Abstract

Sanitary disposal of agricultural wastes is considered among the major problems in waste management. The bioorganic fertilizer production using vermicomposting method with usability in agriculture is one of the proper management practices for such wastes. This study was conducted to evaluate the capability of producing fertilizer using saffron petal wastes by vermicomposting method. First,certain proportions of cow manure and agricultural waste obtained from saffron petals wastes were produced in five different ratios,and then resulting fertilizer was tested in pilot conditions. In all steps,pH,total organic carbon and Kjeldahl nitrogen were measured and recorded using the standard method,in addition to temperature and moisture control of the masses to achieve the appropriate time and fertilizer products. The results showed that the most appropriate biological fertilizer was produced in sustainable conditions,including 65 to 75 moisture,temperature of about 24 °C in treatment of 46 saffron petal wastes mixed with cow manure. Saffron petal wastes has suiatable ability of conversion to bio-organic fertilizer using vermicomposting method. © 2016,International Journal of Pharmacy and Technology. All rights reserved.
