DUDA University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca, Romania, 3-5 Manastur str., Cluj-Napoca, Romania, simonavaida2@gmail.com Abstract. In the experimental field of UASVM Cluj-Napoca from Jucu we performed, between 2008-2010, a series of research on the behavior of eight varieties of marigold, in three conditions of soil fertilization with manure. The average yearly air temperature is 10.71 º C Jucu in 2008, 11.12 º C in 2009 and 11.21 º C in 2010 and during the growing season (aprilie-sept.) of 17.70 ° C 19.07 ° C and 18, 08 ° C. In terms of rainfall, 2008 was very dry (less than 150 mm from the annual average), 2009 excessively dry (less than 250 mm annual average) and 2010 was very wet (83 mm more than the annual average). Climatic conditions were favorable to grow marigolds. A series of biometric measurements have been conducted on the eight varieties of marigold, such as waist measurement of the average plant, the production of flowers and drying efficiency, the correlation between average plant size and production. Average plant size in eight varieties of marigold, in 2008-2010 was between 67.44 and 84.78 cm. Production of fresh flowers was between 7400 and 8507 kg / ha. The biggest production of inflorescences was obtained from varieties of ”Belezza del Pacifico”, ”Cluj 2” and ”Starsem 922”, with over 9.000 kg / ha of fresh flowers. Production of Marigold is strongly influenced by genotype and fertilization. The average yield of drying was 6 / 1. Between the average height of marigold plant and production there's a direct link. The increase of production is influenced by the average size of marigold plant. Keywords: marigold, cultivation, plant size, production of inflorescences. INTRODUCTION Marigolds are herbaceous plants, annual, known for their herbal purposes (LS Muntean et al., 2007).The name in English, "Marigold", comes from the word "gold" and association with St. Mary, hence the "Mary's Gold", respectively Marigold (gold St. Mary) (Maria Gonceariuc, 2008). Marigold’s therapeutic action is anti-inflammatory (through saponosids), anti-infective, anti-tumor, antispasmodic, cholagogue, soothing, emollient, astringent, protective (immune, antioxidant), healing, choleretic, perspiration, sedative, bactericidal, antiviral, antitrichomonazic. In this paper we present the results of the cultivation of eight varieties of marigold, under different fertilization with manure, in the experimental field of Jucu - Cluj, in 2008 - 2010. MATERIALS AND METHODS Experiences began in the experimental field of Jucu - Cluj, in 2008, over three years. They used eight varieties of marigold "“Petrana”" (Romanian variety) "Cluj 2" (local population), "Novi Sad" (local population); "Agrosel 696" (commercial variety), "Starsem 922 " (variety of trade); “Belezza del Pacifico” (the trade), “Diana” (sort of Moldova) and
