Cotton yield and water use efficiency at various levels of water and N through drip irrigation under two methods of planting

Soil degradation as a reason for inadequate human nutrition

“…Using microbial processes to increase P uptake (Jackobsen et al 2005), and improve drought tolerance in plants (Marulanda et al 2007) and increase tolerance to salinity (Harmaoui et al 2001) or irrigation with saline water (Sarig et al 1990) and 5. Conserving water in the root zone and enhancing the efficiency of its use through improving soil structure and quality by using organic amendments, NT and CA (Rockström et al 2007), and using drip irrigation and drip sub-irrigation for decreasing losses and increasing plant uptake (Wallace 2000;Aujla et al 2005;Vishwanathan et al 2002).…”

Effects of different water levels on cotton growth and water use through drip irrigation in an arid region with saline ground water of Northwest China

“…Yazar et al (2002) reported that cotton WUE under drip irrigation was 19.5 kg ha −1 mm −1 in Turkey while Aujla et al (2005) determined that the cotton WUE in India ranged from 14.6 kg ha −1 mm −1 to 22.7 kg ha −1 mm −1 . In this study, the WUE values varied from 8.1 kg ha −1 mm −1 to 11.3 kg ha −1 mm −1 .…”

“…Accordingly, this method has been widely applied for cultivation of commercial crops in many countries. In this type of irrigation method, the volume of soil wetted at a particular water application is controlled by the volume of water added, the discharge rate of the dripper and the soil water content (Aujla et al, 2005). Thus the method is best suited to semi-arid and arid areas where water is scarce, and where low water consuming high value crops can be grown.…”

Evapotranspiration and water-use efficiency of irrigated colored cotton cultivar in semiarid regions

“…All of these studies have greatly contributed to an increase in crop productivity by using less water and improving new drought-tolerant cotton varieties. Also, some studies have been conducted for increasing cotton crop yield with less water consumption [11][12][13][14]. By comparing irrigation systems, a single-row cotton crop was more water efficient when irrigated by furrow line while a double-row crop was more water efficient when a dripping irrigation system was used [5].…”
