- Abstract
When it comes to popcorn, Brazil is the second largest producer, but still needing imports to supply the country's domestic demand, given the importance of studies that better explore agronomic recommendations for popcorn culture. Thus, the aim of the present study was to evaluate the impact of the plant population on some morphological variables and the final consumption of two hybrid popcorn kernels (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 0.45cm spacing between sowing lines. The experiment was carried out in the agricultural year 2018/2019, in the experimental area of the Department of Agricultural and Environmental Sciences of the Federal University of Santa Maria, Frederico Westphalen campus - RS, in a randomized block design in a factorial scheme (2x5). 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 productivity of grain.
