“…Banana yield tends to increase with the transpiration (Coelho et al, 2006), while monthly rainfall between 100 and 180 mm allows economically viable harvests (Costa et al, 2009). The values of 717 mm of rainfall and 2,438 mm of reference evapotranspiration are the most adequate for the production of banana in northern Minas Gerais (Borges et al, 2011).…”

A B S T R A C TThis study aimed to analyze different irrigation strategies in two cultivars of the banana crop. The study was conducted in four production cycles of 'Prata-Anã' and 'BRS Platina' bananas. The applied irrigation depths (ID) were obtained by the model ID = K x LA x ETo, where K is an empirical transpiration constant of 0.20; 0.35; 0.50 and 0.65 for the strategies 1, 2, 3 and 4, respectively; LA is the leaf area of mother and daughter plants of 'Prata-Anã' and ETo is the reference evapotranspiration. The strategy 5 was obtained according to the crop evapotranspiration, ETc = ETo x Kc, where Kc is the crop coefficient. Drip irrigation system was used, with two laterals per plant row and emitters with flow rate of 8 L h -1 , spaced at 0.50 m. It was found that 'Prata-Anã' is more efficient than 'BRS Platina' in terms of water use and the model for irrigation management, ID = 0.35 x LA x ETo, is recommended to optimize water use by 'Prata-Anã' and 'BRS Platina' bananas, with increase in water use efficiency and maintenance of yield. The same model, with K coefficient equal to 0.50, makes it possible to obtain yield and water use efficiency equal to those obtained with irrigation management based on the ETc. Estratégias de manejo de irrigação para bananeira tipo Prata R E S U M OObjetivou-se, com o presente estudo, avaliar diferentes estratégias de irrigação para bananeiras 'Prata-Anã' e 'BRS Platina' em quatro ciclos produtivos. As lâminas de irrigação aplicadas (LA) foram obtidas pelo modelo LA = K x AF x ETo em que K é a constante empírica de transpiração de 0,20; 0,35; 0,50 e 0,65 para as estratégias 1, 2, 3 e 4, respectivamente; AF, área foliar das plantas mãe e filha da 'Prata-Anã' e ETo, evapotranspiração de referência. A estratégia 5 foi obtida conforme a evapotranspiração da cultura, ETc = ETo x Kc, sendo Kc seu coeficiente. Utilizou-se o sistema de irrigação por gotejamento com duas laterais por fileira de planta, com emissores de 8 L h -1 espaçados 0,50 m totalizando 10 gotejadores por planta. Verificou-se que a 'Prata-Anã' é mais eficiente no uso da água cujo modelo para manejo de irrigação, LA = 0,35 x AF x ETo é indicado para otimizar o uso da água em bananeiras 'Prata-Anã' e 'BRS Platina' com aumento da eficiência de uso da água e manutenção da produtividade. O mesmo modelo possibilita com a constante K igual a 0,50, a obtenção de produtividades e de eficiência de uso da água iguais às obtidas com manejo de irrigação com base na ETc.

“…Visando à obtenção de colheitas economicamente rentáveis, considera-se suficiente uma precipitação mensal entre 100 e 180 mm mês -1 (Costa et al, 2009). O crescimento e o rendimento da cultura são afetados pelo déficit hídrico (Doorenbos & Kassam, 1994).…”

RESUMOAvaliou-se, com o presente trabalho, a influência de diferentes lâminas de irrigação sob o crescimento da cultura da bananeira Grande Naine. O experimento foi conduzido no campo experimental do Centro Nacional de Pesquisa Mandioca e Fruticultura. Utilizou-se delineamento experimental blocos casualizados com seis lâminas de irrigação e oito repetições. A lâmina de irrigação L1 correspondeu à chuva. A lâmina L6 foi determinada com o uso do Kc e ETo. As demais lâminas foram determinadas pela fórmula NH = K x AF x ETo, em que NH é a necessidade hídrica da cultura (L planta -1 ), K (coeficiente empírico de transpiração da planta) e AF -área foliar (m 2 planta -1 ) e ETo -evapotranspiração de referência (mm). Foram avaliados: altura da planta; circunferência do pseudocaule; área foliar; número de folhas vivas e duração do ciclo da cultura. O melhor crescimento da cultura foi obtido com o coeficiente de transpiração de 0,57 e uma lâmina de irrigação estimada em 1247 mm. Palavras-chave: Musa spp., manejo de água, transpiraçãoGrowth of banana Grande Naine under different irrigation levels in Coastal Plain ABSTRACT This study evaluated the influence of different irrigation levels on the growth of the banana crop cv. Grande Naine. The experiment was conducted in the experimental field of the Centro Nacional de Pesquisa Mandioca e Fruticultura. A randomized block design was used with six levels of irrigation and eight replications. The irrigation L1 corresponded to rain. The irrigation L6 was determined using the Kc and ETo. The other irrigation levels were determined by the formula NH = K x AF x ETo, where NH is the water requirement of the crop (L plant -1 ), K (empirical coefficient of plant transpiration), AF -leaf area (m 2 plant -1 ) and ETo -reference evapotranspiration (mm). The parameters evaluated were: plant height, pseudostem circumference, leaf area, alive leaf number and duration of the crop cycle. The growth of cv. Grande Naine was influenced by irrigation, it is possible to estimate the water requirement of the banana crop, based on knowledge of leaf area and ETo. The best crop growth was obtained with a transpiration coefficient of 0.57 and irrigation depth estimated in 1247 mm.

“…Thus, the knowledge on the maximum daily and total annual water requirements of a given culture allows estimating the total volume of water that should be applied to meet the water needs (FREITAS; RA-MOS; COSTA, 2008). Since water supplied through irrigation promotes optimal plant development, increases productivity and allows obtaining production in a continuous and uniform way, as well as good fruit quality (COSTA et al, 2009). Figure 2b shows that nitrogen fertilization level equivalent to 178 kg ha -1 provided higher crop production, yielding 454 fruits per guava plant.…”

-The objective of this study was to evaluate the effects of different water depths and nitrogen fertilization levels applied by fertigation on the physical attributes of guava fruits cv. Paluma. The study was carried out taking into account factors water depths (1144, 1465, 1785 and 2106 mm) and nitrogen fertilization levels (50, 100, 150 and 200 kg ha -1 ). The water depths 1730 and 1750 mm increased production and the average weight of guava fruit in, respectively, 25.1 and 31.6%. The applications 178 and 152 kg N ha -1 increased at 67.1% in the production of fruits and 16.3% the average fruit weight. The combined application of 150 kg N ha -1 and 1789 mm of water amounted to 63.3% of the total weight of fruit. The equatorial diameter of the fruit was influenced by individual water depths applied evidencing an increase of up to 26.8%. Already combinations 200 kg N ha -1 and 1746 mm of water increased the longitudinal diameter of the fruits by 18.77%. The application of water depth to 1144 mm, associated with 143 kg N ha -1 gave index of the most satisfactory way to guava fruit. Keywords
