Abstract

The application of organic fertilizers to the soil promotes better plant development, encouraging a more favorable growth response. The objective of this study was to evaluate the effect of two organic fertilizers (cow manure and chicken litter) and two irrigation volumes on the growth of tara [Caesalpinia spinosa (Molina) Kuntze]. Stem length, root length, water content, and the physical and chemical properties of the soil, such as pH, electrical conductivity (EC), and texture, were evaluated. The plant response to the organic fertilizers and water volume showed no significant differences in stem size. However, roots showed significant differences, being larger with manure (17.74 cm) and chicken litter (13.89 cm) at irrigation volumes of 100 and 50 mL, respectively. Furthermore, these organic fertilizers significantly improved leaf area compared to the control. The incorporation of these fertilizers also enhanced soil structure
