Verbatim
e1“Tomato plants (Lycopersicon esculentum Mill. cv. Momotaro) were cultured in nutrient solution supplying 35 meq or 50 meq of nitrate (NO3) per plant weekly from the flowering stage of the first truss in two cropping seasons”
e3“In the fall to winter cropping, however, high NO3 supply did not increase the uptake of NO3, but tended to decrease the rate of fruit set and marketable yield”

Other claims from this paper (10)
- Intervention effect High NO3 supply tended to decrease the rate of fruit set and marketable yield of tomato in fall to winter cropping.
- Observation Tomato fruit productivity was high in spring to summer cropping, where almost all supplied NO3 was absorbed.
- Association Accumulation of NO3 in tomato petiole sap was associated with high NO3 supply in fall to winter cropping.
- Association Reduced rate of fruit set and fruit weight of tomato were associated with low NO3 concentration in petiole sap.
- Association Cropping season greatly influenced fruit growth of tomato.
- Association Cropping season greatly influenced the concentration of NO3 in tomato petiole sap.
- Intervention effect High NO3 supply tended to increase potassium concentration in tomato petiole sap.
- Intervention effect High NO3 supply tended to increase electrical conductivity value in tomato petiole sap.
- Intervention effect High NO3 supply tended to decrease phosphate, calcium and magnesium concentrations in tomato petiole sap.
- Association Concentrations of these elements in tomato petiole sap consistently reflected their uptake rates in two cropping seasons.
