Abstract

Two-year field experiments were conducted at Shiraz University to evaluate the effects of tillage systems and irrigation methods on water productivity (WP) and yield of three wheat cultivars. Treatments included tillage systems in two levels as conventional tillage and reduced tillage, three irrigation methods as furrow irrigation, solid set sprinkler and wheel move sprinkler and three wheat cultivars. Results showed that interaction of cultivar × tillage system × irrigation methods was significant for plant height, 1000-seeds weight, and number of grains per spike, grain yield, biological yield and WP. Pishtaz cultivar produced more grain yield in conventional tillage system and furrow irrigation. However, this cultivar produced a good amount of yield in reduced tillage and solid set sprinkler irrigation method. Pishtaz cultivar had also the greatest WP in reduced tillage and solid set sprinkler. Reduced tillage also caused an increase in soil organic nitrogen and soil organic carbo

Conclusion

Our results show that Pishtaz cultivar produced more grain yield in conventional tillage system and furrow irrigation. However, this cultivar produced an acceptable amount of yield in reduced tillage and solid set sprinkler irrigation method. Pishtaz cultivar had also the greatest WP in reduced tillage and solid set sprinkler. Therefore, Pishtaz cultivar is good to be recommended to the farmers of the region where water saving is vital over recent water scarcity. Reduced tillage also caused an increase in SON and SOC. Further work should be conducted regarding evaluation of management options to maximize yield and water productivity along with economic evaluation of the different systems.
