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 × 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.

This work aimed to assess the effects of different sources and dosages of nitrogen (N) in the development and productivity of sweet corn (Zea mays convar. saccharata var. rugosa). The experiment was carried out at São Domingo Farm, in Palmeiras de Goiás, state of Goiás, during the agricultural season of 2010-11. It was used the experimental design of random blocks with parcels subdivided in three replications, which required 36 treatments, the area of each parcel being of 25.6 square meters (3.2 m/8 m). Each N source (Novatec™, urea, ammonia sulfate) corresponded to a parcel. The sub-parcels were formed by the following N dosages: 0, 50, 100, and 150 kilos per hectare. During the flowerage period, the following morphological elements were assessed: plant and ear height and stalk diameter. The harvest took place in March 3, 2011, between the milk grain and dough grain stages. Ears were cropped and then identified through treatment. After that, the following variables were assessed: ear and cob diameter, number of grain per row, grain and ear length, plants final population per hectare, number of ears per hectare, and corn straw green mass per hectare. The growing of sweet corn in the soil and climate characteristics of Palmeiras de Goiás responded positively to the increase of nitrogen fertilizer no matter what the N source may be.
