Abstract
Intensive production of tomato (Solanum lycopersicum), and the possible diseases in the soil have as a result the reduction in the production.
One way to avoid those problems is the use of the graft, which prevents diseases as Fusarium oxysporum, Pyrenochaeta lycopersici, Verticillium dahliae and nematodes (Meloidogyne spp.). The prohibition of the use of methyl bromide achieves that the graft technique is revaluated, which, as it can provide other advantages in the production of vegetables.
This trial was conducted in a typical raspa and amagado greenhouse structure at Almería, Spain, on artificial cover soil, studying the effects of the commercial rootstocks Beaufort, Brigeor, Heman and Popeye, on yields of four tomato cultivars in the south-east of Spain.
Out of four cultivars tested, Pitenza and Ikram are cluster-type tomato and ripe in a short period of time; and Daniela and Eldiez are loose-type and long shelf life cultivars.
The average yields was 10.73 kgm-2 in the cluster-type cultivars and 12.23 kgm-2 in the loose type cultivars, establishing that the selection of rootstocks didnt provide any significant effect on the total production in the tested conditions.
Therefore, we can say that the choice of a specific rootstock is a decision to be taken according to the problems of soil and the economic effect on the total cost of the crop.
