Flowering Periods, Seed Yield Components, Seed Quality, and Patterns of Seed Shattering in : Effect of Taxonomy and Nitrogen Fertilization.

Perennial warm-season grasses typically have reduced seed yield, making it essential to identify the critical seed yield components. An induced increase in nitrogen could help determine which components are most limiting. This research aimed to estimate seed yield components in ; evaluate N fertilization effects on the reproductive phase, seed yield components, and seed quality; and establish the pattern of seed shattering over time.

Structural and Morphogenetic Characteristics in : Responses to Nitrogen Fertilization, Season, and Genotype.

Understanding leaf generation dynamics, their seasonal changes, and their responses to nitrogen fertilization (NF) is key to improving pasture utilization efficiency. The objectives of this research were to determine structural and morphogenetic variables underlying changes in herbage mass on a set of genotypes. Ten genotypes were evaluated in experimental plots following a completely randomized block design under a split-plot arrangement for two N-rates during four periods.
