Study of a co-culture tomato / Datura model ( Solanum lycopersicum L. - Datura stramonium L.) in plain field

摘要

The Co-cultivation associates small plants (usually solanaceous) and large-sized plants. There is every reason to believe that co-culture can double production per unit area and work, although no systematic research has confirmed this. Our study is based on this hypothesis; during 2012, an experimental protocol has been set up, on the whole one variety of tomato "TIZIRI" is implanted in association with Datura stramonium L as intercropping, The objective of this trial is to study the evolution of cultivars but also in a biological way without using chemicals products, and the identification of diseases due to insect attacks on the crop. And also to evaluate the production of tomatoes. Some agronomic parameters, in this case the number and size of the fruits, cumulative production, were studied. concerning the production, this technique of co-culture has made it possible to improve the total yield of the tomato, and to reduce the rate of insect and other disease-induced insect attacks, Up to 87.01%, the number of fruits per plant is of the order of 12 fruits per plant, our test provided other information concerning the alleopathic effect, in these plots tomatoes Datura contained less weeds as well as testing the most suitable tomato and Datura cultivars for intercropping and determining best Crop protection, weed control and predator control.
