Produção e desenvolvimento do coentro submetido a diferentes doses de urina de vaca

Abstract

This study aimed to evaluate the influence of cow urine at different doses on the production and development of coriander (Coriandrum sativum L.). The experiment was conducted to verify the effects of this organic input on plant growth and weight. During the experiment, the plants were subjected to different treatments, with some plants receiving low amounts of cow urine, while others were subjected to higher doses. The doses applied were T0: 0ml; T1: 20ml; T2: 40ml; T3: 60ml; T4: 80ml; T5: 100ml; allowing for the evaluation of the gradual effect of cow urine on crop development. From the implementation of the study, it was possible to monitor plant growth over the weeks, recording plant height. This monitoring was carried out systematically, with weekly measurements taken to assess the impact of different dosages on vegetative development. Furthermore, at the end of the experimental cycle, the plants were harvested, followed by the measurement of the natural and dry mass of the aerial part and roots of the coriander. This data was analyzed to determine the efficiency of each dosage in promoting healthy and productive coriander growth. The experimental approach allowed the identification of clear trends in plant behavior in response to variations in urine doses, providing valuable information on the suitability of this input in agricultural management. The results obtained demonstrated that the use of cow urine as fertilizer is a viable and sustainable alternative for coriander production, provided it is applied in appropriate doses. The research highlighted the importance of adjusting the quantities to avoid possible adverse effects, such as excess nutrients or deficiency of essential components. It was observed that certain dosages promoted more vigorous growth and a greater final weight of the plants, which reinforces the potential of this organic input as a fertilizer. The study contributes significantly to expanding knowledge about sustainable agricultural practices, especially in the context of horticulture. Using cow urine as fertilizer not only reduces dependence on chemical fertilizers but also promotes nutrient recycling, aligning with the principles of the circular economy. Furthermore, the results can serve as a basis for new research focused on the application of organic inputs in other economically important crops.
