ABSTRACT The objective of this study was to evaluate the associations among forage production related traits in Paspalum nicorae Parodi ecotypes and employ BLUP multi-trait path analysis as a selection criterion. Eighty-four ecotypes were grown in a randomized block experimental design with four replications and measured for three years. Measurements included number of tillers, fresh matter, leaf dry matter, stem dry matter, inflorescence dry matter, total dry matter, leaf:stem ratio, harvest index, cold tolerance, forage persistence, growth habit, and plant […]

The research was carried out in a greenhouse, at the UFRPE, from October 2000 to May, 2001. The objective was to evaluate the effect of phosphatic fertilization and harvest systems on the chemical composition and in vitro digestibility of the “capim-de-raiz” (Chloris orthonoton Doell). The treatments was obted in a factorial arrangement 3 x 2 x 2, with three rates of phosphorus fertilizer (0, 100 and 200 kg ha-1 of P2O5), two cut frequencies (30 and 40 days) and two […]

This work had the purpose to characterize the tillering and biomass accumulation dynamic, phenology and anatomic aspects. The experiment was conducted in Passo Fundo, Rio Grande do Sul, in which six plants were harvested every 15 days, between 21/10/99 to 21/04/00, in a completely randomized design. The times were accounted using units of growing degree-days (DD), calculated as the sum of the daily mean temperatures (threshold temperature = 0ºC). Transverse hand sections were used to observe the anatomic characteristics of […]
