Mpundu et al., J. Appl. Biosci. 2017 Influence des sols contaminés en cuivre sur le développement de deux variétés (locale et améliorée) de légumes dans la région de Lubumbashi (RD. Congo). 11410Journal of Applied Biosciences 115: 11410-11422 ISSN 1997-5902 Influence des sols contaminés en cuivre sur le développement de deux variétés (locale et améliorée) de légumes dans la région de Lubumbashi (RD. Congo). 11411ABSTRACT Objectives : In the former province of Katanga, subsistence agriculture is predominantly traditional. While these soils are contaminated by industrial effluent, the result is an increase in the number of substances rich in etms (zinc, cobalt, lead, arsenic, copper, cadmium). The objective of this study was to assess the behavior of African carrot and eggplant culture on contaminated soils and to determine the potential risk of food chain contamination by the MTEs in Lubumbashi City. Methodology and results : Four soil types were harvested to install the two crops (African carrot and aubergine).The experiment was carried out in accordance with a factor 4 * 2 apparatus, thus the main factor consisted of two variants of carrot and aubergine (improved variety and local variety) and the secondary factor consisted of 4 soil variants including Kipushi soil, Pengapenga soil, Luwowoshi soil (Ruashi), and Kassapa farm soil. The results showed that the soils of the vegetable gardens of the city of Lubumbashi, as well as the carrot biomasses installed on these soil, showed very high concentrations compared to the established norm, whereas the eggplant biomasses that did not Contamination, regardless of the contamination of the substrates. Conclusion and application of results: Improved varieties of carrots and eggplants from France are well behaved compared to local varieties commonly used by farmers in the city of Lubumbashi, we will advise farmers to use these varieties Provision to avoid the risk of contamination of the food chain and in the next studies that an in situ experimentation is carried out using the same varieties.
