A bananeira (Musa spp.) é uma planta monocotiledônea herbácea, apresentando caule subterrâneo (rizoma) de onde saem as raízes, em grupos de três ou quatro, totalizando 200 a 500 raízes. O diâmetro predominante das raízes é de 0,2 mm a 0,3 mm, sendo que 60% do sistema radicular estão concentrados na profundidade de 0 a 30 cm e 80% entre 0 a 50 cm, O pseudocaule é formado por bainhas foliares, terminando por uma copa de folhas compridas e largas, com nervura central desenvolvida. É uma planta cultivada de norte a sul do país, em diversos tipos de solos.

A pesquisa busca caracterizar os sistemas de produção das pequenas unidades familiaress dos tabuleiros costeiros do sul de Sergipe, observando que em decorrência da política de subsídio implementada pelo geoverno, verificou-se uma rápida elevação da produção de frutos, a qual esteve sempre associada a um significativo aumento do uso de insumos químicos e da mecanização dos cultivos, sem que se procedesse uma análise da eficiência técnica e econômica dos respectivos sistemas de produção utilizados.

The objective of this work, the performance of three varieties of soybean on "Tabuleiros Costeiros" State of Alagoas. The installation of the experiment occurred on March 20, 2006, picking up the parcels on 26 August 2006. The experimental design was a randomized blocks with seven repetitions. The experimental plots consisted of ten rows of 4.0 m in length, spaced 0.50 m. In ten plants per plot were marked certain height of the plant in full bloom stage R2 and point of harvest stage R9 considering the distance between the soil surface and apical end of the main stem, the body weight of 100 seeds, grain production and dry weight in (kg ha(-1)) which are calculated from the production harvested per plot. The soybean plants of three varieties showed height below the minimum required for mechanical harvesting. The three varieties yield or more of the traditionally producing. The average of dry matter accumulation obtained show the variety BRS Tracaja as a good option for the production of forage.

Informations about fertilization and mineral nutrition of the new fusariosis-resistant pineapple cultivars are still scarce, despite the importance of this crop. The purpose of this study was to evaluate the effect of increasing doses of N on fruit yield and quality of the pineapple cultivar 'Vitoria' grown on a 'Humiluvico Espodossolo' in the region of Tabuleiros Costeiros, in the state of Paraiba. The experiment was arranged in a randomized block design, using five N doses (100, 200, 300, 500 and 600 kg ha(-1)N, as urea) applied 60, 180 and 270 days after planting (dap) with three replications. The following variables were evaluated: length and fresh matter of the 'D' leaf; contents of N, P and K in the portions with and without chlorophyll, 300 and 420 dap; average weight, yield, physical properties (fruit weight, length and medium diameter; crown weight and length) and chemical properties (pH, soluble solids -SS, titrable acidity - AT, and the SS/AT ratio) of the fruits at harvest. Increasing N doses linearly increased length and fresh matter of the 'D' leaf and N content and decrease both P and K contents of the chlorophyll portion 300 dap, but did not affect nutrient contents 420 dap; in the chlorophyll-free portion. Increasing N doses, also, led to an increase in K contents 320 dap, but to reductions 420 dap. Individual fruit weight and total yield increased with increasing N doses, as maximum values of 1.0 kg and 37.9 t ha(-1) were estimated at doses of 409.0 and 439.0 kg ha(-1) N, respectively. The N doses did not affect the fruit quality properties, which were compatible with the characteristics described for this cultivar.
