Journal Title: Journal of Herbal Drugs - Year 2013, Vol 3, Issue 1
Abstract
Background & Aim: Cassia angustifolia Vahl is a valuable medicinal plant that it is important for constipation treatment. According to the importance of organic agriculture in increasing the yield of medicinal plants, the effect of bio-fertilizer on quantities yields of Cassia angustifolia Vahl or Senna in Karaj region (Iran) was examined. Experimental: This research was carried out in Randomized Complete Block Design (RCBD) with four replications and 13 treatments in 2009-2010. The seeds of Senna were scratched with H2SO4 (73%), then the bio-fertilizers and chemical fertilizer were added before sowing. The leaf surface and its Chlorophyll content (SPAD) were measured with Delta-T and Chlorophyll-meter. Results & Discussion: The highest effect on quantities yield of plant was obtained from chemical fertilizers treatment. The bio-nitroxin and mixture of two bio-fertilizers (bio-sulfur and bio-phosphate fertilizer) increased quantities yield of this plant. The fertilizer treatments had a significant effect on plant height, stem diameter, chlorophyll content, leaf area, leaf dry weight and leaf fresh weight (ppIndustrial and practical recommendations: Additive Nitroxin as bio-fertilizers in soil for increasing quantitative yield of Cassia angustifolia Vahl is recommended.
