  • Normally soybean needs 3 – 4 irrigation.
  • The first irrigation should be done at the time of sowing or germination stage (Sprouting stage).
  • The second irrigation requirement should be done during flowering and the third irrigation should be done during pod formation (Flowering stage & Pod filling stage).
  • The final irrigation is important when making grain in pods (Grain development stage). Irrigation is more important during making pods and grain development in pods, if there is no water at that time then the production can decrease.
