CAMPURAN KOMPOS TANDAN KOSONG KELAPA SAWIT DENGAN KOMPOS LCC DAN PUPUK FOSFOR TERHADAP PERTUMBUHAN DAN HASIL SORGUM (Sorghum bicolor (L.))
Abstract: This research is
aimed to determine the effect of oil palm empty fruit bunches compost mixed
with leguminosa cover crop compost and phosphorus fertilizers at some
compositions and to get the best mixed toward growth and result of sorghum. This
research was conducted at the experiment land of Agriculture Faculty of Riau
University, Pekanbaru, from December 2013 to April 2014. This research used
factorial completely randomized design (CRD) consisted of two factors and three
replications. As for the treatment is: factor 1 is oil palm empty fruit bunches
compost mixed with leguminosa cover crop compost (K) consist of four level, K1=
5 ton/ha oil palm empty fruit bunches compost, K2= 3,75 ton/ha oil palm empty
fruit bunches compost + 1,25 ton/ha leguminosa cover crop compost, K3= 2,5
ton/ha oil palm empty fruit bunches compost + 2,5 ton/ha leguminosa cover crop
compost, K4= 1,25 ton/ha oil palm empty fruit bunches compost + 3,75 ton/ha
leguminosa cover crop compost. Factor 2 is phosphorus fertilizers (P) consist
of three level, P0= without TSP, P1= 30 kg/ha TSP, P2= 60 kg/ha TSP. The
results of this research showed that 1,25 ton/ha oil palm empty fruit bunches
compost mixed with 3,75 ton/ha leguminosa cover crop compost and 60 kg/ha
phosphorus fertilizers provide the best results for 245,20 g/m2(2,45 ton/ha)
increased by 18,27% compared without P and is significant for the parameters of
plant height, dry weight of plants, result per m2 and sorghum biomass.
