Objective: To evaluate the phenological development and fruit quality of habaneropepper (Capsicum chinense Jacq.) with three nutrient solutions.Design / Methodology / Approach: In a hydroponic system the nutrient solutionsof Steiner, Hoagland and Soria were used to evaluate the phenology, morphologyand pungency (spicy-hotness) of the habanero pepper fruits.Results: It was observed that the nutrient solution of Soria brought flowering 4 dahead, but it delayed fruiting by 2 d compared to the other treatments. Steinersolution incremented length (4 cm), diameter (2.9 cm), weight (8 g) and moisturecontent (89%) of the fruit compared to the other nutrient solutions. Capsaicin anddihydrocapsaicin increased in plants watered with Steiner nutrient solutions (24and 12.5 mg g -1 , respectively) and Soria (23 and 12.7 mg g -1 , respectively), as wellas Scoville units (> 538,000).Study limitations / Implications: Although favorable results were found in sometreatments, more studies are required to evaluate the nutrient composition of thedifferent organs of habanero pepper plants, by phenological stages.Findings / Conclusions: Considering phenology, fruit quality and capsaicinoidscontent, the Steiner nutrient solution could be a suitable option for cultivatinghabanero peppers in hydroponic systems.
