Other claims from this paper (8)
- Intervention effect Red tomato yields did not differ significantly between nitrate and ammonium feeding.
- Intervention effect Nitrogen rates above 750 mg N plant –1 week –1 did not significantly increase marketable fruit yield.
- Intervention effect Nitrogen rates above 750 mg N plant –1 week –1 enhanced shoot biomass.
- Intervention effect Ammonium-dominated treatments with high chloride showed increasing blossom-end-rot incidence.
- Intervention effect Organic nitrogen produced lower shoot biomass than inorganic nitrogen.
- Intervention effect Organic nitrogen produced lower yields than inorganic nitrogen.
- Observation Organic nitrogen yielded good fruit quality with few blossom-end-rot-infected fruits.
- Recommendation Below 750 mg N plant –1 week –1, ammonium can serve as an equivalent nitrogen source to nitrate for marketable fruit yield.
