Use of biofertilizer from microalgae cultivated in wastewater from cattle farming in the production of coriander (Coriandrum sativum L.)
Chlorella sp., nitrogen, microalgal biomass.
Coriandrum sativum L., popularly known as cilantro, is an annual leafy vegetable native to the eastern Mediterranean that has great socioeconomic value in Brazil, and is cultivated mainly by small and medium-sized producers. Considering that fertilization effectively contributes to a high yield in the production of this vegetable and that the effluents generated by cattle farming can be a source of environmental pollution when not treated properly, this project aims to evaluate the potential use of biofertilizer from microalgae cultivated in cattle farming effluents as an alternative to the use of conventional fertilizers for the production of coriander (Coriandrum sativum L.), cv. Verdão. For this purpose, four different treatments will be applied, including a control group (T1 = 100% NPK), in addition to four groups that will receive different doses of microalgal biofertilizer (T2 = 100%, T3 = 110%, T4 = 120%). The experiment will be conducted in a completely randomized design (CR), with five replicates for each treatment. At the end of the cultivation period, the following morphological parameters will be evaluated in the plants: aerial part height (APA); root length (CR); fresh root mass (MSFR); fresh aerial part mass (MFPA); dry root mass (MSR); dry aerial part mass (MSPA) and aerial part succulence (SCPA). As a result, it is expected that coriander plants cultivated with microalgal biofertilizers will present productivity and growth parameters similar to or superior to those of the plants in the control treatment.
