“…The results of this experiment exceeded those of Costa et al (2012), in which leaf area at flowering for Galil-18 (FHIA-18) cultivar ranged from 9.29 to 12.26 m 2 , being significantly influenced by irrigation depths in Cruz das Almas-BA.…”

-This assay was conducted in the experimental area of the Federal Institute of Bahia, Campus Guanambi, BA, and aimed to evaluate agronomic traits of Prata, Cavendish, Gros Michel and Maçã banana cultivars three production cycles. The 72 treatments, 24 cultivars and three production cycles were arranged in a split plot scheme in time, in a completely randomized design with five replications and four plants per plot. Plots were arranged in 24 cultivars, Prata-Anã, Maravilha, FHIA-18, FHIA-18 BRS, BRS Platina, JV42-135, Pacovan, Japira, PV79-34, Pacovan-Ken, Preciosa, Guarantida, Maçã, Caipira, BRS Tropical, BRS Princesa, YB42-03, YB42-07, YB42-47, Grande-Naine, Calypso, Buccaneiro, FHIA-23 and FHIA-17; and subplots consisted of three production cycles. Data obtained were submitted to analysis of variance. The average of the cultivars were grouped by Scott-Knott criterion (p<0.05) and production cycles compared by Tukey test (p<0.05). 'JV42-235', 'Japira' and 'Pacovan-Ken' cultivars had larger size and 'Grande Naine' had smaller size. 'Prata-Anã' cultivar had higher number of leaves at harvest, with leaf area index similar to the others. 'BRS Platina' cultivar is earlier at flowering and harvest. 'Maravilha', 'BRS Platina', 'FHIA-23', 'BRS Tropical and BRS Princesa' cultivars presented greater potential for use by farmers.

“…Irrigation water depth did not influence leaf area and yield because the range of irrigation water depths from 0.70 to 1.30 ETc corresponded to the one in which the yield rate begins to decrease as irrigation depth increases. Larger yield rate reduction occurred for irrigation water depths in between 1.0 and 1.25 ETc, as observed in studies that evaluated banana yield as a function of irrigation depths (Costa et al, 2014;Coelho et al, 2006;Figueiredo et al, 2006). In addition, the noneffect of the irrigation water depth on leaf area and yield may be due to the range of irrigation water depths close to or higher than 0.85 ETc, considering cycles 2 and 3.…”

The use of different water depths and soil surface soil surface wetted areas by micro-sprinkler irrigation systems results different wetted soil volumes and evapotranspiration conditions, which may cause changes in fruit production quality and quantity. The objective of this study was to evaluate yield, fruit physical characteristics and leaf area of banana cv. Grand Naine under different irrigation depths and soil surface wetted areas in Northern Minas Gerais State, Brazil. The experiment was conducted in the period 2003 to 2006, involving three production cycles of 'Grand Naine' banana with planting spacing of 3.0 m × 2.7 m irrigated by micro-sprinklers. The experimental design was a randomized block with four replicates in a split-plot arrangement with three soil surface wetted areas in the plot and five irrigation depths as subplots. The irrigation levels were taken as fractions of crop evapotranspiration (ETc): 0.70; 0.85; 1.00; 1.15 and 1.30 ETc, and the soil surface wetted areas (Wa) were: Wa 1 of 10.17 m 2 , with emitter of 20 L h-1 and radius of throw of 1.8 m; Wa 2 of 23.74 m 2 , with emitter of 63.6 L h-1 and radius of throw of 2.7 m and Wa 3 of 28.26 m 2 , with emitter of 60 L h-1 and radius of throw of 3.0 m. Central fruit diameter and mean weight, leaf area and yield of 'Grand Naine' banana were not influenced by irrigation depths. On the other hand, smaller soil surface wetted area causes reduction in central fruit length and weight, leaf area and yield of 'Grand Naine' banana.

“…Diversos autores têm analisado as relações hídricas da bananeira do grupo Prata (Coelho et al, 2006;Figueiredo et al, 2006;Braga Filho et al, 2008;Costa et al, 2012); porém, há poucos estudos sobre cultivares de plátanos sob irrigação (Goenaga et al, 1995;Faria et al, 2010), e a maioria não avalia o efeito de diferentes lâminas de irrigação no crescimento ou na produção da cultura. O crescimento de áreas plantadas com essa bananeira, associado às constantes incertezas climáticas ou à distribuição irregular de chuvas, tem aumentado o número de usuários da irrigação, o que demanda conhecimento das reais necessidades hídricas da cultura.…”

Resumo -O objetivo deste trabalho foi avaliar os efeitos de diferentes lâminas de água nas variáveis morfofisiológicas e de produção de três cultivares de bananeira do tipo Terra. Utilizou-se o delineamento experimental de blocos ao acaso, em arranjo fatorial com 12 tratamentos e três repetições. Os tratamentos consistiram de lâminas de água correspondentes a 33, 66, 99 e 120% da evapotranspiração da cultura (ETc), além do controle sem irrigação, e das cultivares Terra Maranhão, Terrinha e D'Angola. Avaliaram-se as variáveis morfofisiológicas: altura de planta, diâmetro do pseudocaule, área foliar, condutância estomática e, na colheita, número de dedos e de pencas, e peso de pencas por cacho. Os coeficientes de cultura das cultivares de bananeira tipo Terra foram obtidos a partir da melhor combinação de produtividade e eficiência de uso de água. As lâminas de água de uso consuntivo de 1.599 mm (1,20 da ETc), 922 mm (0,84 da ETc) e 940 mm (1,06 da ETc) correspondem às máximas produtividades e eficiências de uso de água das cultivares Terra Maranhão, Terrinha e D'Angola, respectivamente.Termos para indexação: Musa, banana tipo Terra, coeficiente de cultura, condutância estomática, plátano, produção. Water requirements of Terra-type banana under coastal tableland conditionsAbstract -The objective of this work was to evaluate the effects of different water depths on the morphophysiological and yield variables of three Terra-type banana cultivars. A randomized complete block design was used, in a factorial arrangement with 12 treatments and three replicates. Treatments consisted of water depths correspondent to 33, 66, 99, and 120% of crop evapotranspiration (ETc), besides the control without irrigation, and of the cultivars Terra Maranhão, Terrinha, and D'Angola. The morphophysiological variables evaluated were: plant height, pseudostem diameter, leaf area, stomatal conductance, and, during harvest, the number of fingers and hands, and hand weight per bunch. Crop coefficients of the Terra-type banana cultivars were obtained from the best combination of yield and water use efficiency. The consumptive water-use depths of 1,599 mm (1.20 ETc), 922 mm (0.84 ETc), and 940 mm (1.06 ETc) correspond to the maximum yields and water use efficiencies of the cultivars Terra Maranhão, Terrinha, and D'Angola, respectively.
