SUMMARY Fluid drilled germinating lettuce seeds gave earlier production of larger heads than dry sown natural seeds. The addition of sodium phosphate to the gel with germinating seeds increased seedling growth rate which further advanced maturity and increased head weight. Sodium, ammonium and potassium phosphate added to the gel increased seedling dry weight of onions compared to the germinating seed control which produced larger seedlings than dry seed. However, these early improvements in onion seedling size diminished with time.
