PENGARUH PUPUK ORGANIK CAIR CROCOBER TERHADAP TANAMAN BAWANG MERAH (Allium ascalonicum L.)

Research on the effect of liquid organic fertilizer (LOF) Crocober application to the onion crop (Allium ascalonicum L.) had been conducted in Sub Kajai, District Lemur, Solok regency for 3 months starting from May to July 2015. The goal was to get the POC concentration and Crocober frequency to increase growth and yield of onion crop. Experiments using a randomized block design in a factorial that consists of 2 factors. Factor 1 was 5 concentrations LOF was 0% (P0), 2.5% (P1), 5% (P3), 7.5% (P4) and 10% (P5) while Factor 2, was the frequency of POC application consists of two levels ie; once a week (weekly) and once of two weeks. Data obtained and analyzed variance. If the F count larger than F table 5% followed by a test of the Duncan Multiple Range Test (DMRT). The experimental results indicated that application of 5% POC Crocober concentration given weekly was the exact interaction to improve the growth and yield of onion with the result reached 13.83 tons/ha.
