| Abstract | ||||
| The paper presents the role of Casuarina and Jojoba windbreaks on microclimate, growth and productivity of quinoa (Chenopodium quinoa Willd.) planted in affected areas by aeolian deposits at (Cairo Ismailia Desert Road) Ismailia Governorate, Egypt during two successive growing seasons 2020/2021and 2021/2022. The results obtained revealed that, microclimate was modified at a distance up to 11–13 times the windbreak height from the windbreak. Wind speed was more than halved close to the windbreak then the effect began to decrease as we moved away from the leeward side. Air temperature and relative humidity were increased and soil temperature decreased compared to unprotected areas. So, this improvement in microclimate led to 13-17 % an increase in the percentage of germination, 26-28 % in plant length, 34- 36 % in leaf area, 4-4.5 % in total chlorophyll content, and 8-10 % in yield of all tested quinoa genotypes. From the obtained results it could be recommend that the use of windbreaks is very important to improve microclimate, seed germination, productivity and yield of quinoa plants under aeolian deposits conditions. | ||||
