| Popis: | Besides irrigation water (IW) quantity and quality, there is a decrease also in soil quality and fertility. Agricultural production lands are decreasing both in quantity and quality. There is a search for different operational alternatives in sandy soils with low production potentials. Drip irrigation is primarily practiced attain get greater yields per unit area. This study was conducted under sand soil conditions, commonly preferred for peanut farming, in the 2017-2018 growing seasons. A drip irrigation system was used in production. Halisbey, NC-7, and Sultan cultivars were used as plant materials. Two different irrigation intervals (2 and 4 days) and four different irrigation levels (I50, I75, I100 and I125, calculated based on cumulative evaporation from the class-A pan) were applied. The data of five vegetative traits, including grain yield, were evaluated by regression and GGE biplot analysis. In addition, applied IW quantity, evapotranspiration and water use efficiency (WUE) were assessed by econometric analysis. Evapotranspiration values varied between 402-832 mm, applied IW quantities between 313-783 mm, yields between 5,269-8,269 kg ha-1, WUE values between 0.63-1.55 kg ha-1 m-3, economic water productivity over gross revenues between 1.29-3.81 $ m-3 and benefit and cost ratios varied between 4.73-10.95. The GGE biplot statistical method is a useful tool in the evaluation of irrigation research where the number of applications and materials is high. As a results of the study, a 2-day irrigation interval and 75% of pan evaporation could be used in the irrigation of peanut plants grown under sandy soil conditions. |
