| Abstract:
The experiment was carried out at the CHES Vejalpur farm with pomegranate ‘Ganesh’ grown under rainfed conditions. The climate of the area is semi-arid with mean rainfall of 750 mm, during the experimental period. The mean maximum temperature of the area was 44ºC and mean minimum was 10ºC. The depth of the soil ranged from 0.75 to 1 m, with a pH range of 7.5 to 8.1. The soil of the area is saline in nature. The crop was raised at 5×5 m spacing (400 plants/ha). Root distribution acts as a guide for application of fertilizers as well as irrigation. Root distribution varies according to the type of soil, method of propagation. No such work was carried out in India on pomegranate. Therefore studies were initiated to study root distribution pattern of air layered six-year-old pomegranate ‘Ganesh’. The root distribution pattern in air layers of pomegranate ‘Ganesh’ under semi-arid rainfed conditions revealed that the root system is shallow in nature as below 60 cm soil depth not much root activity was recorded. Maximum root activity on fresh and dry wt. basis was observed in 0-30 cm radial distance from tree trunk (54.17%), which was 31.12% in 30-60 cm radial distance and 2.12% in 60-90 cm radial distance. However, soil depth wise it was maximum at 30-60 cm and 42.69% at 0-30 cm depth. It was least (3.74%) at 60-90 cm depth. | |
