(2024-08) Albuja Torres, Bryan Mauricio; Zurita Vásquez, José Hernán
These humic substances are known to be stable carbon chains that have various chemical, biological and physical effects on the soil, they can also have positive effects directly on the development of plants. The objective of this research was, “Evaluate sources of humic acids on the physiological response in the formation of rose plants (Rosa sp)”. The effect of humic acids (Biohumic Fill, Pacha Mama) on the physiological response in the formation of rose plants (Rosa sp.) was evaluated. Finished the data collection part of the variables; bud sprouting time, stem length, stem diameter, chlorophyll measurement and nitrogen quantification, in the time span of 30 days, that humic acids fulfilled in the physiological development of the formation of rose plants (Rosa sp.). The experimental work was carried out on the premises of the Faculty of Agricultural Sciences of the Technical University of Ambato, province of Tungurahua, Ecuador. The experimental design of randomized blocks in a 2x3+1 factorial arrangement with three repetitions was used. The Infostat statistical program was used. It was evaluated that the best Humic Acid in the physiological response in the formation of rose plants (Rosa sp) was the Biohumic Fill product with a recommended dose of 5 cc/L.
