Özet

This research was conducted to investigate the effects of phytostimulators application (Messenger, Crop-Set, ISR-2000) on yield and morphological parameters of common bean cultivars grown under four irrigation regimes [25% (I-25), 50% (I-50), 75% (I-75) and 100% (I-100)]. phytostimulators reversed the negative effect of drought on plant growth. Significant interaction was determined for all parameters except stem diameter and stomatal conductivity between phytostimulator and drought applications. The best effect on stomatal conductivity was provided from ISR-2000 (23.5% reduction) application. The highest yield was obtained from the 25% water deficiency applied with 1.91 ton per hectare. It was determined that the best results were obtained from Messenger in Efsane and Asya cultivars and ISR-2000 in the Oz Ayse cultivar on yield. Therefore, it was concluded that the use of phytostimulators under drought stress is important for the effective use of water.
