Deficit irrigation effects on sweet corn (Zea mays saccharata Sturt) with drip irrigation system in a semi-arid region

Nitrogen Fertigation to Improve Nitrogen Use Efficiency and Crude Protein on Silage Corn

“…1). Similar findings were put forward by Yazar et al (2002); Oktem et al (2003); Greenwood et al (2008) and Bouazzama et al (2012). As expected, the highest irrigation water (IW) occurred in I4 (125 % Ep) obviously owing to an adequate and/or increased soil water supply during the growing period.…”

“…DM accumulation was, thus, increased by irrigation (Schmaler et al, 2003;Bouazzama et al, 2012). Oktem et al (2003) reported similarly that the fresh ear yield was reduced as the amount of irrigation water decreased and 100% of Ep would be optimal for sweet corn grown in semi-arid regions similar to the area where this work was conducted. They obtained also linear relationships between the amount of water applied and fresh ear yield.…”

Assessment of wheat and maize water productivities and production function for cropping system decisions in arid and semiarid regions

“…Sharma et al, 1990;Zhang et al, 1998;Kang et al, 2000;Yazar et al, 2002;Oktem et al, 2003). With the same database presented in Figures 1 and 2, it could be demonstrated that crop WP can be increased while saving water by reducing the quantity of irrigation water (Figures 3 and 4).…”

Effect of drip irrigation frequency on radish (Raphanus sativus L.) growth and water use

“…Radin et al (1989) indicated that the relationship between water and cotton (Gossypium herbaceum L.) was highly dependent on the frequency of irrigation when the fruit load was heavy, but was generally independent of irrigation frequency before and after the period. Trials conducted by Oktem et al (2003) suggested that among 2-, 4-, 6-and 8-irrigation frequencies, a 2-day irrigation frequency, with 100% ET water application was optimal for sweet corn (Zea mays L.) grown in semi-arid regions. Potato (Solanum tuberosum L.) was subjected to six irrigation frequency treatments (1-, 2-, 3-, 4-, 6-and 8-irrigation frequencies) to evaluate the effects of several irrigation frequencies on potato yield, ET and water use efficiency (WUE) by Kang et al (2004) and the results showed that potato yield, ET and WUE increased as irrigation frequency increased, and the highest yield, ET and WUE values were achieved with an irrigation frequency of once a day.…”
