Studies on Production Potentials of Two Varieties of Potato (Kufri Jyoti and Kufri Pukhraj) Produced under Zero Tillage Condition in the Basanti Block, Sundarban Region, West Bengal

Abstract

On-farm trial studies were made at the farmer's field of Joygopalpur Mouza, Jyotishpur G. P., Basanti Block of Sundarban region, West Bengal during the rabi (winter) season of 2013-14 (December 2013 to February 2014) and 2014-15 (December 2014 to February 2015) with liquid fertilizers and also in rabi season of 2015-16 (December 2015 to February 2016) with organic manures to understand the effect of different fertilizer packages as well as the effect of two organic manures like cow dung compost and vermi compost on production potentials of two varieties of potato, viz., Kufri Jyoti and Kufri Pukhraj under zero tillage cultivation condition in the Sundarban region, West Bengal, India. It was revealed that maximum plant height was obtained under T2 treatment followed by T3 treatment in different fertilizer packages while maximum plant height was noted under T4 treatment followed by T2 in case of two organic manures treatments. Like-wise maximum number of tubers per hill was from T2 treatment in different fertilizer packages and maximum number of tubers was encountered from T4 treatment with organic manures. Tuber weight per hill and tuber yield per hectare was recorded highest from T2 treatment and T4 treatment (statistically superior) respectively with chemical fertilizer packages and organic compost cases.
