botrytis L. subvar. cymosa Lam. )
ABSTRACT
The research concering "The effect of doses and the
time of application ures brick fertilizer to the yield of
broccoli "had been conducted in Gogik village, Ngablak,
Magelang, central Java from September, 16th to November,
8th, 1993 with Regosol soil type and the altitude of meters a bove of sea levels. 1350
meters a bove of sea levels.
The research has used factorial experiment method
with basic design Randomized Completely Block (RCB) there
are consisted two factors and three time replication.
First factor : Fertilizer dose (D), consisted three
levels
D1 :120 kg urea/ha dose (3 g urea/plant)
D2 :200 kg urea/ha dose (5 g urea/plant)
D3 : 280 kg urea/ha dose (7 g ures/plant)
Second factor : Application time (W), cor.sisted of three
levels:
WI :Urea brick manuring on moment planting
W2 : Urea brick manuring on 4 days after
planting
W3 :Urea brick manuring on planting 8 days after
The result of this research showed:
1. The urea brick fertilizer dose were significantly
different on the diameter of curd, weight of curd per
plant and dry weight of straw. On the height of plant,
number of leaves, weight of curd per plot, fresh weight
of straw, age of flowering, harvest age and harvest
index were not significantly different.
2. The manuring application time was not significantly
different on all the parameters were observed, except
the number of leaves.
3. The interaction between the urea brick fertilizer dose
and the manuring application time was not significantly
different on all the parameters were observed, so that
urea brick fertilizer dose and manuring application
time can used separatly.
