Effect of different organic fertilizers on soil physicochemical properties, production and biomass yield of tomato (Lycopersicon esculentum L.)

In order to study the effect of organic and chemical fertilizers on soil physicochemical properties, production and biomass yield of tomato (Lycopersicon esculentum L.) an experiment was conducted with randomized complete block design in 3 complete blockes and six treatments at the experimental farm of the Environmental Science Research Institute of Shahid Beheshti University in 2006. Treatments were Vermicompost (VC) from municipal solid waste, municipal solid waste compost (MC), Cow manure (CM), poultry manure (PM), chemical fertilizer (CF) and no fertilizer as a control (NF). Results showed that the treatments had significant effect (p≤ 0.01) on percentage of organic carbon, organic matter, total nitrogen, the availability of phusforus, potassium, pH and CEC, SP of soil but had not significant effect on EC of soil. Also content of soil micro element affected by treatments and amount of these parameters were increased by using of organic fertilizers. Treatments had significant effect (p≤ 0.01) on soil physical properties such as buck density, porosity and but had not significant effect on aggregation of soil. Biomass production of tomato were increased by using of chemical and organic fertilizers compare in control treatment and the highest value of biomass and economic yield were obtained in VC and CF treatments. As a result using of organic fertilizers especially in composted form had positive effect on soil health and fertility, which consequents increase yield in long term can be expected.
