An experiment was conducted at District seed farm of Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal in the year 2009-11 to study the effect of date of sowing, variety and fertilizer dose on Potato - groundnut cropping sequence in New Alluvial Zone of West Bengal. Varieties viz. Kufri Pukhraj (V1), Kufri Chandramukhi (V2) and Kufri Jyoti (V3) were grown in two dates of sowings (D1 – 18th November and D2 – 28th November in both the year 2009 and 2010) with two fertilizer doses (F1- 200:150:150 kg ha-1 of N: P2O5: K2O, F2-150:125:125 kg ha-1 of N: P2O5: K2O). For the succeeding crop groundnut, 4 levels of fertilizer (FG1: No fertilizer, FG2: 25 % of RDF, FG3: 50% of RDF, FG4: 75% of RDF) doses were tested in the residual soil of potato. The experiment was laid out in split Strip plot design. The two years pooled data of potato in respect of plant stand m‑2 at harvest, no. of tubers plant‑1 and tuber weight plant‑1 were found maximum when planting was done on November 18. But higher single tuber weight was recorded when sowing was delayed till 28th November. Date of sowing does not influenced significantly on tuber yield of various grades. “Kufri Pukhraj” recorded maximum numbers of tuber plant‑1, higher single tuber weight and total tuber weight plant‑1 and consequently the tuber yield. Application of fertilizer doses of 200:150:150 kg ha-1 of N: P2O5: K2O improved plant stand m-2 at harvest, no. of tuber plant‑1 but they remain at par. However increased in fertilizer dose (F2) leads to the increased in tuber weight plant‑1 and also the total tuber yield significantly. Among the levels of fertilizer tested in groundnut, FG50 which received 50 % of recommended dose of fertilizer proved to be the optimum doses of fertilizer as far as Pod yield (kg /ha), haulm yield (kg /ha) and kernel yield is concerned.
