Evaluating of Bean (Phaseolus vulgaris L.) Cultivars for Boron Efficient and Tolerant

Abstract

This study was carried out in a greenhouse condition in 2021 to determine the boron response of some bean cultivars at increasing levels of boron doses. The experiment established according to the Random-ized Complete Block Design with three replications was applied to 15 registered bean cultivars at 0, 5, and 10 mg/kg B doses using Etidot-67 (20.8% B) fertilizer. The aboveground organs were harvested during the blooming period, and the varieties of B-active and B-tolerant were determined in the investigation of their dry weight, B content, and concentrations. It was confirmed that the cultivars' dry weights increased at a varying ratio between 1% (Doruk, 10 mg/kg B) and 38% (Kantar-05, 5 mg/kg B) when boron applications were compared to the control groups. Insufficient B levels in the soil conditions were evaluated as B- active bean cultivars having a dry weight above the average, but varieties having a dry weight below the average were named B- tolerant cultivars. As a result of the study, it was determined changing depends on the boron application of boron active (B-active) and boron tolerant (B-tolerant) bean varieties. Cihan, Güngör, Berrak, Elkoca-05, Özdemir, Kantar-05 and Arslan varieties were confirmed as B-active although Zülbiye, Sururbey, Doruk, Göksun, Karacabey, Özmen, Battallı and Zirve cultivars were determined as B-tolerant cultivars. The results showed that the highest boron efficiency in B-active cultivars and the lowest in B-tolerant cultivars Zülbiye (98) and Zirve, Battallı (85) cultivars, Cihan (82) and Arslan (70), respec-tively.
