The study was carried out in four different environmental areas of the Central Highlands of Yemen which are (Assam, Bait Alnahmi, Alalip and Telhama), during thesummer season of 2015.

Saqlh barley variety was cultivated in three sites for each area, with an improved technology package ( P2O5 48% with the rate of 80 kg/ha, N 46% with the rate of 100 kg/ha, and seed rate of 160 kg/ha) comparing with farmer practices (120 kg/ha without fertilizing) as a control plant, the experiments were designed according to the Randomized complete Block Design (RCBD).The results showed a highly significant superiority of the improved technology package (p<0.01) for plant height, number of tillers, days to flowering and biological and grain yield, as the percentage of superiority was 88.28, 69.71, 7.6, 63.24, and 60.00%, respectively as compared to the control plant.

The results indicated that there were highly significant differences between locations at (P≤0.01), the sites with application of technology package treatment were superior in the number of tillers per plant and grain yield traits, with a difference superior at (P≤0.05) for the biological yield as compared to the control plant.

The technology package treatment recorded a higher degree by the evaluation in all locations with an increase of 60% over the control plant.

The economic analysis results revealed that the application of the technology package treatment achieved a net return of about 158.152 YR /ha with an increase of 123.274 YR/ha comparing to the control plant (farmer’s method).
