Coco peat is a mixture of processed coconut fruit crusts, which is physically a porous material similar to peatmoss. This product is widely used in gardening industries in Europe, Australia, and in recent years in the United States and Canada. Due to the development of greenhouse crops and especially soilless cultivation systems, the use of this material has been increasing as bedding materials, which causes the withdrawal of capital from the country. Therefore, application of other alternatives that are produced from local and cheap materials, can reduce the production costs and also help to increase the job creation and national income. Mulberry and pine are the dominant trees in Isfahan urban landscape, producing huge amounts of residual pruning chips, pine leaves and cones annually. Disposal of these residues is now a headache for the city authorities, while they may be converted to valuable plant bedding materials. Therefore, in this study, the feasibility of vermicomposting of mulberry prunes and pine leaves and cones to replace coco peat for growing tomato in a soilless culture system was investigated. In a six month incubation period, the raw residues, ordinary composts and NPK enriched composts of the residues were converted to vermicomposts as the experiment bedding materials. The experimental materials were analyzed for different physico-chemical properties as: bulk density, water holding capacity, EC, pH, cation exchange capacity, nutrient and hemicellulose, cellulose and lignin content and C/N ratio before and after vermicomposting. A coco peat sample was also analyzed for comparison. Some growth indexes of worms were also monitored during the vermicomposting period in the treatments. The water holding capacity of coco peat was much higher than other experimental materials. The bulk density of the residues was not changed by vermicomposting except in pine leaf and enriched compost of pine leaf in which the vermicomposting increased the bulk density. The electrical conductivity, pH, cation exchange capacity, lignin and cellulose content increased in vremicomposts, except for mulberry prunes enriched composts, and hemicellulose decreased (except for pine leaf) compared with the raw materials. The vermicompost of the mulberry prunes showed a cellulose content close to the coco peat sample. Regarding the worm growth parameters, the highest number and weight of worms, for the first and second 3-month incubation periods, observed in pine leaf and the lowest values were related to pine leaf enriched compost. The produced vermicomposts and their primary materials as well as a coco peat sample all mixed, 50/50 by volume, with perlite examined for tomato growing using a completely randomized design. The mixed beddings placed in 2 Kg capacity pots and a tomato seedling planted in each pot. The plants were grown in a greenhouse with natural light, 18-25 0 C, and irrigated 4-5 times daily using a Johnson nutrient solution. After 2 months the plants were harvested and the yield parameters were analyzed using SAS software and LSD for comparison of means at 5% level. The results showed that with respect to the number of leaves, stem diameter, shoot dry weight, and number of fruits the plants grown in vermicompost of mulberry prunes enriched compost were superior to other treatments and in terms of fruit weight plants grown in vremicompost of pine cone enriched compost showed the best performance. In conclusion the vermicomosts of the enriched composts especially chips prunes and pine cones enriched composts were somewhat superior to the coco peat and may be considered as suitable alternatives for coco peat in hydroponic bedding. Althogh further studies will be needed for different crops, in this regard. Keywords : Hydroponics bedding, Pine Cones, Pine Leaves, Mulberry Pruning chips, Coco peat, Tomato
