EFFECT OF SOME ORGANIC TREATMENTS ON YIELD AND FRUIT QUALITY OF 'COSTATA' PERSIMMON TREES

Autor: Soaad A. Mohamed, Refat A. Youssef

Publikováno v: Fayoum Journal of Agricultural Research and Development. 29:82-95

The aim of this study is to investigate the effect of foliarapplication of some organic substances (humic acid, fulvic acid and Algaeextract) on vegetative growth, yield and fruit quality of “Costata”persimmon trees grown on clay loamy soil under

Two kinds of sewage sludge composts were applied separately to a crop field consisting of volcanic ash soil (Andosoil) twice a year at 10 t/ha for 12 years since 1978 and the changes in the concentrations of total and soluble Zn and Cu in the sewage

A method of extraction of phytosiderophores from soils was developed. By this method, the contribution of each phytosiderophore to the plant iron status could be determined. It was observed that the ammonium carbonate extraction recovered 76–99% of

Root-induced changes in the rhizosphere of plants. I. pH changes in relation to the bulk soil

Autor: Refat A. Youssef, Mitsuo Chino

Publikováno v: Soil Science and Plant Nutrition. 35:461-468

The rhizobox system offers quantitative information concerning the pH changes and the range of the rhizosphere. Changes in pH values around the roots (barley and soybean) were investigated using a rhizobox. The results indicated that the pH values in

Root-induced changes in the rhizosphere of plants. II. distribution of heavy metals across the rhizosphere in soils

Autor: Refat A. Youssef, Mitsuo Chino

Publikováno v: Soil Science and Plant Nutrition. 35:609-621

Three experiments were carried out using the rhizobox system to determine the distribution of heavy metals (Cu, Zn, Mn, and Fe) across the rhizosphere of barley (Hordeum vulgare L., var. Dorirumugi). The movement of 65Zn, 54Mn, and 59Fe within the rh

Development of a new rhizobox system to study the nutrient status in the rhizosphere

Autor: Refat A. Youssef, Mitsuo Chino

Publikováno v: Soil Science and Plant Nutrition. 34:461-465

The conditions at the soil-root interface are sometimes considerably different from those at a distance from the roots (MARSCHNER 1986), and many researchers have been interested in studying the characteristics of this zone (rhizosphere) in relation
