Effect of foliar application of phosphorus on growth and development of Vicia faba L. under magnesium levels

الملخص EN

The present experiment was done to study the interaction of foliar application effect of phosphorus and magnesium on faba bean plants.

This study conducted in Biology Department in the College of Science- University of Salahaddin- Erbil during November 2, 2017 to February 20, 2018 in the greenhouse as pot experiment.

The experiment consisted of combination treatments of foliar spray with different phosphorus (P) concentrations at doses (0, 100, 200, 300, 400, 500 ppm) and soil irrigation by two magnesium (Mg) concentrations (0, 200 ppm).

This study consists of 12 treatments with three replications.

The following parameters has been observed: plant height, leaf and branch numbers, water content and dry weight of shoot system, leaf area, stem diameter, yield components including pod and seed numbers, dry weight of 100 seeds and photosynthetic pigments.

The results indicate that phosphorus and magnesium interactions significantly increase plant height, number of branches, water content, leaf area, number of pods per plant, carotenoid contents
