Study of Variety and Compost Fertilizer Dose of Cow Dung Against Productivity at Cauliflower (Brassica oleracea var. botrytis L.) in Kediri City Low Plain

The study of cow dung compost and productivity cauliflower varieties in lowland. The aims to : determine the influence of the interaction and relationship of cabbage varieties composted cow manure fertilizer on crop production cauliflower and dose of cow manure compost optimum in some varieties of cauliflower (Brassica aleracea var. botrytis L.), grown in lowland Kediri. Research methods using factorial treatment design consisting of two treatments and environmental design group randomized design, which consists of three groups. The first factor : cauliflower varieties, consisting of three levels, namely : varieties Sakata (V1), varieties Bima (V2), varieties of IPM 126 (V3) and the second dose of fertilizer of cow dung compost (S), consists of four level, namely : S1 = 0 ton/ha , S2 = 2 tons/ha , S3 = 3 ton/ha, and S4 = 4 tons/ha. The results showed that: occurs significant interaction effect of varieties and fertilizer compost manure to crop production cauliflower and production of heavy cauliflower varieties produced by Sakata optimum dose of compost manure 6,38 at tons/ha, varieties Bima at 8.3 tons/ha and varieties IPM 126 at 5.51 tons/ha .
