    Palm leaves as organic material can be used as compost. Can be accelerated composting and compost quality can be improved by providing additional material such as plant ash and lime. Organic materials have a role to improve soil structure and nutrient availability, soil with compost will be fertile, so it's good for crops such pakchoy plants, because plants pakchoy have shallow roots. The purpose of this study was to determine the best supplemental material on palm leaf compost so as to provide a good influence on the growth and development of plants pakchoy (Brassica chinensis L.). This experiment was conducted last for (3) months, starting in October-December 2011. This research was conducted using completely randomized design with 3 treatments and 6 replications. The treatment is an additive in the manufacture of palm leaf compost that consists of 3 types : T1 agricultural lime , T2 ash sawdust, T3 rice husk ash. Then conducted further tests with BNT at the 5% level. Parameters measured were Plant Height (cm), number of leaves (strands), Fresh Weight (grams), Leaf Area (cm2). From the results of this study concluded that the provision of some kind of additional materials for the manufacture of palm leaf compost on the growth and yield of pakchoy provide tangible results did not affect the growth of plants pakchoy. This is because compost has not decompose completely so that the plant can only utilize the nutrients in the soil that is used as a growing medium.
