Background and Objectives: Beans is one of the most important legumes, which has a major contribution to the human diet. It also has a great ability to bio-fix soil nitrogen, and its branches and leaves are also used as animal feed. It has a high protein content and contains essential amino acids, iron, and excellent quality and taste. Iron is one of the essential and micro-elements that plays an important role in soil fertility processes, carbon dioxide stabilization, and increasing product quality, and it is the most important micro-element whose deficiency has a direct impact on the human diet. To solve the problem of iron absorption in calcareous soils, iron complexes using modified EDDHA organic chelators can be used. Therefore, this study was conducted to investigate the role of modified EDDHA iron synthesis complexes in improving the growth and yield of beans (Phaseolus vulgaris L.) in calcareous soils.
Materials & Methods: This experiment was conducted as a factorial based on a randomized complete block design with three replications in the research greenhouse of the Department of Horticultural Science and Engineering, University of Tabriz. Treatments included three levels of calcareous soil (S1, S2, and S3 with 5, 10, and 15% lime, respectively) and five levels of iron (F0, F1, F2, F3, and F4 as a control, EDDHA with acyl chlorides of aliphatic acids; two EDDHA with three amido phenols; EDDHA with aminophenol; and EDDHA with oleic acid epoxide, respectively). Iron complexes with modified EDDHA organic chelating agents were synthesized and used for iron micronutrient feeding to plants.
Results: The highest activity of (Fv/Fo) was observed with the synthesis of modified irons with 10% soil lime, the highest soil EC with 15% soil lime in the EDDHA treatment with acyl chlorides of aliphatic acids 2, and the highest soil pH with 10% lime and no use of modified EDDHA. EDDHA caused a decrease in soil pH at different percentages of lime. EDDHA combined with oleic acid epoxide (F4) produced the highest fresh and dry weight of bean roots. The synthesis of various modified irons in soil with 5% lime increased grain yield.
Conclusion: The study found that a 10% calcareous soil had the highest effectiveness when plants were treated with EDDHA (F4) combined with oleic acid epoxide, which enhanced iron absorption and improved photosynthesis. This modification led to a 10% increase in bean grain yield.
