Context of "Harvest a row of potatoes"
That was your first experience doing Farming in Taskman. Farming is handled differently from all other skills. You can do Farming activities whenever you wish - as long as they only give experience in Farming. As for your potatoes and "time-gating", rule §5 states that if an active task has a time-gate (real-life time must pass), you have to complete as much of the task as you can. If you still cannot proceed, you are allowed to select the time-gate unique in the dropdown and move on. You must return to and finish it as soon as possible. Let's continue on your adventure. But don't forget the potatoes!
