Abstract

in the treatments were grouped using Duncan's multiple range tests Results and discussion: The effect of urban waste compost, the effect of Nitrogen and their interaction on yield of tomatoes were statistically sigNificant at the level of one percent. The highest yield of fruit 68785 kg ha-1 was obtained from 20 ton. ha-1 compost with 100 kg ha-1 Nitrogen. Researchers have linked this increase to the positive role of urban waste compost in improving physical and chemical properties of soil (Hu and Barker, 2004). The results of various systems of cultivation and ecology studies related to the use of orgaNic fertilizers indicate positive results from the common use of chemical fertilizers and orgaNic resources in the framework of integrated plant nutrition systems (Seilsepour, 2017). Consumption of 20 tons per hectare of urban waste compost sigNificantly increased the concentration of lead, cadmium and Nickel in tomato fruit at 2804, 2400 and 3022 percent, respectively, compared to control. However, the concentration of any of the above elements in fruit was not more than the maximum allowed national standard of the country. Increasing the concentration of heavy metals in tomato fruit has also been reported by other researchers (Asgharipour and Armin, 2010). Also, muNicipal waste compost increased the concentration of total lead, Nickel and cadmium in soil, which was allowed in this concentration increase. Also, there was a sigNificant Correlation between the concentration of lead, cadmium and Nickel of tomatoes with total concentration of these elements in the soil, whose regression equations followed the linear model Conclusion: The results of this study showed that the combination of muNicipal waste compost with Nitrogen is the most suitable compound for increasing the yield of tomato. The highest yield of fruit is obtained from the application of 20 t ha-1 of muNicipal waste compost with 100 kg ha-1Nitrogen. On the other hand, utilization of muNicipal waste compost increased the concentration of heavy metals in the fruit and soil, but this increase was allowed in the range of 20 tons per hectare of muNicipal waste compost. However, despite the positive effects of using muNicipal waste compost on the performance of tomatoes, it is recommended that the use of this substance be carried out with caution and continuously increasing the concentration of heavy metals in the soil and crop yield and be taken into consideration.
