Abstract

The results of the field experiments conducted in lateritic acid soils at the College of Agriculture Farm, Sriniketran, Visva Bharti, West Bengal during the rabi seasons of 1979-80 and 1980-81, revealed that a plant density of 100,000 plants per hectare resulted in high level of tuber bulking rate, produced large quantity of medium and big sized tubers which ultimately recorded maximum tuber yield of potato under this short and mild winter condition of West Bengal. Split application of fertilizers (150 kg N, 100 kg P. O, and 100 kg K, O/hat-hait at planting and the other half at 25 days after planting was found beneficial for achieving high rate of tuber bulking, more of larage sized tubers and finally high tuber yield. Kufri Jyoti produced maximum yield (198 g/ha) through large quantity of medium and big sized tubers whlie Kufri Chandramukhi gave an early harvest producing 170 q/ha of potato tubers
