Green gram

Ready to harvest 60–90 days after planting
Work it takes 60–124 days per hectare, by hand

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 28 Mar 2026. That is the point in the window where the rains are most reliably established.

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

Planting after 24 Sep 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

What decides this in Mbomou

Rain and temperature 96%
The soil 96%
The lie of the land 76%

For green gram in Mbomou, the lie of the land is the tightest of the three at 76%. 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.

Rain in a typical yearAbout 1,266 mm in a typical farming district
Across its districtsFrom about 1,191 mm in the driest of 5 districts to about 1,335 mm in the wettest
This season's rainRain close to usual — plan around about 1,266 mm falling roughly when it always does
This season's heatHotter than usual — about +1.1 °C over the growing months. Heat makes the same rain do less, so a dry spell bites sooner: do not plant late, and shade or mulch what you can.

What it takes to grow green gram in Mbomou

Nitrogen (N)About 56 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag
Phosphate (P₂O₅)About 14 kg per hectare
Potash (K₂O)About 25 kg per hectare
In the shopsA basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. Skip the nitrogen top dressing; inoculated seed does that job.
Hand work60–124 days per hectare, by hand

These are the nutrients a green gram crop of that size carries off the field. What you actually apply depends on what your soil already holds — which is what a soil test, or the app's field records, tell you.
