Now, we grow potatoes every year and our potato planting preparations include pre-sprouting (also known as greensprouting) & cutting seed potatoes. These practices encourage early growth, improve yields, and speed up the production of tubers.
Does cutting potatoes increase yield?
The whole seed (T and T1) produced significantly fewer proportions of small size tubers < 50 mm than cut seed tubers (T2 and T3). It seems that cutting the tubers would increase tuber yield. According to Kabir et al. (2004), the whole tubers seeds gave significantly higher yields than cut pieces.
Should I cut my seed potatoes?
If your seed potatoes are especially small, you can plant them whole, but most of the time, seed potatoes should be cut into chunks that have at least two eyes each. Cutting up your seed potatoes helps you make the most of the seeds you have and maximize your crop.

When the potatoes have sprouted and grown foliage about 8” tall, you should begin “hilling” the plants by mounding the fluffy soil on either side of the trenches up around the stems of the plants. As long as there is some foliage sticking out they’ll keep growing, and the more you hill, the more potatoes you’ll get.

What causes low potato yield?
Daytime heating of roots is one reason why potatoes grown in above-ground containers may fail in warm summer climates. Potatoes can take warm air temperatures, but when the roots warm up too, productivity plummets.
When should I stop watering potatoes?
Stop watering your potato plants about 2-3 weeks before harvest, or when you first see the foliage on the plants starting to turn yellow. Make sure to harvest your potatoes on a dry day when the soil is dry—harvesting potatoes when wet or damp can cause the potatoes to rot more easily in storage.
