Crescimento e acúmulo de macronutrientes na cultura da cebola em Baraúna (RN) e Petrolina (PE)

Abstract: Com o objetivo de avaliar o crescimento e o acúmulo de nutrientes por cultivares de cebola experimentos foram desenvolvidos na estação experimental de Bebedouro (Petrolina, PE) pertencente à Embrapa Semiárido, no período de maio a outubro de 2009 e em Baraúna, RN, em área comercial, no período de junho a outubro de 2009. O delineamento utilizado em cada experimento foi em blocos casualizados completos, com quatro repetições em esquema fatorial 2 x 6. Os tratamentos resultaram da combinação de duas cultivares d… Show more

“…For the micronutrients, the maximum extracted amounts were 271, 72, 2760, 84, and 296 g ha -1 for B, Cu, Fe, Mn, and Zn, respectively. The amounts of macronutrients accumulated were higher than those found by Vidigal, Moreira and Pereira (2010), Aguiar Neto et al (2014), and Kurtz et al (2016), except for P, which was similar to that found in this experiment. The amount of nutrients extracted by the onion plant varies with the obtained yield and with the genetic material cultivated.…”

“…According to studies by Aguiar Neto et al (2014), the order of nutrient accumulation by the onion was different between cultivars Texas Grano 502 and IPA 11 and in relation to the cultivation site (Petrolina-PE and Baraúna-RN). Of the total nutrients absorbed by the Alfa Tropical onion plant cultivated via seedling transplant, the bulbs accumulated 50.35% nitrogen (N), 83.98% (phosphorus) (P), 53.34% potassium (K), 45.09% calcium (Ca), 60.00% magnesium (Mg), 56.17% sulfur (S), 84.32% zinc (Zn), 46.89% iron (Fe), 41.01% manganese (Mn), and 9.77% copper (Cu) (VIDIGAL; PEREIRA; PACHECO, 2010).…”

“…Bulb diameter is directly related to the amount of water applied (Kumar et al, 2007;Martin de Santa Olalla, Juan Valero, & Fabeiro Cortés, 1994). At 100 DAT, the BDB values obtained for different irrigation depths were similar to those found by Neto et al (2014) (4 g) for the cultivar Texas Grano 502 and were lower than those of the cultivar IPA 11 (12.5 g).…”

“…O solo é classificado como cambissolo eutrófico com fertilidade média a alta, textura argilosa, moderadamente drenado e com relevo plano (GUERRA et al, 2014). Apresenta temperatura média anual variando entre 36,0; 27,4 e 21,0 ºC para máxima, média e mínima, respectivamente, precipitação pluviométrica média anual de 673 mm, concentrados principalmente em uma única estação, de fevereiro a maio, com ocorrência de períodos agudos de estiagem (AGUIAR NETO et al, 2014). Para delimitação das parcelas foi utilizada uma fita métrica, dentro das quais registrou-se a altura dos indivíduos (plantas) com altura total maior ou igual a 1 m.…”
