A weed is a plant that is considered to be nuisance and unwanted plant in human-controlled settings,especially farm field and garden. The weed that grow in surrounding of crop could decrease yield due to competitionoccur between weed and crop on nutrition, sunlight and water. Organic farming system which has been developednowadays is an environmental friendly organic farming system. The objective of this research is to determine weedcompetition on carrot using several kinds of organic fertilizer. Six treatments were used in this research, i.e., greenmanure, combination of green manure and EM, EM alone and control (without manure and EM). The weed wasgrowth together with carrot for 3 months. The parameters are wet weight and dry weight of carrot per meter square.The results show that manuring could increase weed competition which in turn wet weight and dry weight of carrotare decreasing. The highest competition between carrot and weed occurred in the treatment of combination betweenorganic manure which combines with EM. The added EM on organic manure could increase weed competition oncarrot.

Solid organic fertilization in organic farming practices should be supplemented with liquid organic fertilizer to accelerate the availability of plant nutrients. The study aimed to determine performance and major nutrient uptake by sweet corn following application of vermicompost supplemented with liquid organic fertilizer (LOF) and to find out combined vermicompost and liquid organic fertilizer for sweet corn production. The experiment was conducted at CAPS Research Station (1054 m above sea level) from April to June 2016, arranged in split plot design with 5 rates of vermicompost as the main plot and 5 rates of LOF as the subplot. Rates of vermicompost comprised 5, 10, 15, 20, and 25 Mg ha-1, while LOF rates consisted of control, 25, 50, 75, and 100% (initial concentration). Treatment combination was replicated 3 times. Root application of LOF was carried out every week at 2-8 weeks after planting (WAP) with total volume of 950 ml plant -1. Result pointed out that vermicompost pronouncedly raised nitrogen (N), phosphorus (P) and potassium (K) uptakes and linearly enhanced growth and yield of sweet corn, indicated by plant height, plant leaf area, shoot fresh and dry weight, weight of husked and unhusked ears, diameter of ear, and weight of husked ear per plot but length of ear. The addition of LOF had a similar effect on major nutrient uptake, growth, and yield of sweet corn. Vermicompost at the rate of 25 Mg ha-1 supplemented with 100% LOF provided greatest growth and yield, suggesting that the fertilizer combination was the most effective complementary organic fertilization for sweet corn production in the organic farming system.
