busy farming season
Refers to the period when agricultural work is at its peak, such as planting or harvest time.
During the busy farming season, we work from early morning until late at night.
This year's busy farming season started earlier than usual.
農閑期 is the slow season when farm work is light, while 農繁期 is the busy season when farmers are fully occupied with fieldwork.
Compound of 農 (agriculture), 繁 (busy, flourishing), and 期 (period, season).
