Resumo: Chemical analyses of nutrient contents in leaves is possible to indicate the plant nutritional state, where the results is compared with a standard. For results interpretation it is necessary the establishment standard values that are based on correlation studies between nutrient concentration in the leaves and crop development or yield. The objective of this work was to establish critical levels of macro and micronutrients in banana leaves, cultivar Pacovan, grown under irrigation in the Petrolina-PE/Juazeiro-BA region. In selected banana orchards 20 plants were chosen for further evaluations. Leaf sample were collected at flowering for chemical analyses and bunch weight determined. Evaluations were carried out during two production cycles. Descriptive statistical analysis was performed considering four extracts of bunch weight (< 10; > 10 and < 15; > 15 and < 20; > 20 kg), and plants that produced bunch 20 kg heavier express an ideal nutritional conditions. The nutrient levels determined for the banana cultivar Pacovan, grown under irrigation, in the Petrolina-Juazeiro region, were the following: 22-24 g of N/kg; 1,71,9 g of P/kg; 25-28 g of K/kg; 6,3-7,3 g of Ca/kg; 3,1-3,5 g of Mg/kg; 1,7-1,9 g of S/kg; 13-16 mg of B/kg; 6-7 mg of Cu/kg; 71-86 mg of Fe/kg; 315-398 mg of Mn/kg; and 12-14 mg of Zn/kg.

The nutrient levels determined for the banana cultivar Pacovan, grown under irrigation, in the Petrolina-Juazeiro region, were the following: 22-24 g of N/kg; 1,71,9 g of P/kg; 25-28 g of K/kg; 6,3-7,3 g of Ca/kg; 3,1-3,5 g of Mg/kg; 1,7-1,9 g of S/kg; 13-16 mg of B/kg; 6-7 mg of Cu/kg; 71-86 mg of Fe/kg; 315-398 mg of Mn/kg; and 12-14 mg of Zn/kg.Por meio da análise química dos nutrientes na folha, é possível avaliar o estado nutricional da planta, em que os resultados obtidos são comparados a padrões que se baseiam na correlação entre a concentração do nutriente nas folhas e o desenvolvimento ou produção da cultura. Objetivou-se definir os teores padrões de macro e micronutrientes nas folhas de bananeiras cv. Pacovan sob irrigação, no pólo Petrolina-PE/Juazeiro-BA. Nos bananais selecionados, foram marcadas 20 bananeiras e amostradas as folhas na época do florescimento, para análise química, e anotado o peso dos cachos de dois ciclos de produção subseqüentes. Realizou-se a análise estatística descritiva, com os dados de plantas com pesos de cachos em quatro estratos (< 10; > 10 e < 15; > 15 e < 20; > 20 kg), considerando os cachos superiores a 20 kg como em condições ideais de nutrição. As faixas dos teores padrões definidas para cv. Pacovan, sob irrigação, no Distrito de Irrigação Senador Nilo Coelho, em Petrolina-PE, foram: 22-24 g de N/kg; 1,7-1,9 g de P/kg; 25-28 g de K/kg; 6,3-7,3 g de Ca/kg; 3,13,5 g de Mg/kg; 1,7-1,9 g de S/kg; 13-16 mg de B/kg; 6-7 mg de Cu/kg; 71-86 mg de Fe/kg; 315-398 mg de Mn/kg; e 12-14 mg de Zn/kg.Editora da Universidade Federal de Lavras2004-10-012015-04-30T13:33:15Z2015-04-30T13:33:15Z2015-04-30info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articletext/htmlhttp://www.scielo.br/scielo.php?script=sci_arttext&pid=S1413-70542004000500018BORGES, A.
