Barley Productivity and Protein Content as Effected by fertilization Treatments under Calcareous Soil Conditions

Two field experiments were carried- out at Nubaria Agriculture Research Station, North Tahrir, in the two successivegrowing seasons of 2013-2014 and 2014-2015.The experiments were a randomized complete block design (RCBD) withthree replicates. Treatments were: (T1) cerealine bio-Fertilizer, (T2) Mineral nitrogen (45 kg.fad-1), (T3) Organic compost(10m3.fad-1), (T4) 50% mineral nitrogen+ 50% organic compost, (T5) 1/3 organic compost +cerealine bio- Fertilizer+1/3mineral nitrogen, (T6) 50% organic compost + cerealine bio-fertilization and(T7) 50% mineral nitrogen + cerealine bio-Fertilizer. All studied traits (days to heading, days to maturity, filling period, plant height, number of spike.m-2, spikelength, grain yield, biological yield, straw yield, 1000 kernel weight and protein content)were significantly affected byfertilization treatments, except for harvest index and yield efficiency. Also, results showed that T2(mineral nitrogen) andT7(50% mineral nitrogen + cerealine bio-fertilizer) treatments produced the highest values of grain, biological and strawyields, while treatments T4 (50% mineral nitrogen+ 50%organic compost) and T7 (50% mineral nitrogen + cerealine bio.Fertilizer)had the highest values of protein content.
