Effects of phosphorus and potassium on alfalfa seed quality

摘要：

Previous research showed that potassium increased soybean seed germination rate ( Jeffers et al., 1982 ), while nitrogen and phosphorus decreased hard seed percentage of Egyptian clover (Bagoury and Niyazi,1975).However, the effects of macronutrients fertilization on alfalfa seed quality have not been determined.The experiment was designed to determine the effects of combined application of phosphorus and potassium on alfalfa seed germination and hard seed percentage.
