Milk thistle (Silybum marianum L.), belonging to the Asteraceae family, is an annual plant and prefers light and fertile soils. Silymarin is the most important compound extracted from the seeds of this plant and it is used in the treatment of liver diseases, hepatitis, cirrhosis and liver cancer prevention. In usual agricultural systems, the purpose of using fertilizers and their combination is to obtain the highest seed yield and quality of the active substances. In order to investigation of the effect of different fertilizers and their combination on some quantitative and qualitative characteristics of milk thistle, an experiment was arranged in split plot in a randomized complete block design with three replications in the Research Farm of Agricultural Institute, University of Zabol, during 2013-2014. In this study, the main factors were Hungary genotype (A1) and Mashhadi population (A2) and the sub factors were application of different fertilizers such as control treatment, manure, chemical fertilizer (urea + ammonium phosphate + potassium), mycorrhizal fungi (Glomus mossaea), combination of nitroxin, bio-sulfur and bio-superphosphate, combination of chemical fertilizer and manure, combination of mycorrhizal fungi and manure, and nano-iron chelate. The results showed that there was not any significant difference between Hungary genotype and Mashhadi population. Totally, the mycorrhizal fungi (G. mossaea) was the best treatment than other fertilizer treatments in the milk thistle plant and it caused enhancing the growth and better activity of photosynthetic pigments as well as improved seed yield and increased silymarin substance in the milk thistle plant.

To study the effect of biological and manure fertilizers on economic yield and quality characteristics of roselle (Hibiscus sabdariffa L.), an experiment was conducted as split plot based on a randomized complete block design with three replications at the Agricultural Research Center of Zabol University, Iran during growing season of 2012. Treatments included three manure levels; 0, 10 and 20t.h-1 and eight levels of biofertilizer including control, nitroxin, bio-sulfur, biological phosphorus, nitroxin+bio-sulfur, nitroxin+biological phosphorus, bio-sulfur+biological phosphorus, nitroxin+bio-sulfur+biological phosphorus. Different levels of manure fertilizer and biofertilizers were considered as main plots and subplots, respectively. Traits included economic yield, leaf SPAD, chlorophyll a, b, carotenoids, carbohydrates, anthocyanin, protein, potassium and phosphorus. According to the obtained results different levels of manure and bio-fertilizer treatments and their interactions on biological traits were significant. The maximum economic yield (1290kg.h-1) and protein content (841.42mg.g-1) was obtained with a combined consumption of 10 tons of manure per hectare and nitroxin. The highest amount of anthocyanins (0.45μg.g-1) and carbohydrates (1035.7μg.g-1) in sepals was obtained at 20t.h-1 manure+bio-sulfur+biological phosphorus. The use of 20t.h-1 manure and nitroxin, bio-sulfur and biological phosphorus caused an increased leaf SPAD, chlorophyll a, b, carotenoids, phosphorus and potassium as compared to control. Our results clearly showed that combined use of manure and biological fertilizers could play an important role in increasing the economic yield and quality characteristics of roselle in comparison with the separate consumption.
