Abstract: | Summary The effects of nitrogen and phosphorus on seed yield and seed nutrient content inPisum sativum L. cv Sprite were studied. In the first experiment (spring-sown) seed yield was increased by 55% due to the combined effect of high nitrogen and phosphorus, although in subsequent experiments (during the summer) nitrogen had no effect on seed yield, and a response to phosphorus was obtained in only one of two experiments. In all experiments, increased plant nitrogen and phosphorus supply resulted in increased concentration of the respective element in the seed. |
