Farklı Sulama Seviyeleri Altında Yetiştirilen İkinci Ürün Silajlık Mısır ve Sorgum Bitkilerinin Yaprak Su Potansiyellerinin Karşılaştırılması

This study was realized in the research area of the East Mediterranean Transitional Zone Agricultural Research of Instituteduring the 2018 and 2019 generation season.The experiment was carried out to determine the leaf water potential value of silage corn and sorghum plants grown as second crops and compare them with each other.In the experiment, 5 different irrigation tratment (100%, 80%, 60%, 40% and 20%) were applied to the plants. The treatment arranged in a randomized complete block factorial design with three replications.According to the results of the study, the leaf water potential values in both plants increased from 100% irrigation to 20% irrigation.When the values before and after irrigation are evaluated together for two years, the corn plant varied between -13.27 and -21.76 bar in 100% irrigated treatment, -14.07 and -20.15 bar in 80% irrigated treatment, -13.53 and -19.67 bar in 60% irrigated treatment, 12.76 and 21.7 bar in 40% irrigated treatment, -13.30 and -21.14 bar 20% irrigated treatment.Leaf water potential increased negatively with the increase of water deficit.The values after irrigation were lower than the values before irrigation. Lower values were obtained from the silage sorghum plant compared to the corn plant.
