EFFECTS OF NH4 +–N/NO3 −–N RATIOS ON PHOTOSYNTHETIC CHARACTERISTICS, DRY MATTER YIELD AND NITRATE CONCENTRATION OF SPINACH

Most plants prefer nitrate (NO3 −–N) to ammonium (NH4 +–N). However, high NO3 −–N in soil and water systems is a cause of concern for human health and the environment. Replacing NO3 −–N in plant nutrition regimes with an appropriate amount of NH4 +–N may alleviate these concerns. The purpose of this...
