PENGARUH KOMPOS TKKS DAN ABU BOILER KELAPA SAWIT TERHADAP PERTUMBUHAN DAN PRODUKSI TANAMAN BAWANG MERAH (Allium ascalonicum L.)
Abstract: The objective of
this research was to study the interaction of oil palm empty fruit bunches compost and boiler ash , and to
determine the appropriate dosage
combination forthe growth and yield of onion. The research was conducted in
experimental garden of Agricalture faculty University of Riau, Pekanbaru. It
lasted from December 2014 until March 2015.
The research was done in a Completely Randomized Design with two factors
and was replicated three times. The first factor is the compost of oil palm
empty fruit bunches consist of four levels. That is without compost of oil palm empty fruit bunches, 0,3
ton/ha, 0,6 ton/ha, 0,9 ton/ha and 1,2 ton/ha. The second factor is the boiler
ash consist of three levels, that is 50 kg/ha, 100 kg/ha and 150 kg/ha.Data
analyzedby ANOVAandfurthertestedusing byDuncan`sNewMultiple RangeTest(DNMRT)
atthe level of 5%.
The result showed the application of combination oil palm empty bunch
compost with boiler ash increased the plant hight,number of tubers, diameter of
tubers, weight shelf tuber and fresh weight of onion's tuber. The application
oil palm empty bunch compost 0,6-1,2 ton/ha not allowed with application of
boiler ash, and on the application of boiler ash 50-1,2 kg/ha without
application of oil palm empty bunch compot
has showed the highest yield, while the appication of oil palm empty
bunch compost 0,3-1,2 ton/ha with boiler ash 50-150 kg/ha also showed the best
yield.
