Two field experiments were conducted in the Nile district (7 km northeast of Babylon province ) during both seasons (2021) and (2022).In order to study the response of two cultivars of broad beans to phosphorous and thiamine broad beans, the split split plots experiment was applied according to the randomized complete block design (R.C.B.D) with three replicates. The main plots included the cultivars (Italian Franchi, Spanish Fito), while the sub- plots included fertilization with phosphorous at four levels (0 kg h¯¹, 80 kg h¯¹, 160 kg h¯¹, 240 kg ha¯ ¹ )While the plots were occupied under secondary spraying with thiamine at a concentration of (0 mg L¯¹, 100 mg L¯¹, 200 mg L¯¹). The results were analyzed statistically using the Genestat program, and the averages were compared on the basis of the least significant difference LSD 0.05, and the results can be summarized as follows: The studied cultivars differed significantly in the vegetative growth, yield and quality indicators for all of both study seasons, as the Franchi cultivar was significantly excelled on the Fito cultivar in the studied traits by registering the highest averages for the studied traits.The percentage of nitrogen was (3.36 and 3.37%), the percentage of phosphorus was (0.29 and 0.32%), the percentage of potassium was (4.87 and 4.52%), the weight of the seeds in the green pod was (16.38 and 17.93) grams, the weight of the seeds after drying was (9.52). and 10.44) g for both seasons, respectively. The treatment of adding phosphorous (240 kg ¯¹) was significantly excelled on the rest of the treatments in terms of vegetative growth, yield, and quality indicators for all of them, and for both seasons.The highest averages were recorded for the studied traits, including the percentage of phosphorus (0.38 and 0.40%), the percentage of potassium (5.45 and 5.37%), the weight of the seeds in the green pod (22.43 and 22.93) g, the weight of the seeds after drying (11.09 and 11.69) g for both seasons. respectively. The addition of thiamine caused a significant increase in all indicators of vegetative growth, yield and quality, especially the concentration (200 mg L¯¹) by recording the highest averages for the studied traits, as the percentage of nitrogen reached (3.36 and 3.35)%,The percentage of phosphorus (0.41 and 0.44%), the percentage of potassium (4.81 and 4.69%), the weight of the seeds in the green pod (17.21 and 17.94) g, the weight of the seeds after drying (9.37 and 10.07) g for both seasons, respectively. The triple interaction treatment (Franchi cultivar, 240 kg h¯¹ and 200 mg l¯¹) was significantly excelled in all indicators of vegetative growth, yield and quality, where the studied traits gave the highest averages for the studied traits. The percentage of nitrogen was (3.57 and 3.62%), the percentage of phosphorus (0.43 and 0.48%), the percentage of potassium (5.25 and 5.98%), the weight of the seeds in the green pod was (27.33 and 28.97) g, the weight of the seeds after drying was (13.60). and 14.00) gm for both seasons, respectively.
