Abstract
A field experiment was conducted in El-Hammam region, Matrouh Governorate, Egypt. The study examined the impact of different irrigation methods, organic fertilization rates, and their interactions on the yield of cactus pear plants. Four irrigation systems were used: drip irrigation with a single irrigation line for each tree row; drip irrigation with two irrigation lines on both sides of the tree; drip irrigation with rings; and sprinkler irrigation. Four sheep manure rates of 0, 10, 20, and 30 kg/tree were applied. Several growth and fruiting parameters were measured. The results revealed that, sprinkler irrigation was significantly superior to other irrigation methods in terms of fruit production. Increasing manure levels significantly boosted growth, fruit yield, and quality. According to data analysis, maximum significant yield parameters were found when sprinkler irrigation was used in conjunction with sheep manure at the highest level of 30 kg/tree. This treatment resulted in a significant increase in plant height, canopy volume, number of fruits per plant, total yield per plant, juice weight per fruit, fruit T.S.S. percentage, fruit T.S.S./acid ratio, and ascorbic acid content, as well as the lowest fruit total acidity percentage.
