'On-farm' seed priming, in which seeds are soaked in water before sowing, results in yield increases of, on average, 30% and has already been adopted by thousands of resource-poor farmers for many crops in many countries in both Asia and Africa. Recent PSP-funded research has shown that seed priming can be used to further increase yield by as much as 90% by overcoming soil micro- and macro-nutrient deficiencies and improving disease resistance.
