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., F0: N0P0K0; F1: N75P25K75; F2: N100P37.5K100; F3:N125P50K125; F4:N150P62.5K150 and F5:N175P75K175 (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 N175P75K175 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 N175P75K175 recorded 33.28 t ha-1 followed by N100P37.5K100 (30.26 t ha-1)
