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 .
Effect on Yield and incidence of Blossom-end of Foliar Applying Calcium Products on tomato cultivated in saline conditions
The objective of this study was to determine the effects of two sources of calcium applied by fertigation on the incidence of apical necrosis in tomato crops in saline conditions. The treatments tested were the following: AQ (application of AminoQuelant-Ca), NC (application of Ca(NO3)2) and T (control, with no extra calcium)
