Abstract

Creole popcorn maize exists in different parts of the country and has a wide variety, however, there are few recent reports on the morpho-agronomic characteristics of these varieties, requiring further studies to strengthen their conservation and commercial use. The present study aimed to evaluate the morpho-agronomic characteristics of Creole popcorn under different doses of bone meal in Teresina, PI. For this purpose, a purple and pointed Creole variety was tested under local conditions, which was grown under different doses of bone meal. The studied characteristics were plant height at flowering, number of flowering days, ear insertion height and number of ears per plant. The doses showed differences only for the number of ears per plant, with 250 g/m being the most efficient dose
