Khomami, Ali Mahboub (Haddad, Alireza)
To determine the effects of vermicompost cow dung and vermicompost cow dung+ sawdust (about 80% volume to 20%) with Peat in Peat+ perlit (volume 1: 2) growth media on five ornamental foliage plant,s Dieffenbachia, Aglaonema, Dracaena, Spathiphyllum and Ficus benjamina. First sawdust introduce to worm and then the production of vermicompost, rooted stock planted in Peat+ perlit (volume 1: 2) and beds with 25, 75, 50, 100% vermicompost of cow dung + sawdust that substituted with Peat (Peat+ perlit). Some factors as a nitrogen, phosphorus, potassium, calcium, magnesium in leaves and Growth media. Height, diameter, Shoot and leaf fresh and dry weight, Root fresh and dry weight of plant according to plant were measured. The results showed that the increase in levels of two kind vermicompost in substituted with Peat significantly increased, nitrogen, phosphorus, potassium, calcium and magnesium in Dieffenbachia; and nitrogen, phosphorus, potassium in Aglaonema, Dracaena, Spathiphyllum and Ficus benjamina leaves. With increasing vermicompost level, container capacity increased in comparison to peat and% 100 vermicompost has the highest Container capacity. 25% of two kind's vermicompost in comparison with control increased height, diameter, Shoot and leaf fresh and dry weight, and is advisable.
