Abstract

The experiment was conducted in a private research farm in the open field under Bani Mazar city, Minia Governorate conditions. during two successive seasons, 2020 and 2021 to study the effect of three planting dates, 5th, 15th and 25th August, and six hybrids of cucumber (Bahi, Mayadine, Hayel, El-Joker, Madin, and Raider) and their interaction on vegetative growth, flowering, and yield components. The results indicated that the main stem length significantly increased in Hybrid Madin when planted on August, 25. Mayadine hybrid was the earliest in flowering and harvesting compared to the other hybrid in the first planting date (August, 5). El-Joker Hybrid recorded the highest sex ratio when grown on August, 25. Fruit yield per plant (kg) and the No. of fruits per plant were associated with the hybrids of Mayadine, Hayel and El-Joker when grown on August 25. Moreover, the high content of phosphorous, potassium and dry matter was in the Hayel cucumber hybrid when it was planted in the third sowing date (August 25). In general, the results recommended that the Hayel hybrid was most suitable for cultivation in the open field on August 25, as it was superior in yield and nutritional values of fruits under the conditions of Minia Governorate.
