Effect of the Use of Two Calcium Compounds in Fertigation on the Nutritional State and Incidence of Apical Necrosis in the Tomato Plant Under Saline Conditions

May 1997

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)

A low athmospheric humidity, the stomata close and transpiration decreases. This adaptation produces a reduction in the net photosynthesis an increases in photorespiration and depletion of the plants macro and micronutrients as a consequence of the uptake reduction which has a negative effect on the final yield of the crop

The related literature describes the absorption of amino acids by leaves and/or roots in normal situations and in special circumstances, the osmosis-regulating role of Arg, Asn and Gln in hypertonic media, and the accumulation of certain amino acids in situations of climate stress
