To chit or not to chit potatoes?

As an unapologetic science geek who finds trawling through the data of agricultural trials fascinating, I am forever curious as to whether age-old horticultural techniques are actually supported by good evidence.The argument is that this process artificially elongates the growing season, resulting in an earlier crop and greater yields.However, for home-growers low on space this can mean windowsills covered in egg cartons of shrivelled-looking spuds which, aside from not being exactly ornamental, can take away prime “window front” real estate for growing seedlings.For example, a two-year trial published by the Department for Environment, Food and Rural Affairs in the early 2000s found conflicting results from one year to the next.If, on the other hand, yield doesn’t concern you that much and it is smaller, new spuds you are after in exchange for less work and more windowsill space, ditch the chitting altogether. .
