The Effect of Using Different Concentrations of Nitric Acid and Potassium Nitrate on Stimulating Germination of Two Barley Cultivars

Abstract

The results showed that there were significant differences between the two cultivars in some studied traits.  Alriyhan cultivar gave the highest values ​​for germination speed, germination ratio, germination strength for the first tool (germination speed), and germination strength for the second tool (germination ratio). While there were no significant differences in root length, wet weight between the two cultivars. The T10 and T6 treatment gave the highest values in germination speed, germination ratio, feather length, dry weight, germination strength of the first tool (germination speed), germination strength of the second tool (germination ratio) when were compared to the rest of the treatments. While there were no significant differences between treatments in root length, feather length, wet weight and dry weight. A laboratory experiment was conducted at the Soil and Fertilization Laboratory of the Soil and Water Department - Faculty of Agriculture - Sebha University. During the winter season 2019/2020, by using a complete random design (CRD) with three replicates to the applied two barley cultivars (Napola, Alriyhan) to the effect of soaking in eleven treatments (T1 without soaking, T2 distilled water soaking 3 hours, T3 distilled water soaking 6 hours, KNO₃ T4 5% soak 3 hours, KNO₃ T5 10% soak 3 hours, KNO3 T6 5% soak 6 hours, KNO₃ T7 10% soak 6 hours, HNO₃ T8 0.05 standard soak 3 hours, HNO₃ T9 0.1 standard soak 3 hours, HNO₃ T10 0.05 standard soaking 6 hours, HNO₃ T11 0.1 standard soaking 6 hours).
