Other claims from this paper (14)
- Intervention effect High Ca (300 mg L -1) increased tomato fruit yield compared with low Ca (150 mg L -1).
- Intervention effect High Ca (300 mg L -1) reduced the incidence of blossom-end rot in tomato compared with low Ca.
- Intervention effect High Ca (300 mg L -1) reduced fruit russeting in tomato compared with low Ca.
- Intervention effect High Ca reduced tomato fruit firmness compared with low Ca.
- Intervention effect High Ca did not affect tomato fruit size or leaf photosynthesis.
- Intervention effect Tomato plants grown at 20 mg L -1 Mg started to show leaf chlorosis.
- Observation Tomato leaves with moderate chlorosis lost about 50% of their photosynthetic capacity.
- Intervention effect Mg at 20 mg L -1 decreased tomato fruit yield in the late growth stage.
- Association Blossom-end rot incidence in tomato increased linearly with Mg concentration in the early growth stage at low Ca.
- Association Tomato fruit firmness increased with Mg concentration at low Ca.
- Intervention effect At high Ca, late in the season, tomato fruit firmness was higher at 80 mg L -1 Mg than at 50 mg L -1 Mg.
- Intervention effect Fruit russeting in mid-season was least at 300/50 mg L -1 Ca/Mg.
- Recommendation The optimum Ca/Mg concentration for tomato production is estimated at 300/50–80 mg L -1.
- Recommendation Mg may be started at 50 mg L -1 and gradually increased to 80 mg L -1 towards the end of the season in tomato.
