Study some of characteristics quantitative Herb milk thistle (Silybum marianum L.) in response to organic and biological fertilizer

In order to investigate the effects various levels of organic and nitroxin biological fertilizer on quantitative characteristics and yield of Silybum marianum L., This experiment was conducted in a randomized complete block design with seven treatments and three replications at the Agricultural Research Station of Firdausi University of Mashhad, Iran, in 2012. Treatments consisted of: control (no fertilizer), two levels of cow manure (30, 15 t/ha), two levels of poultry manure (15, 7.5 t/ha), integrated fertilizer (cow manure 15 T/ha and poultry manure 7.5 t/ha) and nitroxin biological fertilizer (400 mg/m2).plant responses consisted of plant highet, flowering stem highet, capitol diameter, main capitol number, subordinate capitol number, total capital number, number of seed in per capitol, 1000-seed weight, seed yield, oil yield and oil percentage per hectare. The highest number of seed in capitol, plant height, flowering stem height, capitol diameter, 1000seed weight (27/66 Gr), and highest seed (2024 Kg/ha) and oil (476 Kg/ha) yield found at 30 T/ha of cow manure. The Nitroxin biological fertilizer application on the seed number and 1000-seed weight had a significant.The result showed to obtain the highest yield and organic production in cultivated of Sylibum marianum and replacement for chemical fertilizers the application of cow manure (30 T/ha) recommended.
