Abstrak

This study aims to determine the effectivity of organic fertilizer and kalium chloride on the growth of union (Allium ascalonium L), to determine the ratio of doses of organic fertilizer and Kalium chloride to union (Allium ascalonium L) and. This research was carried out i UPT Balai Benih Induk Hortikultura KutaGadung Berastagi, at an altitude of + 1,500 m above sea level. This study used a factorial randomized block design (RAK) method consisting of two (2) factors, namely Organic fertilizer with the symbol "O" which consisted of 4 levels with each treatment namely O0 = 0 , O1 = 25 gr ,O2 = 50 gr ,O3 = 75 gr, and the second factor is Kalium chloride "K" which consists of 4 treatment levels, namely K0 = 0 , K1 = 6 gr ,M2 = 12 gr ,K3 = 18 gr. so that 16 treatments were obtained with 2 replications, then analysis of variance and F test level 5% was carried out. The results of this study were that the O0 value was significantly different from O2 and O3, but not significantly different from O1. The largest average plant growth was found in the K3.
