%X The aim of the present study was to evaluate the performance
of Napier cultivars in terms of forage yield, plant morphology and nutrient
contents under two different agro-ecology and geo-topographic conditions. Three
Napier cultivars being conserved by Bangladesh Livestock Research Institute
(BLRI), namely-BLRI-Napier 1,
(BN-1), BLRI-Napier 3
(BN-3) and Merkeron (BN-5) were selected to cultivate in severe drought prone
areas (called Barind) and non-drought area at Savar (Modhupur terrace). Stem
cuttings were planted in rows apart from 70 cm and 35cm spacing between plants.
Data of 6 consecutive harvests from a period of approximately one year were
collected and analyzed statistically by ¡°R¡± software. The results showed that
cultivar and location had a significant (P < 0.001) effect on biomass yield, plant height and
leaf-stem ratio (LSR), while number of tillers were significantly varied with
locations. BN-3 yielded the highest biomass (33.32 t/ha/harvest) at non-drought
location (42.98 t/ha/harvest). The highest plant height was obtained in BN-1
(171.2 cm) at non-drought location (174.6 cm). Number of tillers per hill ranged from 25.4
to 26.3 among cultivars (P > 0.05) and the highest tillers were found at
non-drought location (28.1 no). The best LSR was estimated from BN-5 (0.86) at
drought location (0.95). The proximate analysis showed that CP, ADF and NDF in
whole plant were varied significantly (P < 0.001), being the highest contents in BN-1
(10.69%, 46.20% and 54.58%, respectively). On the other hand, DM and ash
contents did not differ significantly (P > 0.05) among cultivars which
ranged from 15.80% to 17.13% and 13.10% to 14.58%, respectively. The highest CP
content in whole plant was obtained at non-drought location (11.89%), while the
lowest ash (10.57%) and NDF (52.71%) contents were obtained at the same
location. The highest CP contents in leaf were found at non-drought (15.03%)
and the lowest ash (9.86%) at the same location. The highest CP contents
(5.90%) in stem were found at non-drought location, while the
