EFFECTS OF DRESSING FERTILIZER AND DIFFERENT NITROGEN DOSES TOGETHER WITH BACTERIA (RHIZOBIUM SPP.) INOCULATION TREATMENTS ON NODULATION AND SOME PARAMETERS OF CHICKPEA (CICER ARIETINUM L.)
Published: 17 Jul 2017
Abstract: The present study was conducted to investigate the effects of dressing fertilizers and different nitrogen doses on nodule and root parameters of chickpea (Cicer arietinum L.) plants. Nitrogen doses were arranged as 0, 30, 60, 90 and 120 kg N ha-1 and dressing fertilizers were applied as 4 kg N da-1. According to the results dressing fertilizer treatments significantly increased average nodule dry weights and root nitrogen concentrations. Number of nodules, nodule weight per plant, nodule nitrogen concentration and root nitrogen concentrations increased with increasing nitrogen doses. Bacteria treatments generally increased nodule weight per plant until a certain nitrogen dose (60 kg N ha-1). Considering all treatments together, it was observed that increasing nitrogen doses together with dressing fertilizer and bacteria treatments yielded remarkable increases especially in average nodule weights and root nitrogen concentrations.
