Peanut (Arachis hypogaea L.) is a leguminous plant of great agricultural and economic importance that can be used as a primary crop or as a source of several food products.China is one of the major peanut producers with the highest total yield of peanut in the world.Double seed sowing (two seeds per hole) is the dominant sowing pattern of peanut in China,but within-hole competition of two plants limits their growth and yield formation.Single seed sowing (one seed per hole) may be an alternative to solve the problem.The objective of this study is to determine if single seed sowing yielded better than double seed sowing.
