Effect of Planting Dates and Varieties on Potato Yield

There is a huge gap in the demand and production of potato in the state of Odisha. One of the main causes of low potato productivity in the state is the short and mild winter during the growing period. Late showing and improper choice of varieties make the problem many folds. In the present experiment with five planting dates and four varieties, 15th November emerged as the best planting date with a maximum tuber yield of 24.019 t ha-1. Kufri Pukhraj was found to be the best variety with 24.426 t ha-1 tuber yield. This variety when planted on 25th of October resulted in both highest net return of Rs. 80073/- ha-1 and B: C ratio of 2.23. Late planting of 5th December in Kufri Chandramukhi resulted in a negative net return of Rs. 2933/- ha-1.
