Abstract A field trail was conducted during winter season of 2014–15 at Horticultural Research Station, Najanad farm, Ooty on acid soil under irrigated condition to find suitable Nutripellet Pack placement method for potato cultivar Kufri joyti. Nutripellet Pack is a packet in tubular form having several inputs viz., fertilizers, enriched vermicompost, and bioinoculants. The effect of application of nutrients on the yield of potato tuber was evaluated in treatments viz., Surface broad casting, Nutripellet pack at 75% NPK, Nutripellet Pack at 100% NPK, Nutripellet Pack with (paper wrap), Nutripellet Pack with (double polymer layer and Control (without fertilizer application). Among the treatments surface broadcast of fertilizer recorded 26.1 t ha−1 tuber yield. In the case of Nutripellet Pack with (paper wrap) 29.0 t ha1 recorded the highest tuber yield, Nutripellet pack with (double polymer layer) recorded 21.3 t ha−1and Nutripellet Pack with (single polymer layer) recorded 22.8 t ha−1. Nutripellet Packs are having controlled release characteristics in soil for one time placement. Hence, Nutripellet placementhaving paper wrapcould be preferred for potato tuber yield, to save labour, reduce fertilizer cost, increase yield and nutrient use efficiency.
