The effect of 2.4-Dichlorophenoxy Butyric acid in low concentrations on the yield and nitrogen content of broad beans ( Vicia faba L.)

Abstract: The effect of the foliar application of three concentrations of 2.4-DB and metal ions on broad beans was studied. 15 ppm 2.4-DB followed by 1500 ppm Fe2 + or 1500 ppm Mn2 + caused a significant decrease in the mean number of pods, dry matter and nitrogen content of the plants. The same concentration followed by spraying with 1500 ppm Fe2 + and 1500 ppm Mn2 + increased the dry weight of pods and whole plants by over 35% and the nitrogen contents by over 25%. The use of 30 ppm 2,4-DB proceeded by 3000 ppm Fe2+ or 3000 ppm Mn2+ caused even more reduction in the dry weight and total nitrogen contents, but using the same concentration of 2.4-DB with the two metal ions in combination, resulted in a great increase in yield, dry matter and nitrogen contents, which exceeded 50% of the control treatment. A concentration of 60 ppm 2.4-DB followed by 6000 ppm Fe2 + and/or 6000 ppm Mn2+ caused a drastic reduction in mean number of pods, dry matter and total nitrogen contents, especially when both Fe2+ and Mn2+ were used together.
