Abstract

The research aimed to study and compare the result of organic compost with fermented bio-extracts from Agricultural Waste and chemical fertilizer on Hybrid Cauliflower White Baron production. The experiment plan was based on Randomized Complete Block Design (RCBD). The experiment was divided into 5 treatments (T) and each treatment contained 3 replications. T1 used 13 – 13 – 21 chemical fertilizer at 100 kg/rai. T2 used Bokashi composting and chicken manure bio-extract. T3 used Bokashi composting and cow manure bio-extract. T4 used Bokashi composting and pig manure bio-extract. T5 used Bokashi composting and fruit peel bio-extract. The experiment showed that the used of 13 – 13 – 21 chemical fertilizer resulted in the highest average plant height, average leaf number, average plant weight, average yield per m² and flowering percentage at 28.26 cm, 12.48 leaves, 358.76 g 1.52 kg/m² and 46.10% respectively. The result was statically different. The result also showed the tendency of highest flower diameter and grade B production i.e. 5.52 cm, and 48.80%, respectively. Yield that could not pass the grading was medium. This followed by T2 with the average height of 22.29 cm and average 10.79 leaves per plant. The average yield was 0.52 kg/m² with flower percentage of 23.40% and flower diameter of 3.45 cm.
