SKRIPSI KAJIAN MACAM PUPUK N ANORGANIK DAN MACAM PUPUK ORGANIK TERHADAP HASIL BROKOLI ( Brasicca oleracea L. var. Botrytis L. subvar. cymosa Lam. )
ABSTRACT
The research about "The kind of N anorganic and
organic fertilizer of Brocoli" had been carried out
since Juli 1 until Oktober 1993 at Wonosobo, Central
Java, on the altitude 800 m above sea level, the
soil type is latosol and pH 6,5.
The research design used Split Plot Design by
Randomized Completely Block Design (RCBD) using two
treatment and three replication.
The first treatment of the kind of N anorganic tilizers (N) were: fer-
tilizers (N) were:
N 1 = anorganic fertilizer of urea
N2 = anorganic fertilizer of ZA
The second treatment of the kind of organic fertili
zer (K) were:
K1 = organic fertilizer of goat
K2 = organic fertilizer of cow
K3 = organic fertilizer of hen
K4 = Azola as the fresh
K5 = Arachis hypogaea L. as the fresh crown
The result of the research showed that N anorga-
nic fertilizer (N) significant different for fresh
weight of crown and not significant different for
height of plant, age of flowering, age harvest, the
net weight of curd per plant, diameter of curd and the
harvest index. The organic fertilizer (K) highly sig-
nificant different for height of plant, the net weight
of curd per plant, fresh weight of crown, diameter of
curd and harvest index, but not significant different
for age of flowering and age harvest, the treatment
of N anorganic fertilizer (N) and the organic ferti-
lizer (K) is created interaction for the net weight
of curd per plant.
The best combination of treatment N2K3 (the
treatment of N anorganic fertilizer of ZA and the
treatment of organic fertilizer of hen), the highest
produce by combination of treatment N2K3 is 196,78 gr
per plant, and the lowest produce by combination of
treatment N2K4 is 130,33 gram per plant.
