Abstract

Shallot is the most important horticulture commodity as a cooking spice after chilli. The
purpose of this research wa to know the effect of pomi fertilizer and NPK grower on shallot yield.
The research was conducted at the expremental farm of Facuty of Agriculture Riau Islamic
University Pekanbaru during three months, from December to February 2016. The randomized
completely design with two factors was used. The first factor used pomi fertilizer (0, 5, 10, and 15
cc/l water), while the second factor was NPK grower (0, 10, 20, and 30 gr/plot). Parameters observed
were number of tillers, tuber diameter, wet bulb weight per hill, wet bulb weight per plot, dry bulb
weight per hill and weight of dried tuber per plot. The results showed that interaction had an effect on
all observation parameters with best treatment of P2N3 (10 cc/l water of pomi fertilizer and NPK
grower 30 g/plot). Mainly, fertilizer application gave an effect on all observation parameters with
best treatment of P2 (10 cc / l water), whereas NPK grower application gave an effect on tuber
diameter, wet bulb weight per hill, wet tuber weight per plot, tuber weight dry per hill and weight of
dry bulb per plot with best treatment N3 (30 g/plot).
