Aiming to evaluate the productivity and quality of fennel fruits produced in the countryside of Sergipe, with no irrigation, they were evaluated organic crops in Frei Paulo-SE. They were installed crops in 2008 and 2009 from seeds, on beginning rainy time. Seedlings obtained from seeds were transplanted in June 2008 and 2009. Besides, after the last harvest of the plants, grown in 2009, it was done a drastic pruning on plants, on May, 2010. The plants were held on the area until their fruits harvest, on december and January of 2008, 2009 and December 2010. The fennel fruits yield was 720 Kg ha -1 in the first crop (2008) and 349 Kg ha -1 at following crop (2009), while the fruits yield obtained from pruned plants was 589 Kg.ha-1. It is suggested that the higher yield at the first year has been due to the higher average rainfall and its greater availability of water. The observed yield in sprouted plants was higher (at 2010) than fennel yield of 2009. It can be explained as a function of precipitation, likely as a function of greater root development and increased number of branches and umbels after pruning and breaking of apical. These results reveal water availability importance to fennel yield. The dried mass of fruits (5.29 g to 1000 fruits), high content of essential oil in fruits (3.2%) and the essential oil composition reveal good quality of fennel fruits of Sergipe.
