This trial was conducted on an experimental plot of the Jean Lorougnon Guédé University in Daloa (Ivory Coast). The experiment was conducted on "the comparison of the effects of organic fertilizers based on Tithonia diversifolia and Thevetianeriifolia on the optimization of growth and yield parameters of lettuce (Lactuca sativa L.)". Four treatments were tested in completely randomized Fisher blocks, with three repetitions. The results obtained on the growth and yield parameters considered were significantly influenced by the treatments applied. Data were collected every seven days for growth parameters and only once for post-harvest yield. Liquid treatments gave the best results on height (12.96 centimeters) with Thevetia, number of leaves (8.91) with Thevetia, width of leaves (5.79 centimeters), length of leaves (8. 10 centimeter) with Tithonia and the wingspan (11.15 centimeter) of the lettuce plants, as well as on the yield. The treatments significantly influenced growth and yield parameters.
