Abstract

In Congo Brazzaville, tomato cultivation is preferentially carried out by market gardeners during non-rainfall periods in order to curb productive constraints, particularly heavy rains resulting in high parasitic pressure. Indeed the rain disturbs the fruit set and this cause the fall of production of the tomato. This study was conducted to evaluate the productive potential of tomato grafted on African eggplants because of their dense root systems increasing the sap flow of the graft. The experimental design used was in completely random blocks with four replicates for one factor (rootstock) and four treatments (ungrafted tomato, tomato grafted on Diablette, tomato grafted on Bissukulu, tomato grafted on Nkeka). The results demonstrated the compatibility of African eggplant rootstocks Diablette, Nkéka and Bissukulu with the ninja tomato graft. Indeed, the ninja tomato grafted on these eggplants has an average yield of 8.870kg / m² or 3.737kg more than non-grafted subjects with 5.133kg / m².
