Pengaruh Pupuk Organik dan Pupuk KCl Terhadap Pertumbuhan dan Hasil Ubi Jalar Ungu (Ipomoea batatas Poir)
Abstract: The aimed of
research was studied the effect of application of organik and KCl for growth
and yield of purple sweet potato and get the best treatment combination. This
research has been conducted in the experimental garden of Faculty of
Agriculture, University of Riau, Jalan Bina Widya, Baru Simpang Village,
District Tampan, Pekanbaru.in August 2016 until November 2016. This research
using Factorial Random Design (FRD) Factorial consisting of two factors. The
first factor is the provision of organic fertilizer. cattle manure, forage of
gliricidia sepium, and compost of empty palm oil bunch (OPEBC,) of 10 ton/ha. The
second factor is the dosage of KCl fertilizer consisting of 4 levels: K0:
Without KCl, K1: 50 kg/ha, K2: 100 kg/ha, K3: 150 kg/ha.The research parameters
were stem length, number of primary branch, stem length, tuber diameter, fresh
tuber weight/plant, fresh tuber weight/m2, tuber number/plot and yield index.
The data were analyzed statistically using ANOVA and continued with
Duncansfurther Test at 5% level. The results showed that organic fertilizer and
KCl fertilizer had significant effect on tuber diameter, fresh tuber
weight/plant, fresh tuber weight/m2, tuber number/plot, yield index, and no
significant effect on stem length, number of primer/plant branch and length
tuber, Provision of composted fertilizer OPEBC 10 ton/ha and KCl 100 kg/ha
fertilizer can increase the growth and yield of sweet potato crops.
