Using the grafting against soil parasites of solanaceae
In Algeria vegetables crops growing under greenhouses are dominated by Solanaceae. These crops are attaqued by various diseases and parasites (pests) particularly the nematodes. The use of chemicals is very expensive for the farmer in the developing countries. In addition, theses chemicals represents a real danger for the soil and environment by their residues. In our study ,we have tested the influence of grafted tomatoes on the population of nematodes and quality of tomato production grown under greenhouse. Two varieties of tomato grown in a highly infected soil by nematodes., the first resisting one called « tresor » the second sensitive called « Lucy », the third treatment : sensitive grafted on the resisting varieties one . The grafting technique is terminal cleft part. Obtained results show a rate of success of 93,91 %. Grafting caused a loss of precocity of 14 days. The total production was important in the grafted plants and in the resisting ones compared to the sensitive ones .Grafting does not seem to have an influence on the vitamin C. At the end, grafting decreases clearly the nematodes population in this grown soil.
