Response of Growth and Yield of two Broad Bean (Vicia faba L) varieties for antioxidants and diammonium phosphate DAP fertilizer.

In the fall agricultural season of 2021-2022, an experiment was conducted in two areas of Nineveh Governorate, the first experiment in Yarmgah and the second one in Badush, each experiment included two types of board bean Vicia faba L to study their response to antioxidants and ammonium phosphate diphosphate fertilizer. The experiment included two factors, the first factor varieties (Aquadlge and Luz de otono)                                                                                                                                                                        with antioxidants with seven levels.  without the addition of catechins and DAP fertilizer, spray and soak at a concentration of 250 mg. L-1 for each of AsA, B1, B6 with the addition of 20 kg DAP. Spray and soak at a concentration of 500 mg.L-1 for each of AsA, B1, B6 with the addition of 20 kg DAP.H -1.spray and soak at a concentration of 250 mg.L-1 for each of AsA, B1, B6 with the addition of 40 kg DAP.H-1, spray and soak at a concentration of 500 mg.L-1 for each of AsA, B1, B6 with the addition of 40 kg DAP.H-1, spray and soak at a concentration of 250 mg.L-1 for each of AsA, B1, B6 with the addition of 60 kg DAP.H-1, and Spray and soak at a concentration of 500 mg.L-1 for each of AsA, B1, B6 with the addition of 60 kg DAP.H-1).  The seeds were soaked in water with antioxidants for 6 hours before planting and sprayed with antioxidant until complete wetness took place 30 and 45 days of planting, and the results showed the superiority of the Aquadlge Variety over the Luz de otono variety morally at the Yarmgah and Badush experiment sites for all the studied qualities: the chlorophyll content, the number of pods in the plant, the number of seeds per pod, the number of seeds per plant, the weight of 100 seeds and the protein percentage. The seventh level of the fertilizer combination with antioxidants gave the highest value of all the studied qualities: the chlorophyll content, the number of pods in the plant, the number of seeds in the pod, the number of seeds in the plant, the weight of 100 seeds and the percentage of protein.
