| 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. | ||
