Efecto del injerto como herramienta tecnológica en tomate industrial para el aumento de rendimiento en suelos de condiciones sub-óptimas de Cuyo
Cuyo is the most important region for processing tomato cultivation, with about 77% of the national production, and Mendoza province provides about 75% of the products derived from tomatoes (344,000 tons per year of a national total of 436,000 tons, 2017-18 campaign).

| Sumario: | Cuyo is the most important region for processing tomato cultivation, with about 77% of the national production, and Mendoza province provides about 75% of the products derived from tomatoes (344,000 tons per year of a national total of 436,000 tons, 2017-18 campaign). The current challenge is to improve crop productivity to solve problems as the intensive use of soils due to the increase of drip irrigation, whose fixed investment hinders the implementation of land rotation strategies. This drawback has increased the incidence of pests, diseases and decay of yields, given the prohibition of soils biocides (methyl bromide) and other agro-chemicals used in the crop management. Currently, in order to increase yield, different strategies that are environmentally safer are proposed to minimize the risk of the use of agrochemicals and prioritize the environment protection, and also both producers and consumers health. In recent years the use of rootstocks has increased in varieties of tomatoes for fresh consumption, since better yields and a more extensive production cycle are obtained. However, in processing tomato this technology is not common, possibly because of the cost of the grafted seedling, although preliminary results are very promising with an average increase of 35% in the production. This research will be focused on the effect of rootstocks and its compatibility with different commercial or improved varieties, and evaluate agronomic performance, yields and the quality of fruits for their nutritional properties, soluble solids content of great importance for industrial purposes, and beneficial bioactive compounds. The implementation of this technology, adapting plant density and the efficient use of equipment and supplies, will help to improve the production system and the quality of the industrialized products of tomato in different conditions of soil: optimal and suboptimal for intensive use, and for the expansion of cultivation in marginal areas. |
