| ABSTRACT Two faba bean varieties i. e., Nubaria-1, and Spanish were sown in different cultivated dates 15th of October, November, and December during winter seasons of 2020/2021 and 2021/2022 at different planting distances (30, 25, and 15cm) in sandy loam soil at the experimental farm of El-kassasein Station, Ismailia governorate, Horticulture Research Institute, Agriculture, Research Center, Egypt .The effects of previous factors on the vegetative growth, yield components and green seeds contents of protein, carbohydrates and amino acid (Tyrosine) which is the generator of constructor L-DOPA compound that treated of Parkinsons disease (PD). The results showed that Nubaria-1 obtained augment vegetative growth (plant length, plant fresh and dry weight), yield attributes (number of pods/plant and seeds dry weight percentage), and seeds chemical components percentage (protein, and tyrosine). Meanwhile, Spanish variety was surpassing in number of branches/plant, 100-seed weight, number of seeds/pod, and seeds contents of carbohydrates. Sowing faba bean in 15th November was the optimum date to produce greatest plant growth, green pods, green seeds yield/fed., and pods characteristic as well as seeds chemical contents of carbohydrates, protein, and amino acid (Tyrosine). Planting distances at of 25cm resulted in vigor plant growth then in second order the distance at 30 cm between hills. While, the superiority values of number of pods/plant, 100-seed weight and dry seed weight percentage as well as green seeds chemical contents were established according to space 30cm apart between plants. Conclusively, the interaction between variety Nubaria-1, sowing in 15th November, and planting distance at 30cm increased the chemical components percentage of tyrosine and protein. | ||||
