Abstract: A field experiment was conducted at Regional Centre of Central Tuber Crops Research Institute, Bhubaneswar for consecutive two years (2011 and 2012) to study the collar rot incidence under varied fertility levels and its influence on tuber yield. The highest collar rot incidence was noticed in the treatment T7 (16.11%) viz. FYM 10 t ha-1 + 100-60-100 N-P2O5-K20 kg ha-1 and least was recorded in the treatment T8 (10.59%) viz. FYM @ 25 t ha-1. The former treatment also recorded significantly more corm yield, thus justifying integrated use of FYM and fertilizer. Sole application of FYM @ 25 t ha-1 produced 36.1 t ha-1 which was at par with the other mentioned treatment (37.65 t ha-1). The treatments comprising of only NPK fertilizers viz. 80-60-80 N-P2O5-K20 kg ha-1 (T3) and 100-60-100 N-P2O5-K20 kg ha-1 (T4) also recorded significantly more yield over control.
