Abstract

The experiment was conducted during the 2018 season at the research station of the College of Agriculture and Forestry (University of Mosul, Iraq) to investigate the effect of volcanic rock dust (VRD) (0, 125, 250 g m-2) and the fertilizer chelated Iron Fe-EDTA (0, 100, 200 mg L-1) on the bacteria Rhizobium fabae, and the growth and yield of two broad bean (Vicia faba L.) varieties, Histal and Aquadulce. A randomized complete block design was used with three replicates and least significant difference (LSD) to compare means at a significance level of 0.05. Results showed that VRD 250 g m-2 obtained the highest significant mean for the following traits: leaf area index (LAI), number of branches per plant, leaf contents of chlorophyll and total iron, number of effective bacteria nodules per plant, 100-seed weight, plant yield, and percentage of protein in the seeds. On the other hand, 200 mg L-1 Fe-EDTA obtained the highest significant mean of all the traits for both varieties, except for LAI and number of branches per plant. The application of Fe-EDTA per plant had no significant effect on the leaf content of chlorophyll for both varieties and the percentage of protein in the seeds for variety Aquadulce. The interaction of VRD 250 g m-2 with 200 mg L-1 Fe-EDTA achieved the highest significant average for all the traits, except for plant height.

火山岩粉尘和Fe-EDTA对蚕豆根瘤细菌及生长和产量的影响

本试验于2018年季节在伊拉克摩苏尔大学农林学院研究站进行，研究了火山岩尘(VRD)(0、125、250 g m-2)和肥料螯合铁Fe-EDTA(0、100、200 mg L-1)对蚕豆根瘤菌(Rhizobium fabae)以及历史和水培两种蚕豆(Vicia faba L.)生长和产量的影响。采用随机完全区组设计，3个重复，最小显著差异(LSD)比较均数，显著性水平为0.05。结果表明，VRD 250 g m-2处理在叶面积指数(LAI)、单株分枝数、叶片叶绿素和总铁含量、单株有效菌结数、百粒重、单株产量和籽粒蛋白质含量方面均达到最高显著平均值。而200 mg L-1 Fe-EDTA处理除叶面积指数(LAI)和单株分枝数外，其余各性状的显著平均值均最高。单株施用Fe-EDTA对水浒品种叶片叶绿素含量和种子蛋白质含量均无显著影响。VRD 250 g m-2与200 mg L-1 Fe-EDTA互作除株高外，其余性状的平均显著性最高。
