Water relations in sugarcane and response to water deficits

Development, yield and quality attributes of sugarcane cultivars fertigated by subsurface drip irrigation

“…POL cane values in the 2 nd ratoon were higher compared with the 1 st ratoon, which is possibly associated with the shorter duration of the 1 st ratoon, as well as with the fact that irrigations had not been suspended yet. This criterion of suspension of irrigations before harvest has been adopted by many authors in order to favor maturation (Pires et al, 2008;Inman-Bamber & Smith, 2005). Gava et al (2011) and Silva et al (2014) obtained mean values of POL cane similar to those found in the present study ( Table 7).…”

“…However, different responses of the cultivars to water availability should be taken into account (Ribeiro et al, 2013), with consequent effect on water use efficiency. The knowledge on the response of different genotypes in relation to water deficiency or to the responsiveness to water helps genetic improvement programs (Inman-Bamber & Smith, 2005) and variety management in different cultivation environments.…”

Water Use Efficiency of the First Ratoon Cane by Eddy Covariance Technique

“…Total planting area of sugarcane in Thailand is 1.42 million ha rely on irrigation to a small extent (20%) to produce a viable crop [2]. Seasonal water requirements for sugarcane have been derived mostly from a relationship between cane yield and water used through transpiration and soil evaporation [3]. Water flux and water use can be measured using many methods and Eddy Covariance technique (EC) is the new method which do not interfere with process of gas exchange between the surface source and the atmosphere [4].…”

Stalk yield of sugarcane cultivars under different water regimes by subsurface drip irrigation

“…Under this condition, there is an increase in tillering and elongation of the stalks due to the large transport of carbohydrates from the roots to the shoots (Inman-Bamber & Smith, 2005;Singh et al, 2007).…”
