“…The titratable acidity responded in a similar way and the mean values varied from 0.73 to 0.89%; thus, they are within the range of 0.75 to 1.15%, set by Manica (2000). This variation of pH, associated with the values of soluble solids and acidity, indicates that the harvest was performed at the right season as these variables are associated with the ripening of the fruits (Souza et al, 2013).…”

“…Sugar content, expressed by the percentage of total soluble solids (TSS) or ºBrix, is a very important variable to determine the fruit quality. This variable is usually used as a maturity index for some fruits and indicates the amount of substances found dissolved in the juice; also, ºBrix increases as the sugars accumulate in the fruit (SOUZA et al, 2013;SILVA et al, 2011). Therefore, the values found in this study, for fruit quality, indicate potential for pineapple production, especially for fruits meant to be eaten fresh; although, further research must be done so as to increase yields of pineapple and to make viable the cultivation of pineapple in semi-arid regions.…”

We aimed to evaluate the effects of different irrigation depths with saline water on growth, yield, water-use efficiency, and fruit quality of ‘Pérola’ pineapple plant grown in the semi-arid of Bahia state. The experiment was carried out in a randomized block design with five treatments which represented the irrigation depths: 100% of crop evapotranspiration (ETc) with irrigation water of 0.75 dS m-1 in electrical conductivity (ECiw); and 50, 75,100, and 125% of ETc with water of 3.6 dS m-1 in ECiw. Pineapples were grown under field conditions watered by drip irrigation in which pressure compensating emitters had 8 L h-1 flow rate. We observed that the irrigation depth 100% of ETc with water of 0.75 and 3.6 dS m-1 in ECiw provides higher pineapple yields under the semi-arid conditions of this study, and the chemical quality of the fruits are up to commercial standards, except when applying 125% of ETc with water of 3.6 dS m-1 in ECiw.

“…Na Tabela 4 se acham os valores médios dos coeficientes de cultura para cada mês de duração do ciclo da cultura; nota-se que no décimo segundo mês (outubro), maior valor de Kc (1,13) se deve à fase de enchimento do fruto e maturação. Souza et al (2012) Na Figura 4 são apresentados coeficientes de cultura para o abacaxizeiro irrigado com tubulação superficial e tubulação enterrada sendo que os Kcs para o abacaxizeiro sob tubulação enterrada apresentaram menores valores em razão, possivelmente, da menor perda de água ocorrida. Na tubulação superficial foram verificados valores médios de Kc entre 0,5 a 1,1, e para a tubulação enterrada valores médios de Kc compreendidos entre 0,4 a 0,95. lIteratura cItada…”

RESUMODentre as culturas irrigadas o abacaxi vem-se destacando por sua importância econômica e social. É uma cultura exigente em tratos culturais dentre os quais a irrigação exerce forte influência na produção e qualidade dos frutos. O objetivo deste trabalho foi determinar os valores dos coeficientes de cultura e evapotranspiração do abacaxizeiro irrigado e cultivado em Uberaba, MG. O experimento foi conduzido no setor de Fruticultura do IFTM, campus Uberaba, MG. A cultivar utilizada foi a Smooth Cayenne. A irrigação foi realizada por tubogotejadores de duas formas: enterrados e superficiais. Para estimativa da evapotranspiração de referência (ETo) foi utilizada a equação de Penman-Monteith e para obtenção da evapotranspiração da cultura (ETc) o balanço de água no solo. Dentre os resultados verifica-se que o maior valor de evapotranspiração da cultura foi de aproximadamente 6,8 mm; os valores de ETc médios encontrados quando a irrigação foi efetuada com tubogotejadores enterrados e superficiais foram, respectivamente, de 2,88 e 3,37 mm; os valores médios de coeficientes de cultura foram de 0,97 (tubogotejador enterrado) e 0,91 (tubogotejador superficial) para todo o ciclo do abacaxi.

It is a crop demanding in cultural practices, among which irrigation exercises strong influence upon the production and quality of fruits.The purpose of this study was to determine the values of the crop coefficients and evapotranspiration of the pineapple crop in Uberaba, MG. The experiment was conducted in the Fruit Crops Sector of "Instituto Federal de Educação, Ciência e Tecnologia do Triângulo Mineiro, campus Uberaba", MG. The cultivar used was Smooth Cayenne. Irrigation was carried out through driplines in two manners: buried and surface. For the estimate of the reference evapotranspiration (ETo), the Penman-Monteith equation was utilized and for obtaining the crop evapotranspiration (ETc), the soil water balance was used. Among the results, the highest value of evapotranspiration of the crop was about 6.8 mm; the values of mean ETc found when irrigation was performed with buried and surface driplines were respectively of 2.88 and 3.37 mm and when the irrigation was performed with surface and buried piping, respectively; the mean values of crop coefficient were of 0.97 (driplines buried) and 0.91 (driplines surface) for the entire cycle of the pineapple crop.
