1. Sowing depth of annual ryegrass seed on different substrates as a vigor test
Resumo: Sementes de azevém com baixa qualidade fisiológica têm resultado em pastagens com inadequado estande de plantas para a cobertura do solo e, sobretudo, para a exploração forrageira. Neste sentido, o presente trabalho teve como objetivo propor um teste de vigor para sementes de azevém anual. Foram testadas profundidades de semeadura (0,5; 1,0; 1,
