The objectives of this research were to examine the chemical properties of the growing media and the effect of growing media on growth of lactuca sativa. The experimental design was performed with 4 replications and 7 treatments in Completely Randomized Design (CRD). The treatments were 1) loam: rice straw: chicken manure: coconut coir (1:1:1:1) 2) loam: corn cob: chicken manure: coconut coir (1:1:1:1) 3) loam: soybean residue : chicken manure: coconut coir 4) loam: rice straw: corn cob: chicken manure: coconut coir (1:1:1:1) 5) loam: rice straw: soybean residue: chicken manure: coconut coir (1:1:1:1:1) 6) loam: corn cob: soybean residue: chicken manure: coconut coir (1:1:1:1:1) and 7) loam: rice straw: corn cob: soy bean residue: chicken manure: coconut coir (1:1:1:1:1). At the end stage, the pH was 8.02 - 8.34. The EC was ranged between 5.92 - 6.37 dS/m. Total N, total P and total K were ranged between 0.36 - 0.59 %, 0.55 - 1.06 % and 0.83 - 1.38 %, respectively. When planting materials and vermicomposting tea are tested against the growth of green oak salad, it is found that the height, leaf number, canopy and weights of tree are different. Treatment 3 (planting material: commercial planting material) has maximum height, copony and weights. Treatment 2 (planting material) has the highest number of leaves.
