Abstract: 

Abbandansar peat from a natural water tank, 5 kilometers southwest of Sari city (the Mazandaran province) was used in this research. Four rates of peat (0, 25, 50 and 75 percentage volume) were mixed with a sandy clay loam soil and a sand soil and their effect and also the effect of mere peat (100 percent) on growth indicator factors and concentration in plant tissues were compared in a completely randomized design with four replications in pots with tomato at vegetative, flowering and fruit set stages. Elements tested were N, P, K, Ca, Mg, Fe, Zn, Mn, Cu, Pb, Cd, Ni, Co and Cr. The growth indicator factors were fresh and dry weights, plant heights and root weights. The maximum dry weight was obtained with the 50 percent culture at flowering stage in soil mixtures and with 75 percent rate at flowering stage and fruit set in sand mixtures. Plant tissue zinc concentrations increased with increasing rates of peat in soil mixtures and copper decreased. Nitrogen, iron, lead and nickel were increased in sand mixtures. The quantity of available copper with this peat is not enough for a high yield in these mixtures and a greater yield could be expected with a foliar application of copper. For all treatments, with the first application of peat in this research, the levels of Ni, Pb, Cd, Co and Cr by plant analysis are lower than standard limits for plant and human toxicity. This peat is rich in plant available nitrogen, iron and is ideal for mixtures used in specific plant growth media and nursery with supplementary copper sprays applied.
