Abstract
An experiment was conducted with different NPK fertilizer combinations to explore the
possibility of improving growth and productivity of popular elephant foot yam (EFY) varieties
of Arunachal Pradesh. Two varieties, Gajendra and TRCB-1 were planted in main plot and
fertilizer combinations viz., F 0
: N 0
P 0 K0 ; F 1 : N 75 P25 K 75 ; F 2 : N 100 P 37.5 K100 ; F 3 :N 125 P 50 K 125 ; F 4
:N 150 P62.5 K 150
and F5 :N 175 P 75 K 175 (kg ha -1 ) were applied in sub plots. The growth and yield attributes were the
highest with Gajendra variety of elephant foot yam with the application of N175 P 75 K 175 kg ha -1
Similarly, higher yield was recorded by Gajendra (29.02 t ha -1 ) followed by TRCB-1 (22.73 t ha -1 ).
Among the fertilizer combinations N 175 P 75 K 175 recorded 33.28 t ha -1 followed by N 100 P 37.5 K 100
(30.26 t ha-1 ).
