PENGARUH KOMPOS TANDAN KOSONG KELAPA SAWIT (TKKS) DENGAN PUPUK KCL TERHADAP PERTUMBUHAN DAN HASIL TANAMAN BAWANG MERAH (Allium ascalonicum L.) PADA MEDIUM GAMBUT
Abstract: Onion production
which decreased in Riau province affected by the lack of interest and
experience of farmers. Riau has extensive peatlands, efforts to increase the
productivity of peat soil as crop production land can be done by combining the
use of organic such as compost oil palm empty fruit bunches (EFB) and inorganic
fertilizers such as manure KCl. This study aimed to determine the effect of the
combination of composted manure TKKS with KCl and get a dose of compost TKKS
combination with best KCl fertilizer which can improve the growth and yield of
onion on the peat medium. The research was conducted in the House Kasa, the
Experimental Farm of Agriculture Faculty, University of Riau, in November 2015
until February 2016. The research was conducted experimentall using on
completely randomized design (CDR) with 4 treatments and 5 replications. The
data were analyzed statistically by analysis of variance and tested further
with Duncan's multiple range test at 5% level. The results showed that the
administration of various doses of compost TKKS with KCl fertilizer can not
increase the plant height parameters, number of tuber per hill and the
circumference of the tuber however the good effects toward the tuber weight
fresh and the tuber shelf weight per clump on onion crop. Giving compost TKKS
with fertilizer KCl at a dose of 150 kg K2O / ha showed the best results
because it can increase the tuber weight fresh and the tuber shelf weight per
clump.
