Abstract: The research aimed
to study the application of the combination of compost of palm oil empty fruit
bunches (POEFB) with boiler ash and oil palm mill liquid waste (LW) of oil palm
industry to growth and yield of soybean as intercropping in oil palm plantation
that have been produced in the peat land. The research was conducted at oil
palm plantation (6 years old) at Kualu Nenas Village, Kampar Regency, Riau
Province from August to November 2013. The research used Randomize Complete
Block Design (RCBD) consist of seven treatment (A = 1.44 kg compost of POEFB +
144 g boiler ash/plot, B = 1.44 kg compost of POEFB + 288 g boiler ash/plot, C
= 1.44 kg compost of POEFB + 432 g boiler ash/plot, D = 1.44 kg compost of
POEFB + 8.64 ml LW/plot, E = 1.44 kg compost of POEFB + 144 g boiler ash + 8.64
ml LW/plot, F = 1.44 kg compost of POEFB + 288 g boiler ash + 8.64 ml LW/plot
dan G = 1.44 kg compost of POEFB + 432 g boiler ash + 8.64 ml LW/plot) each
treatment repeated three times. Parameters observed were plant height, number
of prymary branches, number of pods, a percentage of pods pithy, flowering age,
dry weight of seed and dry weight of 100 seeds. The result showed that the
application of 1.44 kg compost of POEFB + 288 g boiler ash + 8.64 ml LW/plot
(F) increase plant height, number of pods, a percentage of pods pithy and dry
weight of seed significantly compared with the another treatments, but not
significantly with the application of 1.44 kg compost of POEFB + 432 g boiler
ash + 8.64 ml LW/plot (G)
