Abstract

Commercialization of agricultural operations and use of pesticides and chemical fertilizers in agricultural production has been created serious environmental impacts. Due to this issue and in order to assess the amount of chemical fertilizer and pesticide inputs in saffron and wheat production systems, a study was conducted in Qaenat region (South Khorasan province), 50 wheat fields and 48 saffron fields were investigated during 2011-12. The results showed that average nitrogen fertilizer consumption was 222.38 and 57.83 kg.ha-1 in wheat and saffron production systems, respectively, which from sstatistically point of view the difference was significant. In addition, unlike wheat, the use of pesticides very low in saffron cultivation and in many saffron farms it was zero. Therefore, the results can be considered saffron is an healthier product and have greater potential to organic product. Also, the amounts of nitrogen, phosphorus and potassium fertilizers which were using in wheat in the study area were significantly different with recommended values. While in saffron production there was no significant difference between the values of consumed and recommended. Therefore, it seems, performing soil testing in each region and providing appropriate fertilizer formulas and required promotional-educational services in this regard, and raising public awareness is a good strategy for reducing the use of chemical inputs.
