Abstract: This research aims
to determine the effect of N, P and K on the growth and yield of Bima Brebes
and Thailand varieties onion and the best dosage to support in ultisol soil.
This research has been conducted in the field of Agricultural Extension Center,

fertilizer, N, P, and K comprising 4 levels, namely: urea 250+ TSP 150 + KCl
100 kg/ ha, urea 500 + TSP 300 + KCl 200 kg/ha, urea 750 + TSP 450 + KCl 300 kg/ha dan urea 100 + TSP
600 + KCl 400 kg/ha. Parameters measured were dry weight, weight of tuber per
hill, tuber number, tuber wrap, fresh tuber weight per plot and the weight of
feaseable storage of tuber per plot. The result showed that the Thailand
varieties of urea fertilizer and 1000 kg/ha + TSP 600 kg/ha + KCl 400 kg/ha
