SILVA, Katiane S et al. Yield of cabbage cultivars depending on levels of boron. Hortic. Bras. [online]. 2012, vol.30, n.3, pp. 520-525. ISSN 0102-0536. http://dx.doi.org/10.1590/S0102-05362012000300027.
The cabbage crop is cultivated in small areas and requires much labor, this crop being mostly driven by family farmers. This study aimed to evaluate the effect of boron levels in different cultivars of cabbage in western Mato Grosso do Sul state, Brazil. The experiment was carried out at the Universidade Estadual de Mato Grosso do Sul, Unidade Universitária de Aquidauana. The experimental design was randomized blocks in factorial scheme 2 x 5, two cultivars and five doses of boron, with four replications. We evaluated the following features: boron foliar plant area, plant height, number of outer leaves, fresh weight of outer leaves, leaf content of boron, plant area, plant height, number of outer leaves, fresh weight of outer leaves, dry weight of outer leaves, classification according to head weight, compactness and yield per hectare. The cultivar 60 Dias showed higher values for yield components and consequently greater productivity. The application of boron influences linearly in the boron content of leaves, head diameter and number of inner leaves. The boron levels interfered the yield of cabbage, the maximum dose for '60 Dias' being 7.2 kg ha-1 and the minimum necessary dose for the cv. Chato de Quintal being 1.06 kg ha-1.
