Abstract
Different placements and rates of P fertilizer were applied to field pea (Pisum sativum) to determine which had the greatest effect on N-fixation, germination and nodulation. Phosphorus fertilizer was provided as monoammonium phosphate (MAP) and triple superphosphate (TSP). Fertilizer was either seed-placed (SP) or side-banded (SB). It was found that there were no negative effects on germination or nodulation and MAP which was seed-placed at a rate of 20 lb acˉ¹ had the greatest significant effect on N-fixation.
