Abstract
To study the Impact of 2020 Dragon Storm on chocolate spot disease, growth, and yield of faba bean in Egypt, field experiment using faba bean cultivars namely Giza 843, Sakha 1 and Giza 40 was carried out during seasons 2019/2020 and 2020/2021 at Etay El-Baroud Agricultural Research Station Farm, El-Beheira Governorate. In the first season, the rain ranged between 1/3/2020 - 11/3/2020 from 0.00 to 0.38 mm day-1 but on 12/3/2020 heavy rain (26.3 mm day-1) and thunderstorms were happened. The relative humidity recorded 82.08, 79.43 and 69.10% on 12/3, 13/3 and 14/3/2020. The maximum temperature decreased on 12/3 and 13/3/2020 to 20.16 and 21.80°C, respectively. After 5 days from the beginning the storm, the disease severity increased sharply but Giza 843 had the least value followed by Sakha 1 and Giza 40 with averages of 23.70, 28.89 and 43.70%, respectively . In contrast in the second season, the disease severity showed normal averages . In the first season, there was a positive strong correlation between disease severity and rain and the relative humidity. Giza 40 was the earliest in the flowering and maturing dates significantly followed by another two cultivars (Sakha 1 and Giza 40). Giza 843 cv. had the best value of plant height with an average of 94.33 cm and exceeded Sakha 1 and Giza 40 significantly in the number of branches/plant, number of pods/plant, seed yield/plant (g), seed yield/plot (Kg) and seed yield/feddan (ardab) with averages of 3.68, 17.97, 32.11, 4.26 and 16.55, respectively.
