Wheat Production under Water-Limited Sandy Soil Conditions Using Bio-Organic Fertilizer Systems

WHEAT crop production and improvement under unfavorable conditions is an important aim for plant breeders, who are looking for genetic diversity in which stress tolerance and high yield can be combined. Sandy soils in dry land areas are marginal for crop production. Two field experiments were conducted during 2003/2004 and 2004/2005 successive winter seasons in a private sandy soil farm at El-Katta Region, Giza Governorate to evaluate three local wheat (Triticuni aestivum L) varieties i.e., Sids 1, Giza 168 and Sakha 69 under some of chemical, organic and bio-fertilizer systems. The agronomic aspccts of adding organic and bio-fertiiizers application to soil on growth and yield parameters are also discussed. The results showed the importance of applying organic manure with bio-fertiiizers compared with chemical fertilizers. Statistical analysis of the data indicated that there were significant differences among the fertilizer treatments for most studied traits. The variation among the three wheat cultivars in its response to fertilizer treatments was found. The Sids 1 cv. gave the highest mean values over the two seasons for all studied traits except protein content in grains. Data evidenced that the second season recorded the highest value for most studied charactcrs among the three used varieties. The correlation coefficient between varieties of wheat yield and its components was highly positive significant under these conditions
