Abstract
Two field experiments were carried out at Sakha Agricultural Research Station, during 2001/2002 and 200212003 seasons to study the response of two barley
cultivars (Giza 123 and Giza 2000) to nitrogen levels (0, 30 and 45 kg N/fad.) and biofertilizer sources (noninoculated, microbin, nitrobin, ceriatin and rizobactreren). A split-split plot design with four replications was used in this study. The studied trait were; days to heading, days to maturity, plant height, number of spikes/m2, spike length, number of grains/spike, 1000-grain weight, biological, grain and straw yields/fad., harvest index, crude protein %,and protein yield /fad.
The results indicated that Giza 123 cultivar gave the highest values of plant height, number of splkes/m", spike length, 1000-grain weight, and biological, grain, straw and protein yields/fad. On the other hand the lowest values were obtained using Giza 2000 cultivar ..
With respect to nitrogen, increasing it's level from 0 to 45 kg N/fad. Led to significant increases in all studied traits except in case of 1000 grain weight.
The results also showed that all biofertilizer treatments significantly increased grain yield, yield components and its quality traits. Meanwhile, the highest values were recorded when seed was inoculated with Nitrobin.
It could be concluded that cultivation of Giza 123 under 45 kgN/fad. combined with any of the studied biofertilizer sources give the best agronomic and quality traits.
