In this practice, the seedlings of pearl millet (Pennisetum typhoides), wheat (Triticum aestivum) and sorghum (Sorghum vulgare) are soaked into salt solution before sowing in the field. This will bring the empty seeds on top of solution which could be easily removed and no empty seeds are used in sowing which gives even sowing and ultimately good yield of the crop.
