The experiment "Behavior of agronomic and yield components under increasing dose of chicken in Allium strain L. var. agregatum "regional onion", in Zungarococha-Loreto. 2021", was held at the facilities of the Workshop on Teaching and Research of Horticultural Plants (TEIPH), of the Faculty of Agronomy-UNAP, located at Km. 3 of the road to Zungarococha. The type of research was experimental, explanatory with one independent variable (increasing dose of chicken) and nine dependent variables (plant height, plant diameter, number of leaves/plant, leaf/plant weight, bulb diameter, total plant weight, number of bulbs/plant, weight of bulbs/plant and weight of bulbs/ha). The objective of the research work was to determine the behavior of the agronomic and yield components under increasing dose of chicken in Allium strain L. var agregatum "regional onion", in Zungarococha-Loreto. 2021.
