Evaluation the growth and yield of some barley genotypes under rainfall conditions at Elfatyh-Derna

Abstract

Field experiment carried out at research station at Elfatyh – Derna – Libya during two growing seasons 2018-2019 and 2019- 2020. Genotypes from national experiments of research center with FAO, genotypes were (Rayhan, Wadi- Fattes , Wadi-Gabiss , Strains10-11 and 15,  Mutation-1, Safeed-1,  Newbola ,  Maimoon ,  Masikloo ,  Ganaaria ,  Glass and Icssad-176)  . the experiment layout in RCBD with 4 replicates. the trails of evaluation were plant height, effective tillers m^-2 , heading and maturity time ,  spire weight , number and weight of spire grains , biological , grain and straw yield,  harvest index and 1000-grain weight . Results showed similar be havior of  genotypes with superior of maimoon in early time of heading and maturity with great grain yield 3.48 and 2.02t/ha comparing to least grain yield 2.41 and 1.33t/ha from Ganaaria and Newbola  genotypes  during  two  seasons respectively. In con closion, genotypes gave a wide chance to selection during time of rain for available time of farming.
