| dc.description.abstract | research entitling “utilization ash bunches empty oil palm as substitute
KCl fertilizer on growth and result waxy corn (Zea mas Certaina) on regosol soil”
was conducted in the Green House, Faculty of Agriculture, Universitas
Muhammadiyah Yogyakarta from December 2018 to March 2019. The research
purpose to determine the effectiveness and to get the exact dose of oil palm empty
fruit bunch ash as a substitute for K fertilizer for the growth and yield of waxy
corn or glutinous corn (Zea mays var. Ceratina). This research was carried out
by the experimental method single factor in polybags arranged in Complete
Random Environmental Design consisting of 5 treatments, namely (P1) 100% K
from KCl fertilizer, (P2) 75% K from KCl + 25% K fertilizer from oil palm empty
fruit bunch ash, (P3) 50% K from KCl + 50% K fertilizer from oil palm empty
fruit bunch ash, (P4) 25% K fromKCl + 75% K fertilizer from oil palm empty fruit
bunch ash, (P5) 100% K from oil palm empty fruit bunch ash. Parameters
observed included plant height, number of leaves, leaf wide, root length, fresh
root weight, dried root weight, fresh plant weight, dried plant weight, cob height,
cob diameter, cob length, number of row for each glob, husked cob weight,
without husk cob weight. The results showed all balance treatment of oil palm
empty bunch ash substitute element K and a balance treatment of 25% K from
KCl + 75% K fertilizer from ATKKS is the right dose, having a globus weight of
231.95 g, higher than other treatment. | en_US |
