Abstract |

This study was conducted during 2006/2007and 2007/2008 seasons in the Agricultural experiment station of King Abdulaziz University at Hada AL-sham. Effects of three rates of nitrogen (N) fertilization and eight mixtures of organic materials and their interaction on the straw grain yield of barely, and yield components, as well as the concentration of macro, micro and toxic elements, in barely (grain & straw) and soil, were studied. The main findings were: the highest yield of grain and straw have resulted under the effect of adding mixture of organic materials (sludge + manure + straw) with 100 or 200 kg N/ha, where the highest grain yield was 3975.25 kg grain/ha, under the treatment of the three materials mixture + 200 kg N/ha. The straw yield was 9538.40 kg straw/ha, under the effect of the three materials mixture + 100 kg N/ha. The treatment of the three materials mixture + 100 kg N/ha produced the highest components (the spike length, number of grains/spike and weight of grains/spike) of the barley yield. The highest concentration of nitrogen in the straw and grain resulted under the effect of mixture (sludge + manure) with 200 kg N/ha. The highest concentration of most micro elements resulted under the effect of sludge only + 200 kg of nitrogen, on the other hand the concentration of these elements have dropped by adding other organic materials, like manure or straw, to the sludge, or by reducing the rate of N/ha. Also, the use of (sludge + 200 kg N/ha) resulted in the highest concentration of the toxic elements: nickel, cadmium, chromium and lead, in each of the straw, grain and soil, where the concentration of these elements under the influence of this treatment in barley straw were 3.095, 0.642, 0.40 and 9.28 mg / kg for the four elements respectively. In the grain, the highest concentration of these elements were 0.9006, 0.818, 0.1668,1381 and 0.4 mg / kg, respectively. By the end of the study, the concentration of these elements, under the effect of sludge addition, were 2.60, 0.236, 0.268 and 8.379 mg / kg, respectively. According to the international standards, None of the micro or toxic elements has reached the toxic level, and was within the allowable and non-polluting concentration. |
