“…Coelho et al (2001) observed the occurrence of greater concentrations of fine roots of the same cultivar in an irrigated experiment, in Piauí, Brazil, until 1.5 m of depth for horizontal distances from the trunk up to 3m, following an asymmetry in function to the irrigation system position disposed for 7 years. Silva et al (2001) found in Petrolina, Pernambuco, Brazil, for the same cultivar that was 7 years old and cultivated with irrigation and spacing of 5 x 8m, the presence of approximately 80% of the roots around 1.4 m of depth, with a homogeneous distribution through the soil profile, but with an effective depth that reached 1.8m.…”

“…This is alarming, since the crop is not irrigated, because the productivity of mango is significantly reduced when exposed to non-irrigated condition (SANTOS et al, 2014), or when it is irrigated with poor water levels (CAMPOS et al, 2008), indicating that to cultivate mango it is recommended that the water supply is enough to attend to the culture evapotranspiration (SANTOS et al, 2014). Results obtained by Coelho et al (2002) showed that thirty days without irrigation in the fruit growth phase were enough to reduce the fruit size in 20%, comparing to the irrigated crops.…”

“…The supply of water during the reproductive phase of mango promotes the occurrence of bigger fruits due to the supply of water in the soil (COELHO et al, 2002;SCHULZE et al, 2013), on the other hand, the occurrence of rains during the flowering period may contribute to the reduction of the production due to the unfavorable effect of moisture in pollination (SIMÃO, 2004). Silva et al (2009) obtained significant gains in productivity of mango when they increased the water supply through irrigation, varying from 29.49 to 31.06 t ha -1 , corresponding to the reference evapotranspiration (ETo) levels of 70% and 90%, respectively.…”

“…We identified the presence of roots through the soil profile sampled for chemical and physical analysis (0 until 0.80 m of depth). Some studies suggest an effective depth of the mango root system, Tommy Atkins, ranging between 0.60 and 0.90 m (COELHO et al, 2001), between 0.20 and 0.90 m (SANTOS et al, 2014) and in some cases reaching 1.4 m of depth (SILVA et al, 2001), depending on the characteristics as soil type and management adopted, and despite that we did not measured the effective depth in the experiment, the presence of roots until 0.80 m suggests all this soil volume as a moisture source for the orchard.…”

-The aim of this study was to estimate the water consumption in mango orchard during its phenological stages in the northeastern of the State of Pará, Brazil. For this purpose, it was installed and instrumented a micrometeorological tower in a mango orchard, cv. Tommy Atkins, of 22 years old, with data collected during the crops of 2010/2011 and of 2011/2012. The actual crop evapotranspiration was estimated from the energy balance using the Bowen ratio technique. The crops were subjected to different weather conditions, consequently, some differences in the Bowen ration values were observed. The evapotranspiration suffered influences of meteorological conditions during the period. The actual crop evapotranspiration during its reproductive period ranged between 402.9 and 420 mm with a mean daily water consumption of 3.8 mm at flowering, of 4.25 mm at fruit fall, of 3.56 mm at fruit formation, of 3.0 mm at fruit maturation and of 3.73 mm for the whole period. Index terms: Mangifera indica L, Tommy Atkins, evapotranspiration, bowen ratio. ESTIMATIVA DO CONSUMO HÍDRICO NO PERÍODO REPRODUTIVO EM POMAR DE MANGUEIRAS NO NORDESTE PARAENSERESUMO -O objetivo deste trabalho foi estimar o consumo hídrico em pomar de mangueiras durante as suas fases fenológicas, na região nordeste do Estado do Pará. Para isso, foi instalada e instrumentada uma torre micrometeorológica em um pomar de mangueiras cv. Tommy Atkins de 22 anos de idade, com os dados coletados durante o período reprodutivo das safras de 2010/2011, e de 2011/2012. A evapotranspiração atual de cultura foi estimada pelo balanço de energia através da técnica da razão de Bowen. As safras ocorreram em condições meteorológicas distintas, com menor quantidade de chuva na safra 2, tendo como consequência diferenças significativas na razão de Bowen. A evapotranspiração também sofreu influência das condições meteorológicas ocorridas no período. A evapotranspiração atual da cultura variou entre 402,9 e 420 mm, apresentando um consumo médio diário de 3,8 mm na fase floração, de 4,25 mm na fase de queda, de 3,56 mm na fase formação, de 3,0 mm na fase de maturação e de 3,73 mm para toda a fase reprodutiva.

“…O conhecimento da distribuição estática ou dinâmica do sistema radicular de qualquer cultura constitui-se, também, numa relevante ferramenta para a elaboração de um projeto, bem como num elemento essencial para qualquer plano de manejo da irrigação (Coelho et al, 2001). Choudhury & Soares (1992) estudaram o comportamento do sistema radicular da mangueira, em solo arenoso sob irrigação por aspersão subcopa, cultivar Tommy Atkins, e observaram que, na distribuição horizontal do sistema radicular, 68% das raí-zes de absorção e 86% das raízes de sustentação estão localizadas na faixa de solo compreendida entre 0,9 e 2,6 m em relação ao caule.…”

4RESUMO -Para o manejo adequado de uma cultura, especialmente frutífera perene, torna-se importante o conhecimento de vários fatores agronômicos, entre os quais o desenvolvimento e a distribuição do sistema radicular. Este trabalho objetivou avaliar a distribuição do sistema radicular do porta-enxerto coquinho sob copa da mangueira cultivar Haden. O estudo foi realizado de março/2005 a maio/2007 em solo argiloso, Latossolo Vermelho distrófico, sob vegetação de cerrado, em pomar implantado em 1992, espaçamento de 10 x 10 m, na Fazenda de Ensino, Pesquisa e Extensão da Faculdade de Engenharia/Unesp/Ilha Solteira, localizada no Município de Selvíria-MS. Os tratamentos utilizados foram: plantas testemunhas, sem aplicação de calcário, e plantas que receberam 3,1 t de calcário ha -1 . Avaliou-se o sistema radicular, coletando-se amostras de solo e raízes nas profundidades de 0,0-0,20; 0,20-0,40; 0,40-0,60; 0,60-0,80 e 0,80 a 1,0 m e nas distâncias do tronco de 0,83; 2,49; 4,15 m, classificando as raízes em < 2; 2-5; 5-10 e >10 mm de diâmetro. As raízes de absorção de maior ocorrência foram as de diâmetro menor do que 2 mm nos dois tratamentos. A maior concentração de raízes de absorção ocorreu na faixa compreendida entre 0,0 e 1,66 m do tronco e ao longo do perfil analisado, de 0,0 a 1,0 m de profundidade. A maior concentração de raízes de absorção localizou-se até 0,4 m de profundidade. As plantas que receberam calcário apresentaram aumento de 15,73% de raízes de absorção em relação à testemunha. Termos para indexação: Mangifera indica L., distribuição de raízes, calcário. ROOT SYSTEM DISTRIBUTION OF COQUINHO ROOTSTOCK, ON TOP OF HADEN MANGO CULTIVARABSTRACT -For the adequate management of a crop, especially perennial fruit tree, the knowledge of some agronomic factors becomes important, among them the development and the distribution of the root system. The objective of this work was to evaluate the distribution of the root system of the mango Coquinho rootstock, on top of Haden mango cultivar. The study was conducted between March/05 and May/07, in a clay soil, dystrophic Red Latosol (Haplustox), in an orchard implanted in 1992, spacing of 10 x 10 m, at Experimental Station/Unesp/Ilha Solteira, located in Selvíria-MS State. The treatments were: control plants (no lime added) (T1) and plants that received 3.1 t of lime ha -1 (T2). The root system, was evaluated through samples collected in the depths of 0. 0-0.20; 0.20-0.40; 0.40-0.60; 0.60-0.80 and 0.80 to 1.0 m and from the trunk of 0.83; 2.49; 4.15 m, and the roots were classified into < 2; 2-5; 5-10 e >10 mm. The largest occurrence of absorption roots where those with a diameter smaller than 2 mm in both treatments T1 and T2. The biggest concentration of absorption roots occurred between zero and 1.66 m from the trunk and zero and 1.0 m of depth. The biggest concentration of absorption roots occurred at two first layers of the ground (0.0-0.40 m). Plants that received lime increased 15.73% of absorption roots than plants without lime.
