The cat tail (Typha elephantina), a non-food
commercial crop grows as an emergent hydrophyte in tidal
waterlogged areas. Its leaves are used for preparing mats
and used as roof top and wall partition. Typha sp. has been
found to be efficient accumulator of N from sediment under
waterlogged condition. The N utilization mainly through
nitrate reductase (NR) activity was studied in Typha with
four levels of N fertilizers i.e. 0, 30 and 60 and 90 kg ha-1
applied at three stages of plant growth i.e. basal, 3 and
6 month after planting. In general, there was reduction in
NR activity under waterlogged condition in Typha. But
application of @ 90 kg ha-1 maintained high NR activity
when it was applied as basal stage. Basal application of N
was found better than its application at 3 or 6 month stage
of crop growth. The higher leaf NR activity at 60 and
90 kg ha-1 N application level suggested better N utilization
under waterlogged environment. The photosynthesis
rate showed significant increase with higher N application
concomitant with greater stomatal conductance
(r = 0.84* * ; n = 12). There was significant increase in
leaf yield when N was applied @ 90 kg ha-1 N level as
basal dosage as compared to later stage (3 or 6 months) of
crop growth. The highest fertilizer use efficiency (kg dry
leaf kg-1 applied N) was also found at 90 kg N ha-1 as
compared to 30 or 60 kg ha-1 N level, which corroborated
superior N fertilizer utilization ability of Typha under
waterlogged condition.
