Irrigation management associated with other banana agricultural practices can provide an increased productivity and improved fruit quality. This study assessed the productive characteristics of banana genotypes under different irrigation water depths. The experiment was conducted at the experimental area of the School of Agronomy (EA/UFG) in Goiânia, GO, Brazil. The experimental design was a split-plot randomized block design, in which four irrigation water depths (30, 65, 100, and 135% of crop potential evapotranspiration, ET pc ) composed the plots and three genotypes ('FHIA 18', 'GrandeNaine', and 'Prata') the subplots, with a spacing of 2.5 × 1.6 m. During the experimental period (first production cycle), the total precipitation was 1719.20 mm. Characterization of genotype development and yield was performed with the following assessments: bunch mass (kg), number of hands, stalk mass (kg), fruit diameter of the second hand (mm), fruit length of the second hand (cm), mass of the second hand (kg), number of fruits of the second hand, total number of fruits, and number of damaged fruits. The cultivar 'FHIA 18', differently from the others, showed a significant response to irrigation water depths on productivity. In the genotypes 'Grande-Naine' and 'Prata', an influence of irrigation was observed only on external and visual characteristics of fruit (diameter, length, and number of damaged fruits). In the genotype 'Prata', the irrigation water depth of 965 mm allowed fruit production with a larger diameter. Fruit length in the genotype 'Prata' increased linearly as water depth increased. The use of irrigation promoted a reduction in the number of damaged fruits in the genotypes 'FHIA 18' and 'Grande-Naine'.

“…Andrade Júnior et al (2012) relatam que a fertirrigação tornase mais eficiente com o aumento da disponibilidade de água no solo, principalmente com relação aos nutrientes com elevada solubilidade, como o potássio. Martins et al (2011) aplicando potássio na dose recomendada (600 kg ha -1 ) via fertirrigação na cultura da banana, constataram uma massa média de cachos de 1500 g durante o primeiro ano de cultivo.…”

-Brazil is one of the largest pineapple producers worldwide, and those fruits are for the juice industry and the in natura market. Its cultivation requires high technology investment by using irrigation and balanced fertilization. However, little is known about the influence of drip irrigation on nutrient uptake by pineapple plants. This study aimed to evaluate the influence of different irrigation depths on nutrients accumulation by 'Pérola' pineapples grown in northern region of Minas Gerais State, Brazil. The experimental design was in randomized blocks with five treatments referring to: 30% of Class A Evaporation Pan (ECA); 50% of ECA; 70% of ECA; 100% of ECA; and 150% of ECA. To determine the levels of macronutrients and dry matter, the plants were separated in root, stem, leaves, 'D' leaf, crown, fruit and whole plant. The sequence of macronutrients accumulated in the whole plant was K>N>Ca>P>Mg. The fruits exported from the cultivated area the following amounts of macronutrients: 17.52 kg ha -1 of K (12.8%); 16.91 kg ha -1 of N (20.7%); 10.77 kg ha -1 of Ca (15.9%), 1.29 kg ha -1 of P (12.4%) and 1.04 kg ha -1 of Mg (20.5%). The irrigation depths that provided the maximum N, P, K and Ca accumulation in the whole plant are 53.6, 61.6, 54.5 and 60.2% of ECA, respectively.

LÂMINAS DE IRRIGAÇÃO E ACÚMULO DE MACRONUTRIENTES NO ABACAXIZEIRO 'PÉROLA' IRRIGADO POR GOTEJAMENTORESUMO -O Brasil é um dos maiores produtores mundiais de abacaxi, cujos frutos se destinam à indústria de sucos e ao mercado in natura. Seu cultivo exige alto investimento tecnológico pelo uso de irrigação e adubação equilibrada; todavia, é pouco conhecida a influência da irrigação por gotejamento no acúmulo de nutrientes por plantas de abacaxi. Assim, este trabalho objetivou avaliar a influência de diferentes lâminas de irrigação no acúmulo de nutrientes pelo abacaxizeiro 'Pérola', cultivado no norte de Minas Gerais. O delineamento utilizado foi em blocos ao acaso, com cinco tratamentos referentes a: 30% da evaporação do tanque Classe A (ECA); 50% da ECA; 70% da ECA; 100% da ECA; 150% da ECA. Para a determinação dos teores de macronutrientes e matéria seca, as plantas foram separadas em: raiz, talo, folhas, folha 'D', coroa, fruto e planta inteira. A sequência de macronutrientes acumulados na planta inteira foi K>N>Ca>P>Mg. Os frutos exportaram da área de cultivo as seguintes quantidades de macronutrientes: 17,52 kg ha -1 de K (12,8 %); 16,91 kg ha -1 de N (20,7 %); 10,77 kg ha -1 de Ca (15.9 %); 1,29 kg ha -1 de P (12,4 %) e 1,04 kg ha -1 de Mg (20,5 %). As lâminas de irrigação que proporcionaram o máximo acúmulo de N, P, K e Ca na planta inteira são de 53,6; 61,6; 54,5 e 60,2% da ECA, respectivamente. (SILVA et al., 2009;GUARÇONI;. VENTURA, 2011).The adequate association between water and nutrients increases crop yield (MARTINS et al., 2011), being that irrigation increases nutrients demand and export. Depending on the soil and irrigation management, the water applie...
