Abstract :
Ratoon is a rice cultivation that is carried out by maintaining rice shoots that grow
after harvest. Ratoon rice has several advantages, that are faster harvest and lower
production costs than the parent plant. However, ratoon has a drawback, namely the
level of production is still low. Therefore in this study using superphosphate and
biofertilizer to increase production. Phosphorus is expected to increase the rate of
growth and formation of rice grains. This research was conducted from April to July
2020 in Tegalgede Jember. This study was designed using a two factorial split plot
design with 4 replications. He first factor being superphosphate fertilizer and the
second factor being biofertilizer. The first factor consisted of 3 levels, namely 50
kg/ha-1
, 75 kg/ha-1 and 100 kg/ha-1
, while the second factor consist of 3 levels, namely
30 g/ha-1
, 60 g/ha-1 and 90 g/ha-1
. The variables observed consist of plant height,
number of tillers, number of productive tillers, number of grain per panicle, number
of empty panicles, number of panicle grain, leaf area, number of leaves, panicle
length and chlorophyll. Observational data were analyzed using ANOVA if the results
showed significantly different or very significant differences, then further tested using
DMRT 5%. The results of this study showed that 50 kg/ha-1
superphosphate
fertilization and 60 g/ha-1 biofertilizer gave the best effect on the number of
productive tillers (24.18 stems), while 50 kg/ha-1
superphosphate fertilization gave
the best effect on the number of productive tillers. pithy grain per panicle that is (69.4
grains).
