Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Agriculture - Department of Agronomy Summary: Two field experiments were carried out during 2015/2016 and 2016/2017 winter seasons at Agric. Res. Stat., Fac. Agric., Cairo Univ. Giza, Egypt to study the effect of four NPK fertilizer rates (N₁₅P7.5K₁₂, N₃₀P₁₅K₂₄, N₄₅P₂₂.₅K₃₆ and N₆₀P₃₀K₄₈) and four seeding rates i.e. 100 grains m⁻²(22 kg feddan⁻¹), 150 grains m⁻² (33 kg feddan⁻¹), 200 grains m⁻²(44 kg feddan⁻¹) and 250 grains m-2 (55 kg feddan⁻¹) on barley growth, grain yield, grain quality and nitrogen use efficiency (NUE). For growth and yield attributes, results showed that NPK fertilizers rates had significant effect on growth, yield and its attributes, grain quality traits and NUE parametersو except spike length in both seasons. Also, plant height, weight of grains spike⁻¹ and 1000-grain weight were not significantly affected by NPK fertilizer rates in 2016/2017 season. All the studied traits increased by increasing NPK fertilizer rates during 2015/16 and 2016/17 seasons. The highest (N₆₀P₃₀K₄₈) rate gave the highest values of plant height, No. of shoots and spikes m⁻², and Grains weight spike-1 in both seasons. the greatest No. of shoots and spikes m⁻², Grain weight spike-1and spike length were obtained with the lower seeding rates (100 grains m⁻² : 22 kg feddan⁻¹ or 150 grains m⁻²) in both seasons, however, the tallest plants were observed at higher seeding rate (250 grains ⁻² or 55 kg feddan⁻¹). For biological, grains and straw yields as well as harvest index, application of N₄₅P₂₂.₅K₃₆ fertilizer rate produced the greatest of grain yield feddan⁻¹) and harvest index in both seasons. Straw yield feddan-1increased gradually with increasing NPK rate to N₆₀P₃₀K₄₈.. Biological yield of all fertilizer rate were significantly equal. Biological yield and straw yields significantly increased with increasing seeding rat up to 250 grains ⁻² (55 kg feddan⁻¹) in both seasons. Seeding rate 200 grains ⁻² (44 kg feddan⁻¹) produced the highest grain yield feddan⁻¹ and harvest index in both seasons
