Resumo: | Banana is a crop of major importance for the Brazilian semiarid region. However, because of the low availability and irregularities of the rainfall in this area, it is necessary to combine techniques that allow a higher water-use efficiency. This study aimed to evaluate the influence of different combinations of irrigation depths and planting densities on the precocity, yield and water-use efficiency of BRS Platina banana plants, in the semiarid region of the Bahia state, Brazil. A randomized block design with four replicates was used, in a split-plot arrangement. Irrigation depths of 55 %, 70 %, 85 % and 100 % of the crop evapotranspiration (ETc) were assigned to the plot, and the planting densities of 1,600 plants ha-1, 2,000 plants ha-1, 2,666 plants ha-1 and 3,333 plants ha-1 to the split-plot. The hands weight and number of fruits decreased in a linear way with the increase in the planting density (1,600 plants ha-1 to 3,333 plants ha-1) from 10.89 kg to 9.49 kg and from 97.16 to 89.86, respectively; whereas the hands yield (15.5 t ha-1 to 25.79 t ha-1) and the harvest period (442 to 455 days) increased. The number of fruits increased linearly from 89.46 to 98.08 with the irrigation depth of 55 % to 100 % of the ETc. The yield and water-use efficiency increased linearly as the planting density increased (1,600 plants ha-1 to 3,333 plants ha-1) from 5.14 to 8.60, while the water-use efficiency decreased with the irrigation depth from 7.97 to 5.50, conidering 55 % to 100 % of the ETc. It is possible to obtain higher yields and a higher water-use efficiency by using a higher planting density and irrigation levels below 100 % of the ETc.

No entanto, devido à baixa disponibilidade e irregularidades de chuvas nesta região, torna-se necessário o uso de uma combinação de técnicas que permitam maior eficiência no uso de água. Objetivou-se avaliar a influência de combinações de lâminas de irrigação e densidades de plantio na precocidade, produtividade e eficiência de uso de água em bananeira BRS Platina, no semiárido do estado da Bahia. O delineamento experimental foi em blocos casualizados, com quatro repetições, distribuídas em parcelas subdivididas. Lâminas de irrigação de 55 %, 70 %, 85 % e 100 % da evapotranspiração da cultura (ETc) foram atribuídas à parcela, e densidades de plantio de 1.600 plantas ha-1, 2.000 plantas ha-1, 2.666 plantas ha-1 e 3.333 plantas ha-1 à subparcela. O peso das pencas e o número de frutos diminuíram de forma linear com o aumento da densidade de plantio (1.600 plantas ha-1 para 3.333 plantas ha-1), passando de 10,89 kg para 9,49 kg e de 97,16 para 89,86, respectivamente, enquanto a produtividade de pencas (15,5 t ha-1 para 25,79 t ha-1) e o período para colheita (442 para 455) aumentaram. O número de frutos aumentou linearmente de 89,46 para 98,08 com a lâmina de irrigação de 55 % para 100 % da ETc. O rendimento e a eficiência do uso de água aumentaram linearmente à medida em que a densidade de plantio (1.600 plantas ha-1 para 3.333 plantas ha-1) aumentou, passando de 5,14 para 8,60, e a eficiência do uso de água mostrou redução com a lâmina de irrigação, passando de 7,97 para 5,50, considerando-se 55 % a 100 % da ETc. É possível obter maiores rendimentos e maior eficiência no uso de água utilizando-se maior densidade de plantio e nível de irrigação abaixo de 100 % da ETc.
