Rain-fed. These dates are worked out from each place's own rainfall, for a field watered by the season — with irrigation a window can open earlier, close later, or come round more than once a year. Check your own field under What grows, or get the Divisi app for a calendar dated to your farm.

If you only get one chance to plant, aim for around 9 Jun 2027. That is the point in the window where the rains are most reliably established.

This season's rainfall outlook for Serejeka is close to normal, so these dates match the pattern the area usually follows.

Planting after 18 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

What decides this in Serejeka

Rain and temperature 96%
The soil 96%
The lie of the land 60%

For soybean in Serejeka, the lie of the land is the tightest of the three at 60%. You cannot flatten it, but you can farm it: plant along the contour rather than up and down, ridge or tie ridges to hold water on the slope, and expect shallower rooting than the crop would manage on flat ground.
