Evaluation of thermophosphate in growth and production the strawberry (Fragaria x ananassa Duch.) cv. ‘Albión’
The strawberry is one of the most important fruits in the world for its multiple industrial, medicinal and culinary uses. In Colombia, the production is concentrated in the departments of Cundinamarca, Antioquia, Norte de Santander, Cauca and Boyacá . Its growth and productivity are determined by an adequate fertilization in elements such as nitrogen (N), potassium (K), calcium (Ca) and phosphorus (P), being P an element of great importance in various physiological processes but with low availability for plants in soils with acidic conditions . For this reason, the aim of this study was to evaluate the effect of an unconventional source of phosphorus (thermophosphate), on the growth and production of strawberry plants cv . ‘Albión’ under conditions of the municipality of Viracachá, Boyacá. A completely randomized experimental design was used, with 4 treatments, which were increasing doses of thermophosphate (0, 300, 600 and 900kg ha-1) with 4 repetitions. The content of total chlorophylls, dry weight of aerial part and root, number of reproductive structures, production and foliar concentration of phosphorus, calcium and silicon were evaluated. There were significant differences (P≤0.05) in the variables total chlorophyll, root dry weight, production by quality, foliar concentration of P, Ca and silicon (Si); the other variables did not show statistical differences. The best results were presented with the treatments of 300 and 600 kg ha-1 of thermophosphate turning it into an alternative supply in soils with acidity problems and low availability of P.
