The conventional tomato cultivation methods require the use of enormous quantities of chemical inputs, which can impair the health-promoting properties of fruits. The present study was undertaken to search for alternatives methods bearing minor risks for human health and environment friendly. Powders of Solanum aculeastrum and Tithonia diversifolia were applied on the soil and their aqueous, chloroform and hexane extracts sprayed on the aerial parts of tomato plants. Of a total of 19 parameters measured 12 were significantly improved after treatment of tomato plants with chloroform extract of T. diversifolia, 10 as a result of foliar sprays of aqueous or hexane extract of T. diversifolia, 09 as a result of soil enrichment with the powder of T. diversifolia, 05 after foliar application of hexane extract of S. aculeastrum, 03 after spraying of aqueous extract of S. aculeastrum on aerial parts, 02 as a result of treatment with chloroform extract of S. aculeastrum and 01 as a result of soil amendment with the powder of S. aculeastrum.
