Abstract

Three grapevine fields with the same varieties were selected on sandy soils in Assiut Governorate. All grapevines were 5 years old. The study started in the growing season 2004 and conducted in the growing seasons 2005 and 2006 to evaluate some soil amendments which are used as a seedbed for grapevines orchards in Assiut desert and their effect on vineyard productivity, quality and the soil water relations.
The selected grapevines fields were in sandy calcareous soils; drip irrigated with underground water but differ in their seedbed amendments. One of the studied sites was amended with clay sediment and the second was amended with farmyard manure. The third site was selected to be without any amendment.
Growth parameters, yield and quality of vine varieties were significantly affected by soil amendments compared to that without it. Ruby seedless has the superiority in yield and quality in the presence of clay sediment followed by FYM as a seedbed amendment. Red Romy variety had the highest acidity value under clay sediment amendment, while Ruby seedless had the highest values of TSS. Some physical and chemical properties of the seedbed samples under study were improved.
Clay sediments were found to be more capable to retain more water compared with FYM seedbed amendment. Soils containing more content of clay seemed to have more salt accumulation compared to the soil containing FYM.
