Objectif
To provide crop and cultivar-specific parameters for seed soaking (safe limits etc) of sorghum, pearl millet, maize, upland rice and cotton and test the practicability of the technique in on-station trials and in farmer’s fields in Zimbabwe and India

Descriptif
In many semi-arid areas establishment of rainfed crops is poor, even when sown under optimal conditions, emergence and early growth of seedlings can be adversely affected if hot, dry conditions follow planting. Previous work in Botswana on Sorghum has shown that controlled pre-soaking of seed (seed priming) before sowing can speed up the germination process and allow establishment to tkae place before the seedbed dries out. Preliminary field evaluation has shown that this is a robust, farmer-friendly low-cost technology.
