Application of Cow Manure and Mycorrhiza on the Growth of Biduri (Calotropis gigantea) a) Study Program of Agrotechnology, Faculty of Agriculture, Universitas Sebelas Maret, and Center for Research and Development of Biotechnology and Biodiversity, LPPM Universitas Sebelas Maret, Jl. Ir. Sutami 36A Surakarta 57126 - Indonesia Abstract Biduri (Calotropis gigantea) is a herbaceous plant that has a lot of potentials yet farmers do not cultivate it properly. For instance, many farmers apply inorganic fertilizers excessively which can damage the environment, so that they do not embody environmentally-friendly agriculture. One of the efforts to achieve sustainable agriculture is the use of organic fertilizers. This research was carried out from March 2021 to October 2021 at the screen house, field laboratory of Jumantono, Soil Biology laboratory, Chemistry and Soil Fertility laboratory, and laboratory of Plant Physiology and Biotechnology, Faculty of Agriculture, Universitas Sebelas Maret. This research used a Randomized Complete Block Design (RCBD) with two factors and three replications. The first factor is cow manure which consists of three levels: K0 = without manure, K1 = 10 tons/ha, K2 = 20 tons/ha. The second factor is mycorrhiza which consists of four levels: M0 = 0 g/plant, M1 = 5 g/plant, M2 = 10 g/plant, M3 = 15 g/plant. The data obtained were analyzed by analysis of variance and DMRT. The results showed that the interaction between cow manure and mycorrhiza was not increase the growth of biduri- giving a dose of cow manure 20 tons/ha gives best result for the yield of plant height, stem diameter, number of leaves, and number of branch- mycorrhizal administration was not increase the growth of biduri.
