Avaliação da adaptabilidade de cultivares de milheto híbrido em Maringá. Paraná.

Abstract

Originally from Africa, millet Pennisetum glaucum (L), today is widely cultivated in Brazil thanks to genetic improvement, for better adaptation to the types of soil and climate of the country. In turn, millet is used in the production of grains for human and animal consumption, ground cover and as fodder for animal feed. The purpose of this study is to conduct at field level 2 commercial and 3 pre-commercial dual-purpose hybrid millet cultivars in two planting times, with the first planting carried out on 12/22/2020 (first crop) and the second planting day 02/25/2021 (second crop). Therefore, the objective of this research was to evaluate the phenological development, cultivation value and use (VCU), of each cultivar, grain production and adaptability and foclimatic for the region of Maringá - PR. The reference manual for VCU tests of millet from the Bonamigo breeding program (BAM) from ATTO Sementes was used. Therefore, favorable climate adaptability results were obtained with satisfactory development and considerable good yield for the first crop, while the second crop had valid phenological development, but with lower grain yield being unsatisfactory, due to the atypical climate during the development period.
