As part of a long-term study on drip fertigation initiated
in 1996, the root distribution of arecanut was examined in
April-May 2005 in 50% NPK, 75% NPK and 100% NPK
fertigation at 10 days interval, 100% NPK soil application
with drip irrigation, basin and sprinkler irrigation methods.
Horizontal spread of root system was more in drip
fertigation (135-144 cm), while it was only 121 em in case
of sprinkler and basin methods. Rooting depth was also
more in drip fertigation (101-136 cm) than in basin and
sprinkler method (77-78 cm). Drip fertigation resulted in
production of higher fine root biomass (34-43%) than drip
+ 1000/0 NPK soil application (33%), basin (22%) and
sprinkler irrigation (21%). Maximum distribution of roots
both fine and thick was noticed with in 50 em radius from
the base of the palm and decreased at 50-100 em distance
and depth in all the treatments. The weight density of both
fine and thick roots was more along dripping plane than
along non-dripping plane at 0-50 em soil depth. With
increase in distance from the base of the palm, the root
weight density decreased. The extent of decrease was more
with basin irrigation, followed by sprinkler irrigation
compared to drip fertigation.
