Abstract

Okra (Abelmoschus esculentus (L.) Moench) is a tropical plant in the Malvaceae family, all parts of which have nutritional and medicinal uses. With a view to improving productivity, a study was conducted in Ouagadougou by Agrostore Production, a company specializing in soilless cultivation in Burkina Faso. The objective was to evaluate the effect of two types of liquid fertilizers on the agro-morphological and physiological parameters of okra in soilless cultivation in greenhouses. The device adopted is a completely randomized block of 4 blocks divided into elementary plots made up of 4 treatments (T0: control, T1: Hydroponic A fertilizer, T2: Hydroponic B fertilizer, and T3: combination of the two fertilizers, Hydroponic A and Hydroponic B). The Amina F1 okra variety was chosen. The cultivation consisted of the creation of a nursery followed by transplanting on substrate in crop bags. Agromorphological and physiological parameters were measured. The results showed that plants fertilized with the combination of the two fertilizers (Hydroponic A + Hydroponic B) had the highest values on all parameters, followed by those fertilized with the Hydroponic B fertilizer. An average of 11± 0.88 fruits per plant were obtained with the two fertilizers combined, 7±1.20 with the Hydroponic B fertilizer, 5±0.99 with the Hydroponic A fertilizer, and 4±0.7 fruits for the control treatment with significant differences (p˂0.001). The yield per hectare is estimated at 9.55±1.19 t/ha for the two fertilizers combined, 6.34 ±0.82 t/ha for the Hydroponic B fertilizer, 4.58±0.48 t/ha for the Hydroponic A fertilizer, and finally 2.58±0.22 t/ha for the controls. In view of these results, the combination of the two fertilizers (Hydroponic A + Hydroponic B) is therefore suitable for the cultivation of okra in soilless cultivation in greenhouses in Burkina Faso.
