Water Requirement Estimate for the Reproductive Period of Mango Orchads in the Northeast of the State of Pará, Brazil

Abstract

-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. Termos para indexação: Mangifera indica L, Tommy Atkins, evapotranspiração, razão de Bowen.

Deficit irrigation strategies for subtropical mango farming. A review

“…Therefore, the total average annual water use was 31.63 m 3 tree −1 season −1 . De Souza et al (2016) estimated evapotranspiration rates during the mango reproductive period ranging from 402 to 420 mm, with mean daily water consumption at flowering, fruit fall, fruit formation, fruit maturation, and over the entire period of 3.8, 4.25, 3.56, 3.0, and 3.73 mm, respectively. Da Silva et al (2009) reported the accumulated evapotranspiration during two seasons ranging between 371.4 (70% ET 0 ) and 482.8 mm (100% ET 0 ).…”

Estimation of evapotranspiration and single and dual crop coefficients of acai palm in the Eastern Amazon (Brazil) using the Bowen ratio system

“…Estimation of LE and H, as provided by the Bowen ratio method, must be consistent with the gradient-flow relationship between the components, whose β values close to − 1 may be rejected, according to the accuracy considered for the measurements, which in the present study was 0.2 ℃ for air temperature and 2% for relative air humidity (Souza et al 2016). These values were used to obtain the error-ε (Eq.…”

“…The average ET c results found for the acai palm tree are similar to those found for other palm trees, such as oil palm crops in Mato Grosso, midwestern Brazil, which presented an average ET c of 3.74 mm day −1 (Viana et al 2019) and for coconut palms grown in Sergipe, northeastern Brazil, with an average ET c of 3.90 mm day −1 (Sousa et al 2011). In addition, mango crops grown near the study region, located in the eastern Amazon, presented an average ET c of 3.73 mm day −1 (Souza et al 2016).…”

“…Crop evapotranspiration-ET c is an important variable used for calculating and monitoring water use in different periods. It can be measured by various techniques, such as lysimetry (Peters et al 2017;Xu et al 2018;Silber et al 2019), eddy covariance (Ortega-Farias et al 2010;Prueger et al 2018), soil-water balance (Abdelkhalik et al 2019;Domínguez-Niño et al 2020) and Bowen Ratio-Energy Balance (Souza et al 2016;Chebbi et al 2018).…”

“…BREB has already been used in some studies for perennial crops, for example, in a study conducted by Teixeira and Bastiaanssen (2012) for mango cultivation in Petrolina-PE; by Consoli and Papa (2013) for an orange orchard in Sicily, in Italy; and by Souza et al (2016) for a mango orchard in the northeastern region of Pará, Brazil. The results after application of the method were satisfactory in all those studies.…”
