“…The accumulation of macronutrients by banana plants, in general, followed the order K > N > Ca > Mg > P > S, both in the parent plant and in the follower, as well as in the banana mat, except for the productivity class > 45 t ha -1 , in which Mg and P switched positions (Table 5). This result corroborates those obtained by Rodrigues et al (2010), who observed the same sequence of accumulation in the parent plant, when evaluating different doses of Zn supplied through thinned sprouts for the banana cultivar Prata-Anã, under irrigated conditions in northern Minas Gerais. In the different organs and productivity classes, K was the most accumulated macronutrient, followed by N (Table 5), corroborating the results obtained by Neves et al (1991) for the cultivar Pacovan (AAB) and Hoffmann et al (2010) for cultivars of various genotypes.…”

Adequate nutritional management of any plant species requires quantifying the nutrients accumulated in the plant and knowing their allocation in the different organs. The objective of this study was to evaluate the partitioning, accumulation, export of macronutrients and the nutritional efficiency of fertigated Prata banana plants. A historical survey of annual fruit productivity was conducted in 66 plots of Prata banana, selecting four that met the annual productivity classes (< 30.0; 30.0 = 37.5; 37.5 = 45.0 and > 45.0 t ha-1). The dry matter weights of the different organs of parent plant and follower, as well as the respective contents of macronutrients, were used to estimate the accumulation, partitioning, export, sequence of accumulation of macronutrients and nutritional efficiency using the coefficient of biological utilization (CBU). The partitioning of macronutrient accumulation varied with productivity class and plant organ. The average distribution of nutrients in the parent plant and in the follower ranged from 67.5 to 82.8 % and from 17.2 to 32.5 %, respectively. Macronutrient exports per ton of bunch were 4.334, 1.660, 0.361, 0.224, 0.148 and 0.119 kg t-1 for K, N, P, Mg, S and Ca, respectively. Banana mats have a nutrient partitioning pattern for different yields, that is, this work provides evidence that there is an “ideal compartmentalization” that promotes higher productivity; however, more research is needed to support this statement. The most exported nutrients per ton of bunch were K and N. The descending order of accumulation was: K > N > Ca > Mg > P > S. It was observed that the CBUs of N and P were less sensitive to productivity variations, while those of Ca and Mg were the most sensitive.

-The knowledge of the requirements and micronutrients efficiency in banana is relevant to the development of fertilizer recommendations. This study aimed to evaluated requirements and nutritional efficiencies of banana seedlings submitted to omission of micronutrients in nutritive solution. Treatments were complete nutritive solution and solution with individual omission of B, Cu, Fe, Mn and Zn, and two Prata-Anã and BRS Platina hybrid genotypes. Leaf area, dry matter of leaves, rhizome, roots and total and micronutrient contents were determined. With results, the following indexes were calculated: uptake, transport and micronutrient utilization efficiency. B deficiency effected more intensely the growth of both banana genotypes. The nutrient uptake corresponded to the following sequence: Fe > Mn > Zn > B > Cu, which reflects the plant requirements. The BRS Platina hybrid showed higher B, Fe and Zn absorption efficiency in relation to Prata Anã cultivar, which had higher Cu absorption efficiency. BRS Platina hybrid showed higher efficiency in the transport of Fe and Mn, while Prata Anã only for Cu. Prata Anã cultivar showed higher micronutrient utilization efficiency in complete treatment and treatment with omission of micronutrients. Index terms: Musa spp.; mineral nutritional; micronutrient omission; fruit trees. DEFICIÊNCIAS DE MICRONUTRIENTES NO ESTADO
