Abstract

This study was conducted to determine the effects of boron (B) and zinc (Zn) applications on biomass, dry weight content and grain yield of 25 registered and local populations of dwarf bean genotypes tested. Plants were grown for 3 B and 3 Zn doses (0, 5, 10 mg kg-1 each). The trial was conducted in three replicates within a controlled glasshouse according to randomized plots factorial design. Results have shown that B and Zn applications considerably effect on the dwarf dry bean varieties in terms of biomass, dry weight and grain yield. From the genotypes used, Eskisehir-855, Karacasehir-90, Noyanbey, Terzibaba, Yakutiye, Fasulye sira, Yalova-17, Romano, Nazende, Seminis Gina, Yunus-90, Akman-98, Z¨ulbiye, Horoz fasulye and Kanada were found to be resistant to B deficiency while Sehirali-90, G¨oyn¨uk-98, Akdag, Sahin-90, ¨Onceler-98, Aras-98, Sarikiz, Magnum, May Gina and Efsane were the sensitive ones. The highest grain yield at 10 mg B kg-1 application was attained from the species Aras-98 and Kanada, hence they were classified as resistant to B toxicity. Zinc x genotype interaction was found significant from the stand point of biomass, dry weight and grain yield. Akman-98, Karacasehir-90, Noyanbey, Terzibaba, Sahin-90, Horoz fasulye, Nazende and Efsane were tolerant to Zn deficiency, while G¨oyn¨uk-98, Aras-98 and Fasulye sira were moderately tolerant. On the other hand, the varieties Eskisehir-855, Yunus-90, Sehirali-90, ¨Onceler-98, Z¨ulbiye, Yakutiye, Romano and Kanada were moderately sensitive to Zn deficiency, while the species of Akdag, Sarikiz, Magnum, Seminis Gina, May Gina and Yalova-17 were highly sensitive.
