“…Porém, foi inferior ao Brasília com relação ao diâmetro de raiz (Tabela 1). O cultivar Esplanada é caracterizado por produzir raízes compridas e finas, as quais são adequadas para o processamento mínimo visando à produção de cenouretes (Vieira et al, 2005). Independentemente do espaçamento de plantio utilizado, o cultivar Esplanada produziu raízes com maior comprimento e menor diâmetro, quando comparado com as demais.…”

“…Apresenta alta resistência à queimadas-folhas e baixa incidência de ombro verde. É recomendado para o plantio em sistemas de produção convencional e orgânico no verão, nas principais regiões produtoras de cenoura no Brasil (Vieira et al, 2005). Machado et al (2003), avaliando a influência do espaçamento na quantidade de açúcares e sólidos solú-veis totais em cenoura, utilizando as densidades de plantio de 14, 16, 18 e 20 plantas por metro de fileira, verificaram que a concentração de açúcares totais variou entre 3,2 e 3,6% para o cultivar Nantes e de 3,5 a 3,9% para o Alvorada.…”

Quality of carrot roots under different population densitiesThis work was carried out from July to September, 2006, at the vegetable garden of UFERSA, in Mossoró, RN, Brazil, to evaluate the effect of different plant spacing on root quality of three cultivars of carrot. The experimental design was a complete randomized blocks, in a 6x3 factorial scheme, with three replications. The studied factors were spacing (20x4, 20x6, 20x8, 15x4, 15x6, and 15x8 cm) and cultivars (Brasília, Alvorada and Esplanada). The evaluated carrot root characteristics were: root length, root diameter, xylem length, xylem diameter, soluble solids content (SS), total sugar content (TS), total acidity, vitamin C, SS/TS ratio, and pH. The factors cultivar and plant spacing did not show interaction for any evaluated characteristic. Plant spacing influenced length and diameter of both root and xylem. Cultivar Alvorada had better performance for soluble solids and total sugar, as well as for SS/TS ratio.

“…The characteristics evaluated in the carrots were: dry mass of shoots and roots (obtained from a sample of twelve plants from the harvest area of the plot, where the dry mass was determined by heating in an oven with forced air circulation at 65 ° C until constant weight and expressed in t ha -1 ); total root productivity (obtained from the fresh weight of plant roots of the harvest area, and expressed in t ha -1 ); commercial productivity (obtained from the fresh weight of the plant roots of the harvest area free of cracks, bifurcations, nematodes and mechanical damage, expressed in t ha -1 ) and the classified productivity of the roots (assessed according to the greatest length and largest diameter), in the classes: long (with a length of 17 to 25 cm and diameter smaller than 5 cm), medium (with a length of 12 to 17 cm and a diameter greater than 2.5 cm), short (with a length of 5 to 12 cm and a diameter larger than 1 cm) and scrap (roots falling outside the other measurement categories), as per VIEIRA et al (2005).…”

-The objective of this study was to evaluate the agronomic efficiency of intercropping combinations of carrot and arugula at different population densities in bicropping in the semi-arid conditions of the Brazilian Northeast. The study was conducted at the "Rafael Fernandes" Experimental Farm of the Universidade Federal Rural do Semi-Árido (UFERSA) during the period September 2011 to February 2012. The experimental design was of randomized complete blocks with treatments arranged in a 4 x 4 factorial scheme with four replications. The combinations were four population densities of carrot (40, 60, 80 and 100% of the recommended population in sole crop -RPSC) with four population densities of arugula (40, 60, 80 and 100% of the RPSC). The recommended population densities for sole crops of carrot and arugula are 500,000 and 1,000,000 plants per hectare, respectively. All treatments were fertilized with hairy woodrose (Merremia aegyptia L.), a spontaneous species of the Caatinga biome. The highest agronomic efficiency of carrot intercropped with arugula in bicropping was achieved in the combination of 40% of RPSC for the carrot and 100% of RPSC for the arugula. The commercial maximum yield (33.74 t ha -1 ) of carrot roots and the maximum yields of arugula green mass (8.06 and 2.67 t ha -1 ) in both cultivations were also obtained in the combination of population densities of 40% of RPSC for carrot and 100% of RPSC for arugula.

“…This result for -Esplanada‖ is due to the peculiar characteristic of this cultivar, which tends to produce longer and thinner roots, suitable for the minimum processing aiming at the production of cenourete (VIEIRA et al, 2005). Teófilo et al (2009) state that the plant initially intended photoassimilates produced to the formation of structures of the aerial part aiming to increase the leaf area until a certain period, since the tendency is that most of the photoassimilates produced are destined to the structures of reserves (drains), which in the case of carrot is the root.…”

-The objective of this research was to evaluate combinations of cultivars of coriander and arugula in two croppings with cultivars of carrot in a strip-intercropping system. The study was conducted from November 2014 to March 2015. The experimental design was a randomized complete block in a 2 x 2 x 2 + 2 factorial scheme, with four replications. The treatments consisted of the combination of two cultivars of coriander (Verdão and Português) with two cultivars of carrot (Brasília and Esplanada) and two cultivars of arugula (Cultivada and Folha Larga) in a strip-intercropping system plus two additional treatments, where the first represents the cultivars in monocropping and the second the cultivation types (monocropping and intercropping). The characteristics evaluated in the coriander and arugula were green mass yield and shoot dry mass. The following were evaluated in carrot: shoot dry mass, dry mass of roots, total and commercial productivity, and classified productivity of roots. In the intercropping system, the agronomic indices of land equivalent ratio, productive efficiency index, and score of the canonical variable were evaluated. The economic efficiency indicators determined were gross and net income, rate of return, profit margin, monetary advantage, and modified monetary advantage. There was no significant interaction among the cultivars of coriander, carrot, and arugula for coriander and arugula green mass yields, and for total and commercial productivities of carrot roots. The best polyculture was of that involved in the cultivars -Português,‖ -Esplanada,‖ and -Cultivada‖. POLICULTIVOS DE COENTRO, CENOURA E RÚCULA EM CONSÓRCIO EM FAIXASRESUMO -O objetivo desta pesquisa foi avaliar combinações de cultivares de coentro e rúcula em bicultivo com cultivares de cenoura em sistema consorciado de faixas. O estudo foi desenvolvido de novembro de 2014 a março de 2015. O delineamento experimental utilizado foi o de blocos ao acaso, em esquema fatorial 2 x 2 x 2 + 2, com quatro repetições. Os tratamentos consistiram da combinação de duas cultivares de coentro (Verdão e Português), com duas cultivares de cenoura (Brasília e Esplanada) e duas cultivares de rúcula (Cultivada e Folha Larga) em sistema de consórcio em faixas, mais dois tratamentos adicionais, onde o primeiro representa as cultivares em monocultivo e o segundo os tipos de cultivo (monocultivo e consórcio). As características avaliadas no coentro e na rúcula foram: rendimento de massa verde e massa seca da parte aérea. Na cenoura foram avaliados: massa seca da parte aérea, massa seca de raízes, produtividade total e comercial e produtividade classificada de raízes. No sistema de consórcio, foram avaliados os índices agronômicos: índice de uso eficiente de terra, índice de eficiência produtiva e pontuação da variável canônica. Os indicadores de eficiência econômica determinados foram: lucro bruto e líquido, taxa de retorno, margem de lucro, vantagem monetária e vantagem monetária corrigida. Não houve interação significativa entre as cultivare...
