Two field trials were carried out in Shandweel Agriculture Research Station, Sohag, Governorate during 2015/2016 and 2016/2017 seasons. This study aimed to investigate the effect of intercropping some garlic varieties in pea varieties field under different garlic planting densities in relation to yield and yield components of both crops. The treatments in which the two varieties of peas and garlic were grown alone individually gave the highest values ​​obtained for most of the vegetative characters, yield and its components. during the two seasons. Intercropping with density of two rows of garlic significantly exceeded the treatments in which garlic was intercropping with a density of one row. Land equivalent ratio (LER) values were greater than one by all intercropping treatments of pea with garlic, in both seasons. Pea₂+two rows garlic₂ gave the highest values of relative crowding coefficient, while pea₁+one row garlic₁ gave the lowest values. The intercropping of garlic on the peas led to a decrease in the number of pods infected with E. zinckenella compared to the solo peas plantation for both seasons of agriculture for all varieties. While, the intercropping led to increase the count of thrips on garlic during the intercropping period, the numbers decreased after the peas were removed. Through this study it can be recommended to intercropping garlic, variety Sids-40, at a density of two rows cultivation on the pea of cultivar Intsar 2, to obtain the highest yield compared to other treatments of intercropping.
