Effects of Deficit Irrigation Treatments on Fatty Acid Contents and Mediterranean Corn Borer Infection Rates of Some Maize (Zea mays indentata Sturt.) Genotypes

This study was conducted over the experimental fields of Siirt University Agricultural Faculty in 2015 and 2016 growing seasons with the first crop 31D24, ADASA16 and P1429 maize genotypes to determine kernel yields and Mediterranean corn borer (Sesamia nonagrioides Lefebvre) infection rates under deficit irrigation treatments (I100, I70, I35). Experiments were conducted in randomized blocks – split plots experimental design with three replications. The Chemical analyses revealed the lowest fatty acid content in full irrigation (I100) and the greatest fatty acid content in deficit irrigation (I35) treatment. As the average of two years, the greatest yield (10400 kg ha-1) was obtained from I100x31D24 interaction and the lowest yield (2853.3 kg ha-1) was obtained from I35xP1429 interaction. The greatest infection rate was observed in full irrigation (I100) (11.87%) and the least infection rate was observed in deficit irrigation treatment (I35) (7.01%). The greatest fatty acid content was observed in deficit irrigation (I35) and the greatest fatty acid content was observed in full irrigation (I100) treatment.
