A comparison study on effect of organic and mineral fertilizers on some wheat characteristics grown on the nile alluvial and desert sandy soils [electronic resource].

Includes references.

Two field experiments were conducted during a winter growing season of 2007 on two soil types of newly reclaimed and ancient agricultural areas, however, their soils having different origins and characteristics (i.e., desert sandy soil calcareous in nature at Noubaria area and the Nile alluvial clayey one at Gemaiza Agric. Exp. Station) to evaluate the effect of organic compost (as a source of N-organic) on availability and uptake of essential nutrients and their positively effects on plant growth and nutritional status at different physiological stages of wheat (Triticum aestivum, Sakha 69 c.v.) as well as yield and its components. However, a partial 20% of N-mineral was substituted by N-organic manure derived from composted com stalks and broad bean straw as compared to applying 100 % N-mineral fertilizer in form of ammonium sulphate (20.6 % N). The obtained data show that the applied composted plant residues increased dry matter yield of wheat plants at all physiological stages under study in both the studied soil types. Also, the application of com posted plant materials was achieved as a superiority effect on nitrogen, phosphorus and potassium uptake by wheat plants. Key words: Composted plant residues, nutritional status of wheat, available NPK in soil, Nile alluvial and sandy soils.
