摘要

The effectiveness of 'on-farm' seed priming ― soaking seeds in water before surface drying and sowing them ― is discussed with reference to published accounts and data from three case studies. Collaboration since 1998 between researchers and more than 900 farmers in Cameroon, Gambia, Ghana, Nigeria and Sierra Leone demonstrated that priming upland rice seeds before sowing resulted in consistent yield benefits, with advantages averaging about 40% across years and sites. In Pakistan, a combination of on-station and on-farm, participatory research over three years showed that priming maize seed for 16 hours before sowing resulted in an average yield gain of about 35%. Similar average yield increases of 40% were reported over three years for primed chickpea in Bangladesh. Data from 253 on-farm trials of chickpea in Bangladesh and Nepal were used to calculate the risk associated with seed priming, which was found to be negligible. Priming seeds of many crops overnight (for 8―10 hours) is effective in speeding up seedling emergence, promoting better stand establishment, more vigorous growth and higher yields. This low-cost, low-risk practice should be promoted more widely using proven farmer-participatory approaches.
