The objective of this work was to carry out a financial profitability analysis of truck farmings especially those of cabbages of China and headed cabbages in Lubumbashi in order to encourage the truck farmers to invest in these cultivations. The studied parameters relate to the socio demography, the production costs, the surface, the output, selling the prices, the incomes and the profit margins. The results showed that there are 86, 7% women in the production of cabbage of China and 53% men for headed cabbage. The main production cost of cabbage returns to the agricultural inputs, respectively 78% and 84,5% for cabbage of China and headed cabbage. The occasional paid labour presents 22% and 15,5% successively for cabbage of China and headed cabbage. On a surface of 15m2, the headed cabbage generates a benefit of 23,1±2,4 $ whereas the cabbage of China gives 13,6±1,7 $ of it. Each dollar invested for cabbage of China and headed cabbage brings back respectively 2,3 and 2,7$. The headed cabbage appears profitable because it translates a financial rate of profitability of 275% ˃230,5% for cabbage of China. Nevertheless; the possibility of producing cabbage of China 3 or 4 times a year makes it competitive. The limit of this study is that we cannot assess land cost, cost of agricultural materials and family labour because of the phenomenon of mutual aid at the truck farmers
