Effect of Seasons and substrates different on the quality of the compost produced by worms Eisenia fetida

Research to study the effect of seasons and substrates different on the growth and reproduction of the compost worm Eisenia fetida maker in 2012 in two seasons (spring and autumn), the dairy and livestock farming complex was Kangavar. The experiment was carried out in a factorial arrangement with the base of randomized complete block design in three repetitions. The first factor consisted of bed for eating worm (includes: 1– cow manure, 2- sheep manure, 3- 20% wheat straw + 80% cow manure 4- 80% sheep manure + wheat straw 20%, 5- 80% cow manure + 20% pea Straw, 6- 80% sheep manure + 20% pea straw, 7- 80% cow manure + 20% Fruit and vegetable waste 8- 70% cow manure +15 % corn straw + 15% Sawdust, 9- 70% cow manure +15 % Glycyrrhizins labra + 15 % wheat straw, 10- 70% sheep manure + 15 % corn straw + 15 % cardboard waste and 11- 70% sheep manure + 15 % Glycyrrhizins glare + 15% Sawdust) and the second factor is the different seasons (spring and autumn) respectively. Qualitative properties worm compost production traits include: pH, EC, organic carbon (OC), N (%), P (%), K (%), iron (mgkg-1), copper (mgkg-1) and zinc (mgkg-1), respectively. The results showed that the organic carbon (OC), nitrogen (N) in the treatment of - 70% sheep manure + 15 % corn straw + 15 % cardboard waste, pH and phosphorus in the manure of sheep, 70% + remains peas 20%, EC and zinc (Zn) in 70% cow manure +15 % corn straw + 15% Sawdust and iron (Fe) in treatment 80% cow manure + 20% Fruit and vegetable waste the highest was amount. Also in the all quality traits except yield of organic carbon, OC% and pH in the autumn with a greater amount of spring in the maximum amount that it can could Conditions environment and will be dependent on activity that makes vermicomposting worm higher quality.
