The application of the different sources of calcium was carried out in the study to both roots and foliage in order to correct apical necrosis in tomatoes grown in saline conditions.
The importance of calcium to the stability, structure and rigidity of the cell wall and membranes has been shown in several vegetable species, as it results in tissues that are firmer and more resistant (Ferguson and Drobak, 1988). There are new calcium-based products that provide greater absorption of the mineral by the plant tissues. Complementing this with an appropriate frequency of application should produce better results than those obtained in previous studies; this would mean firmer ...
In an open-air commercial tomato plantation fertigated with saline water (mean CE of the water used: 5.2 dS m-1), we studied the effect on the incidence of apical necrosis (blossom-end rot) and the nutritional state of the crop when calcium nitrate (CN) and AminoQuelant-Ca (AQ) were added to the irrigation solution .
Leaf application and fertigation with AminoQuelant-Ca and leaf application of EDTA-Ca considerably reduced the incidence of blossom-end rot (BER)
This study evaluated the effect of different leaf treatments carried out with a compound of calcium with amino acids and a calcium chloride standard solution on the mineral content in leaves and fruits, and on several quality parameters. Increased calcium in the fruit was associated with increased hardness and reduced incidence of bitter pit.
