Using of organic matters such as vermicompost in culture bed has been considered widely due to its effect on soil property’s modification. Vermicompost increases soil water capacity and supplies plant needed materials resulted in high-yield rate as well as plant quality. To study the effect of vermicompost on tomato morphological and physiological characteristics, experiments were carried out twice in the year 2013 using a complete randomized block design with four treatments and 4 replicates in research fields of agronomy department, faculty of agriculture, Urmia University. Treatments include different vermicompost percentages (0, 25, 50, 75 percent) with garden soil and measuring parameters included root length, stem length, fresh and dried weight, chlorophyl, sugar and prolin contents of the plants. After initial analysis of data, metaanalysis was performed. Results showed that using vermicompost increased all the measuring parameters significantly in general and with the highest rate of vermicompost in particular. In this regard, the paramount effects were pertained to plants root length as well as plant height in comparison to the other treatments. https://www.biotech-asia.org/vol12_nospl_edn2/the-impacts-of-vermicompost-on-tomato-morphological-and-physiological-characteristics/ Tomato; Vermicompost; Met analysis; Morphological and physiological characteristics
