“…Maximum hourly sap flow under well watered conditions was 32.5 and 33.9 g stalk −1 h −1 for N19 and G73, respectively, which was comparable with maximum daily sap flow rates of 30-55 g stalk −1 h −1 for sugarcane cultivar CP 66-345 grown in Morocco under irrigated conditions (Chabot et al, 2005). Nassif and Marin (2013) reported hourly sap flow rates of 80-320 g stalk −1 h −1 over a five day measurement period but this study did not report any data rejection criteria or sap flow equipment accuracy. Sap flow decreased by approximately 50% at midday in G73 stressed treatments, and decreased by 90% at midday in the N19 stressed treatment in response to water stress (Fig.…”

“…The CP and SP areas had mean transpiration rates of 1.32 and 0.99 L m -2 of green leaf d -1 , respectively. Nassif et al (2014), worked with the same sugarcane cultivar with stalks bearing approximately 0.34 m 2 of leaf, and cultivated without soil cover from May 14 th to 30 th and from June 16 th to July 4 th . They recorded an average transpiration rate of 1,52 L m -2 of d -1 green leaf.…”

“…In the present study, the values converted to average transpiration blades were 3.45 and 2.39 mm d -1 for the CP and SP areas, respectively. In comparison, Nassif et al (2014), used sap flow sensors and recorded transpiration rates varying between 3.4 and 4.2 mm d -1 for sugarcane grown in the municipality of Piracicaba.…”

Residual straw affects the physical, chemical, and biological attributes of soil and can influence plant transpiration and the evaporation of water from the soil. Therefore, in this study, we evaluated the effect of straw on evaporation and transpiration of sugarcane. The experiment was conducted in a 2.5 ha area irrigated via a central pivot. The experiment consisted of two treatments, namely, with and without straw removal of soil. Evaporation was determined by means of equations and transpiration with sap flow sensors using the heat balance method. Evapotranspiration of the crop was measured using the Bowen ratio method and compared with the sum of the collected soil evaporation and transpiration data. On the basis of relationship analysis between the evapotranspiration of the crop measured using the Bowen ratio method and the sum of the sap flow combined with estimates of the evaporation of soil water, we obtained coefficient of determination values of 0.65 and 0.69, and angular coefficients of 1.01 and 0.96 for treatments with and without straw, respectively. We accordingly found that the use of straw on the soil reduces the evaporation of soil water and increases the transpiration and evapotranspiration of the crop.

“…Since the energy crisis caused by the oil price rises, there has been a worldwide increase in the search for alternative fossil fuels, boosting the demand for sugar and ethanol from sugarcane crops (Nassif et al, 2014). In order to meet this demand, sugarcane cultivation, which had been previously concentrated in areas with high water availability, expanded to areas with limited conditions, especially to the states of Goiás and Mato Grosso do Sul (Brazil).…”

A B S T R A C TThe aim of this study was to evaluate the water productivity into biomass and into sugar for 23 sugarcane varieties (second ratoon crop) under two levels of drip irrigation. Two experiments were conducted in a greenhouse. Experiment 1 comprised nine sugarcane varieties grown in a clay soil and Experiment 2 was composed of 14 varieties in a sandyloam soil. Moreover, two irrigation treatments were adopted: T100 -full irrigation with 100% crop evapotranspiration replacement, maintaining soil moisture near field capacity for each variety; and T70 -irrigation with 70% T100 water depth. Water productivity was evaluated in terms of stem fresh biomass (WP FB ) and sugar (WP GSY ). The results showed that WP FB ranged from 11.45 to 18.45 kg m -3 . The highest values were observed for varieties CTC14, CTC6, RB867515, and SP81-3250 (in T100) and for the varieties CTC6 and CTC14 (in T70). The WP GSY values ranged from 1.68 to 2.22 kg m -3 , with emphasis placed on CTC6, RB9675-15, SP81-3250, and RB925211 (in T100) and on CTC6, CTC14, and SP81-3250 (in T70).Produtividade da água em açúcar e biomassa de variedades de cana-de-açúcar R E S U M O Objetivou-se, neste estudo, avaliar a produtividade da água em biomassa e açúcar de 23 variedades de cana-de-açúcar (segunda soqueira) irrigada por gotejamento sob dois níveis de irrigação. Dois experimentos foram instalados e conduzidos em casa de vegetação. Experimento 1: nove variedades em um solo argiloso e Experimento 2: 14 variedades em um solo franco-arenoso. Dois tratamentos de irrigação foram adotados: T100 -plenamente irrigado com reposição de 100% da evapotranspiração de cada variedade, mantendo a umidade do solo próximo à capacidade de campo; e T70 -irrigação com 70% da lâmina aplicada no tratamento T100. Avaliaram-se a produtividade da água em biomassa fresca de colmo (PA BFC ) e a produtividade da água em açúcar (PA RBA ). Houve variação na PA BFC de 11,45 a 18,45 kg m -3 . Observaram-se os maiores valores nas variedades CTC14, CTC6, RB867515 e SP81-3250 (T100) e nas variedades CTC6 e CTC14 (T70). A PA RBA variou de 1,68 a 2,22 kg m -3 , destaque para as variedades CTC6, RB967515, SP81-3250 e RB925211 em T100 e CTC6, CTC14 e SP81-3250 em T70.
