Abstract

This study investigates the effects of increasing doses of sewage sludge with Rhizobium inoculation on lentil (Lens culinaris Medic.) straw and grain macro, micro and heavy metal contents in 2003-2004 and 2004-2005 growing seasons. Experiment was conducted as a randomized complete block design with 3 replications. At the end of the study, it was seen that Rhizobium inoculation affects the N, Mg, and Pb contents of the lentil straw on by P<0.05, P and Ca contents by P<0.01 in the first year; the N, Fe, and Zn contents on P<0.05 level, on the Pb content P<0.01 level in the second year. Lentil grains were affected only on the K, Fe, Pb, and Cd contents by P<0.05. Sewage sludge applications were used to detect the effects on the N, Mg, Fe, Mn and Cu contents of the lentil straw by P<0.01, Co content by P<0.05, and Pb content by P<0.01 in first year; on the N, K, Zn and Pb contents by P<0.01, P and Mn contents by P<0.01, on the Mg, Fe, Cu, and Co contents by P<0.05 in the second year. Effects received by the lentil grains are as follows: The N, K, and Cu contents by P<0.01, on the Pb, Fe, P, and Mg contents by P<0.01, on the Ca and Zn contents by P<0.05 in the first year; on the P, K, Ca, Mg, Fe, Mn, Zn, Cu and Co contents by P<0.01, on the Pb content by P<0.05 in the second year. The effects of inoculation on the lentil straw and grain, regarding the nutrient and heavy metal contents were determined to be insignificant. This result may be a result of weak inoculation application and the heavy metal content of the sewage sludge, as well as the negative effects of Rhizobium inoculation.
