This study examined the effects of organic fertilizers and organic waste materials on Aloe vera yield and growth parameters in 2012 in green house, in Ghasr-e-Shirin, Iran. The experimental design was completely randomized design with three replications, nine treatments and 27 experimental pots. Treatments included organic fertilizers and organic wastes: pigeon manure, palm waste and vermicompost, which every one was used in three levels: 1.5, 3 and 4.5 weight percentage equivalent to 90, 180 and 270 gr. In addition to these treatments, one treatment without fertilizers and organic waste material was considered as the control. At the end of plant growth period, the number of new leaves in each pot, leaves fresh weight, leaf diameter, leaf length, leaf gel percentage, leaf cuticle percentage and chlorophyll index were measured. Analysis of variance indicated that all fertilizers and organic waste materials increased Aloe vera growth parameters. The highest numbers of leaf and fresh weight, leaf diameter and chlorophyll index were achieved when 3% pigeon manure was applied.
