Abstract
The experimental field UASVM Cluj-Napoca, from Jucu in 2008, we made some research on the behavior of eight marigold varieties in three conditions of soil fertilization with manure. The year 2008 was characterized by an amount close to average rainfall, but a mean temperature of the vegetation period increased by 6.7°C. Climatic conditions were favorable marigold cultivation.
 The marigold cultivars have made a number of biometric measurements such as waist measurement of average plants, diameter of inflorescences, inflorescence mass of 100, the production of inflorescences and drying efficiency.
 Plant size in the eight varieties of marigold was between 64 and 92 cm. Average diameter of inflorescences was between 4.7 and 8.25 cm. Mass of 100 marigold inflorescence ranged from 240 to 90 g and the production of fresh inflorescences was between 6,890 and 10,200 kg/ha.
 Yields the largest inflorescence was obtained from cultivars „Belezza del Pacifico", "Cluj 2"and "Starsem 922", with over 9600 kg fresh inflorescences /ha. Production at marigold is strongly influenced by genotype and fertilizer. The average yield was drying 6 / 1. There is a direct correlation between size and mass of their inflorescences.
