| Abstract | ||||
| Field experiments were conducted to evaluate the effect of using sewage sludge as organic fertilizer on different yield parameters of Vicia faba. Sewage sludge treatments rate were 0, 10, 20, 30, and 40 ton/Fed were applied to the soil in three successive additions during 1999-2001. Different rates of residual and repeated application of sewage sludge increased heavy metals concentrations in the soil before sowing and after harvesting of Vicia faba. Sludge treatments did not affect some yield parameters of Vicia faba (Giza461), but, affected mature plant height and number of tillers/plant which increased or decreased at different treatments of sludge. The seed index and fresh and dry weights of shoots and roots were increased. The number of seeds/pot recorded the highest value by 10 ton/Fed of the residual one addition. The lowest value was obtained at 20 ton/Fed two additions. Also, sludge treatments increased mature plant height, seed index, seed density, the number of nodules/plant and fresh and dry weights of nodules of Vicia faba (Giza 461 and 77) except at the highest treatment of two addition and three additions. Generally, it decreased nodules efficiency percentage. In the same time, the percentage of ineffective nodules was increased in case of Vicia faba (Giza 461). However, in case of Vicia faba (Giza 77) in the percentage of effective nodules after 30, 45, and 75 days from sowing was increased except at the high sludge rates of cumulative three additions after 30 and 45 days. In the same time, the percentage ineffective nodules were increased after 30 and 40 days at the highest sludge rates. In addition the percent of nodules which have low efficiency was higher than the percent of high ineffective. The rate of root growth of Vicia faba (Giza 77), after all sludge treatments, recorded lower values than the control except those of 10 and 30 ton/Fed residual one addition. The root tolerance index increased by sludge treatments. The sludge treatments increased the mean mitotic index and those of cumulative three additions treatments were higher than that of residual one addition treatment. Sludge treatments included a number of abnormalities in all mitotic phases and non dividing cells of Vicia faba (Giza 77). The percentage of abnormal cells increased by cumulative three additions treatments than the residual one addition treatment. | ||||
