Effects of alternate partial root-zone irrigation on yield and water use of sticky maize with fertigation

Regulated deficit irrigation for crop production under drought stress. A review

“…6 Agronomic practices for improving crop productivity under regulated deficit irrigation RDI has been used for many field crops such as wheat (Hongbo et al 2005), maize (Liang et al 2013;Wang et al 2012b), cotton (Du et al 2008b;Li and Lascano 2011;Ünlü et al 2011), rapeseed (Brassica napus) (Hamzei and Soltani 2012), soybean (Mishra et al 2013), common bean (Simsek et al 2011), mung bean (Bourgault et al 2010), sunflower (Garofalo and Rinaldi 2015), potato (Ahmadi et al 2014), and tomato ). And, this technology has been used in some woody plant species, such as grapevine , apple (Yang et al 2012b), olive trees (Ghrab et al 2013), nectarine (Prunus persica L.) (De la Rosa et al 2015), and wine grape (Vitis vinifera L.) (De la Hera et al 2007).…”

Effects of alternate furrow irrigation on the biomass and quality of alfalfa (Medicago sativa)

“…This does not agree with the results for tomato, potato, pepper, soybean, grapevines, pear, peach, maize, cotton and wheat (Kirda et al, 2004;Erdem et al, 2006;Foday et al, 2012;Graterol et al, 1993;Dos Santos et al, 2003;Kang et al, 2002;Gong et al, 2004;Liang et al, 2013;Tang et al, 2005;Yang et al, 2010). This type of difference derives from the harvest times and harvest targets of different plants.…”

“…Irrigation mode is considered an important way to increase the WUE of alfalfa, especially in drought situations (Montazar and Sadeghi, 2008;Alam et al, 2002;Hanson et al, 2007). Alternate furrow irrigation has proved to be an effective water-saving irrigation mode (Kang and Zhang, 2004), which increases the WUE of tomato, potato, pepper, soybean, grapevines, pear, peach, maize, cotton and wheat without much reduction in yield (Kirda et al, 2004;Liu et al, 2006;Foday et al, 2012;Graterol et al, 1993;Dos Santos et al, 2003;Kang et al, 2002;Gong et al, 2004;Liang et al, 2013;Tang et al, 2005;Yang et al, 2010). This study shows that alternate furrow irrigation increases the IWUE t and IWUE ht by 40-46% and 36-42%, respectively, compared to conventional irrigation.…”

“…Alfalfa is often harvested more than two times, but field crops and horticultural crops are only harvested once because the harvest target is vegetative mass for alfalfa and seeds, fruits and tubers for annual and horticultural crops. As far as the first and the second harvest times for alfalfa are concerned, alternate furrow irrigation maintains a reasonable biomass because it keeps approximately 50% of the root system in a relative dry condition, which provides regular dry signals for stomatal inhibition and sharply reduces invalid transpiration, but exerts less influence on alfalfa photosynthesis (Davies and Zhang, 1991;Kang et al, 1998), and this physiological process is similar to that of annual and horticultural crops (Kirda et al, 2004;Liu et al, 2006;Foday et al, 2012;Graterol et al, 1993;Dos Santos et al, 2003;Kang et al, 2002;Gong et al, 2004;Liang et al, 2013;Tang et al, 2005;Yang et al, 2010). Meanwhile, 50% of root systems in the wet conditions keep their natural function to absorb more water and nutrition at 20-40 cm soil layer because alternate furrow irrigation significantly increases soil water moisture at 20-40 cm layer at the first and second harvest times.…”

“…It also ameliorates soil texture and accelerates the decomposition of soil organic carbon (Avice et al, 2003;Erice et al, 2007). Many previous studies have shown that alternate furrow irrigation is a potent tool for irrigating many horticultural crops (tomato, potato, pepper, soybean, grapevines, pear, peach) (Kirda et al, 2004;Liu et al, 2006;Foday et al, 2012;Graterol et al, 1993;Dos Santos et al, 2003;Kang et al, 2002;Gong et al, 2004) and field crops (maize, cotton and wheat) (Liang et al, 2013;Tang et al, 2005, Yang et al, 2010 due to its low cost and easy implementation (Kang and Zhang, 2004). Most of these studies focus on harvesting the seed, fruits and tubers, while neglecting the vegetative mass.…”
