Determination of root distribution in pomegranate by root excavation technique

Distribution of various types of roots at different radial distances and depths was studied using the root excavation technique in four year old pomegranate trees. The distribution of root pattern was influenced by the distance from tree trunk, soil depth and the season of excavation. It was recorded that root density was found maximum at nearest radial distance from tree trunk i.e. 0–60 cm (83.77% and 83.29% during post rainy and spring season, respectively) and an increase in distance from the tree trunk resulted in reduction of root density considerably. During post rainy season, roots were found maximum at 0 to 25 cm followed by 25 to 50 cm and 50 to 75 cm soil depths. Same results obtained in spring season. The feeder roots were recorded higher in post rainy season compare to spring season.
