Field experiment conducted during kharif- 1999 at MARS, Dharwad revealed that higher tuber yield (12.21 t/ha) was recorded with narrow row spacing (45cm) although more number of A-grade tubers were recorded with wider row spacing.  Planting on June 3rd week recorded significantly highest total tuber yield (12.76 t/ha).  A, B and C grade tuber yield was highest when potato was planted on June 3rd week.  Nitrogen significantly increased tuber number and weight per plant.  Total and different grade tuber yield increased up to 150 kg N per ha (15.68 t/ha).  Interaction effects of row spacing, planting dates and N were not significant.  However net income (Rs.41906/ha and B:C ratio of 2.84  was higher with treatment combination of June 3rd week planting with 45 cm row spacing supplied with 150 kg N per ha.
