Research on some methods appropriate for organic farming on weed species in tomato cultivation

This study was conducted to determine the effect of some weed control methods used in organic farming against weeds in greenhouse and field tomato in Adana provinces of Turkey in the years 2007-2009. Aplicated methods in the study were; solarization, mulching (mulch textile, corn stalks mulch and peanut shell mulch), hoeing (hand hoe, push hoe, cultivator, rotary cultivator) and brushing (horizontal rotating brush weeder). Effect of these applications on all weeds, important weed species in the trial areas and tomato yield were determined in this study.As a result of studies mulch textile (geotextile) was the most effective application and no weeds arise on this material both greenhouse and field tomato, solarization was controlled annual weeds and tomato yields were higher in geotextile and hand hoe applications. Mulch textile is recommended due to be more efficient, economical and advantageous compared to other synthetic mulches for controlling weeds especially in organic farming systems
