SKRIPSI PENGARUH SAAT PEMUPUKAN UREA BRIKET DOSIS 187,5 KG/HA TERHADAP PRODUKSI TIGA VARIETAS PADI (Oryza sativa L.)
ABSTRACT
The experiment about the effect of fertilizers time
of ure briket dose 187,5 kg/ha for three rice varietas
productive, had been carried act since November 24, 1993
until March 30, 1994. the location of the experiment was
at Kroyokulon Village, sub District North Kemiri, Purwo-
rejo City, Central Jawa. The soil type is latosol with pH
6.1, by technis irigation and on an altitude of 20 meters
above sea leval.
The experiment used factorial methode with arranged
by Split Plot Design, pondation arranged Randomized
Completely Block Design (RCBD) using 2 factor and 4
replications.
The first factor, sort varietas (V) were: varietas Cisa-
dane (V1), IR 64 (V2), Ciliwung (V3).
The secon factor, fertilizers time (P) were: in give one
fold to plant time 0.15 kg/partition (P1), in give there
fold 0,05 kg/partition to plant time, 0,05 kg/partition
20 age, 0,05 kg/partition 40 age (P2) and in give two
fold 0,1 kg/partition to plant time, 0,05 kg/partition 40
age days (P3).
The result of the experiment showed that treatment
of fertilizert time non significant different to all
observation, except to the effect number of tiller stems
50 and 80 age days by significant. The sort of varietas
very significant for height of plant, number of branch
oper strow and significant for namber of rice per strow,
number of full rice per strow, weight of 1000 rice grain,
weight rice of each compartment, and non significant for
number of productive tiller stems. The interaction be-
tween sort varietas and the fertilizert time urea briket
non significant parameters.
