Two field experiments were conducted at a private farm at El-Salhia region, Sharkia Governorate, Egypt during 2004/2005 and 2005/2006 seasons to study the response of three barley cultivars viz. Giza 123, Giza 124 and Giza 125 to fertilization with three levels from farmyard manure (30, 35 and 40 m3/fad.) and foliar spray with Fertilan 10 (containing micronutrients mixture) under sandy soil conditions. A split-split plot design with three replicates was used in both seasons.
The results revealed that, barley cultivars differed significantly where Giza 124 produced the highest grain and straw yields/fad. and the lowest grain protein content. However, Giza 125 recorded the highest grain protein content and the highest harvest index.
Foliar spray with Fertilan 10 had favourable significant effect on most studied traits. Grain yield/fad. was increased significantly by 14.54% over the two seasons due to this treatment.
The increase of farmyard manure rate up to 40m3/fad. produced significant increases in grain and straw yields/fad. and most of their attributes. These increases were at for with those produced by the addition of 35 m3/fad.
No significant interaction effect could be detected between each two of the factors under study on grain yield/fad. or any of its attributes.
The results indicated that grain yield/fad. was positively and highly significantly correlated with all studied traits including number of spikes/m2, number of grains/spike, weight of grains/spike and 1000-grain weight.
Results cleared that the highest yield could be obtained from sowing Giza 124 barely cv. and addition of 35 m3 FYM with the foliar application of Firtlan 10 , under sandy soil conditions of El- Salhia region , Sharkia Govern orate.
