Other claims from this paper (13)

Intervention effect Dry weight of plants and fruit yield of solanaceous fruit vegetables were highest under the 7 NO3-N: 3 NH4-N ratio.
Intervention effect A higher NH4-N ratio severely inhibited growth and fruit development of solanaceous fruit vegetables compared with the 7:3 ratio.
Intervention effect A higher NH4-N ratio markedly enhanced NH4-N and soluble organic N in all plant tissues of solanaceous fruit vegetables.
Intervention effect A higher NH4-N ratio reduced insoluble N and the ratio of insoluble N to total N in solanaceous fruit vegetables.
Intervention effect A higher NH4-N ratio reduced starch content in all plant tissues of solanaceous fruit vegetables.
Intervention effect A higher NH4-N ratio reduced soluble sugar content in the stem and root of solanaceous fruit vegetables.
Association Eggplant had higher soluble sugar and starch contents in the leaf, stem and root than other crops.
Intervention effect Under a higher NH4-N ratio, blossom-end rot incidence was observed in tomato and sweet pepper, with very few incidences in eggplant.
Intervention effect P content in all plant tissues of solanaceous fruit vegetables increased as the NH4-N ratio increased.
Intervention effect Under a higher NH4-N ratio, K, Ca and Mg decreased in solanaceous fruit vegetables, particularly.
Intervention effect Under a higher NH4-N ratio, Fe, Mn and Cu decreased in solanaceous fruit vegetables.
Intervention effect Under a higher NH4-N ratio, Zn decreased in solanaceous fruit vegetables.
Intervention effect Mineral uptake of tomato was more remarkably impaired than that of eggplant and sweet pepper under a higher NH4-N ratio.

G.E. Wilcox; J.R. Magalhaes; F.L.I.M. Silva Journal of Plant Nutrition 1985. doi:10.1080/01904168509363401

Other claims from this paper (6)

Intervention effect NH4 at 112 ppm N caused ammonium toxicity symptoms in tomato
Intervention effect NH4 at 14 ppm N gave slightly higher tomato dry weight than NO3 at the same concentration
Intervention effect Tomato plants supplied NH4 at 14 ppm N appeared normal
Intervention effect Plant growth, K and Ca contents decreased as NH4 concentration increased from 14 to 112 ppm N
Intervention effect Mg contents of tomato decreased as NH4 concentration increased from 14 to 112 ppm N
Intervention effect Soluble NH4 in tomato tissue was greatly increased as NH4 concentration increased from 14 to 112 ppm N

Other claims from this paper (7)

Intervention effect Increasing irrigation frequency from one to three irrigations per day significantly increased dry matter yield in tomato.
Intervention effect Increasing irrigation frequency decreased fresh fruit yield in tomato.
Intervention effect A seasonal application of 620 mm did not increase dry fruit yield compared with 320 mm, both applied as one irrigation per day.
Intervention effect A seasonal application of 620 mm increased fresh fruit yield by a factor of 1.46 compared with 320 mm.
Observation Root weight declined at the time of fruit filling under once-a-day irrigation.
Intervention effect Irrigating three times a day produced a greater final dry matter yield.
Observation After the rapid fruit filling period, all treatments had a period of slow dry matter production followed by an enhanced production rate.
