Growth and Tomato Nutrition Content with Bandotan (Ageratum Conyzoides L) Bokashi Applied

Abstract

Bandotan (A.conyzoides) is one of the most common weeds in dry land. Weeds can reduce the results of a variety of crops. On the contrary, the use of this weed as the organic material would be able to increase the nutrient content of the soil. The problem is, the decomposition of this weed is naturally longer than the process in the form of Bokashi. This study aims to determine the effect of Bandotan applied in the form of Bokashi on growth and nutrient content of tomato plants. This study was an experimental study and completely randomized design was used with 5 treatments and 3 replications. The treatment were rate of bandotan bokashi those 100, 120, 140, 160 g / polybag and 0,6g NPK / polybag as a control. The research was conducted in the Screen House of Biology Department, Faculty of Mathematic and Sciences, Universitas Negeri Padang. Tomato growth observed was high, wet weight, biomass and weight of the fruit. While the nutritional quality of tomatoes was vitamin C and A. Data were analyzed using ANOVA and a further test DNMRT at 5% level. The results showed that bokhasi bandotan 120g / polybag give best effect to the weight of tomatoes. However, bandotan bokashi do not give effect to the high, wet weight, biomass, vitamin C and vitamin A of tomato. Bokashi bandotan can be utilized as a substitute for synthetic fertilizer NPK for tomato plants.
