Pertumbuhan Bibit Kelapa Sawit (Elaeis Guineensis Jacq) Pada Kondisi Hipoksia Yang Diberi Pupuk Daun Dan Zat Pengatur Tumbuh
ABSTRACT
The aims of this research is to improve the growth of seedlings of oil palm
plant (Elaeis guineensis Jacq.) seedlings under hypoxia conditions by applying
foliar fertilizers with growth regulators. This research was conducted at
experimental field of the Faculty of Agriculture, Universitas Riau from July to
November 2019. The study was conducted with a split plot design in simple
pattern in three replication. The main plots were foliar fertilizer (D), consisting of:
d1 = organic liquid foliar fertilizer, d2 = inorganic solid foliar fertilizer, and d3 =
inorganic liquid foliar fertilizer, and subplots were the growth regulators kind (Z),
which consisted z1 = auxin, z2 = cytokinin, and z3 = gibberellins. The variable
observed were: seedling height, number of leaf midribs, tuber diameter, root shoot
ratio, seedling dry weight, and seed quality index. The data analyzed of variance,
and continued by orthogonal contrast test at 5%. The results showed, no
interaction between foliar fertilizers and growth regulators on all growth
components of oil palm seedling in hypoxia, but foliar fertilizer affects to the dry
weight of the seeds and the seed quality index, which the inorganic foliar fertilizer
does increased the seedling dry weight, and seedling quality index.
