Planted two rows of International Kidney, Majestic and Pink Fir Apple
potatoes, 5 potatoes per row.
International Kidney (Early Maincrop)
Year: 1879. This is the variety sold as 'Jersey Royal'. Waxy. Susceptible to
potato cyst nematode.
Year: 1911. Most widely grown commercial variety in England until the 1960s.
Susceptible to potato cyst nematode. Average resistance to spraing virus
(tobacco rattle virus), common scab and blight. Good yield.
Pink Fir Apple (Late Maincrop)
Year 1850. Waxy. Susceptible to potato cyst nematode.
The picture to the right shows how I have planted the
potatoes. I dug a trench 15cm deep and then broke up the 15cm at the bottom
and mixed it with grass cuttings. This is an attempt to reduce the effects
of scab, which is supposed to attack the grass rather than the potato. Then
I sprinkled calcified seaweed and then covered it over with 10cm of garden
compost. Within the compost I placed the seed potato making sure there was a
light covering of compost. I then filled in the trench with the soil that I
had dug out.
I have dug two trenches 75cm apart and for earlies I space the potatoes 20cm
apart; for maincrop I space the potatoes 30cm apart.
