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

Abstract

This study was carried out in a greenhouse in 2021 to determine the boron response of some bean cultivars at increasing levels of boron doses. The experiment established according to the complete randomized design with three replications was applied to 15 registered bean cultivars at 0, 5, and 10 mg B/kg doses using Na2B8O13.4H2O (20.8% B) fertilizer. The above-ground organs were harvested during the blooming period, and the cultivars of Befficient and B-tolerant were determined in the investigation of their dry weight, B content, and concentrations. Dry weights increased by 1% (Doruk, 10 mg B/kg) and 38% (Kantar-05, 5 mg B/kg) under B conditions, compared with the non-treatment group. Furthermore, insufficient B levels in the soil conditions were evaluated as B-efficient bean cultivars having a dry weight above the average, but cultivars having a dry weight below the average were named Btolerant cultivars. As a result of the study, it was determined changing depends on the boron application of boron efficient (B-effect) and boron tolerant (B-tolerant) bean cultivars. Cihan, Güngör, Berrak, Elkoca-05, Özdemir, Kantar-05 and Arslan cultivars were confirmed as B-efficient, although Zülbiye, Sururbey, Doruk, Göksun, Karacabey, Özmen, Battallı and Zirve cultivars were determined as B-tolerant cultivars. As a result of the study, it was determined that the efficient boron cultivars were Zülbiye, Zirve and Battallı, while the boron tolerant cultivars Cihan and Arslan.
