- Abstract
When it comes to popcorn, Brazil is the second largest producer of this type of maze. The lack of specific agronomic recommendations for the crop has been a limiting factor in the advance on the cultivation areas. Therefore, the need to carry out studies aimed at the best management for the culture of popcorn is essential. Thus, this study aimed at evaluating the impact of the plant population on some morphological variables and on the final grain yield of two popcorn hybrids (8203 and 4512). The populations of 60,000; 65,000; 70,000; 75,000; and 80,000 plants per ha-1 were studied in the 0.45-cm spacing between sowing lines. The experiment was carried out in the 2018/2019 agricultural year in the experimental area of the Department of Agricultural and Environmental Sciences at the Federal University of Santa Maria, in the Frederico Westphalen campus, state of Rio Grande do Sul, in Brazil, in a randomized block design in a (2x5) factorial scheme. The stem diameter, ear length and weight of a thousand seeds decreased as the plant population increased. For both hybrids, and for most of the variables analyzed, population densities did not significantly affect the final grain yield of popcorn. However, when working with the average population, a superiority of the 8203 hybrid is observed for the variables plant height, height of ear insertion, prolificacy, stuffing, ear diameter, number of grains per ear, weight of a thousand seeds, and final grain productivity.
