Changes in Growth, Pigments and Carbohydrates of Soybean and Rosemary Agroecosystem in Response to Soils Treated with Ceramic Dust in Egypt

The use of pollution as a soil amendment was highly demand for all scientific researchers to face its side effect on the environment. Three replicates of 90 pots culture experiments were conducted at the Faculty of Science, Zagazig University during 2001-2002 to evaluate the impact of ceramic dust as a source of pollution on the growth of soybean (Glycine max L. cv. Crawford) and rosemary (Rosmarinus officinalis L.) grown singly and in combination. We take 1 kg from three different kinds of soils (Delta soil, Desert soil and Sahl El-Tean soil) to be under high control. Ceramic dust was mixed with these soils at five rates varying from 0-g to 200-g dust per kg of soil. The seeds of the two plants were sown on pots containing these soil as follow: One soybean only, one soybean + one rosemary, two soybean + one rosemary, three soybean + one rosemary, one soybean + two rosemary, and one soybean + three rosemary. With Delta soil treatments, ceramic dust at 5% and 10% caused significant increase in plantation success, plant height, yield, pigments and carbohydrates contentsof soybean and rosemary as compared to control. On the other hand, non-significant difference were obtained at 15% and 20% of the dust concentration of applications. The best significant responses showed especially with desert soil. One plant soybean + one plant rosemary are resistant to ceramic dust pollution and we are recommended this kind of cultivation for growing plants in polluted sites.
