Abstract
Background: Barley (Hordeum vulgare L.) is known to be one of the most salt-tolerant crops. Barley is used as feed and human food, because of its ability to grow and produce in drought and salinity conditions.
Aims: This research aimed to test the seed germination and the behavior of barley landraces at various salt levels.
Materials and methods: The experiments were conducted at both lab and experimental farm of the Faculty of Agriculture, An-Najah National University, Tulkarm/ Palestine. For the germination experiment, seeds of 20 barley landraces collected from farmers in different regions in the West Bank-Palestine were used, the seeds were planted under four concentrations of salinity (control,100, 200, and 300 mM), in this study. Based on the results of the germination experiment, 4 landraces that exhibited the higher germination rate under salt treatments were selected for the field experiment (HV17, HV18, HV19 and HV20). The four landraces were planted on 2018/2019 growing season in a sand clay soil. The landraces were irrigated with different levels of NaCl (Control 100, 200 & 300 mM).
Results: The field experiment showed that chlorophyll content, length and tiller number were reduced with increasing salinity levels. The seeds and straw yield were also reduced with higher salt level, straw yield at (Control, 100, 200 and 300 mM) were (478, 305, 283 and 250 Kg/du) respectively, however, grain yield at control (338 kg/du), 100mM (238 kg/du) was significantly higher than both at 200mM and 300mM (180 and 133 kg/du) respectively, no significant difference among the landraces was observed however, grain yield for HV-19 and HV-17 was the best (247 and 237 kg/du) respectively, as well as with straw yield (375 and 358 kg/du) respectively. Electrical conductivity (EC), Sodium and Chloride concentration were increased with increasing salinity levels.
Conclusion: the current study demonstrated the ability of barley landraces to grow under saline water. Landraces HV-8, HV-16, HV-17, HV-18, HV-19 and HV-20 are they highest germination percentage. The HV-19 and HV-17 landraces are the best result in grain and straw yield.
