Influência do esterco bovino na produção e qualidade proteica da cultivar de azevém brs ponteio

Abstract

The ryegrass is a winter forage specie commonly used in the south of the country in reason of its adaptability to the region climate conditions and for having the natural regeneration capacity. Therefore, the goal in the present study was to evaluate the BRS Ponteio variety ryegrass production and its protein quality under different levels of cattle manure. The experiment was carried out at the UERGS Rural Campus, located in Santana do Livramento/RS. The experimental design was the randomized blocks with three repetitions by block. The experimental unities were 4 m² land portions. The treatments were five bovine manure levels of 0, 37, 74, 111 and 148 T ha-1. Were evaluated the following characteristics: the shoot natural and dry matter, crude protein content (at 1st, 2nd, and 3rd cuts) and the leaf/stem ratio. The results showed that the use of cattle manure promoted a linear response on the natural and dry matter production in all the cuts analyzed. Also, the treatments with higher bovine manure levels showed higher crude protein content and a higher leaf/stem ratio. The highest production of natural matter, dry matter, crude protein and highest leaf/stem ratio happened in the second cut.

Dose de máxima eficiência técnica de composto orgânico para aveia preta (Avena strigosa)

“…Já para a matéria seca, a produção máxima acumulada (3.0 Mg ha -1 ), foi a partir da estimativa da DMET de 22,7 Mg ha -1 . Schüller, et al (2020) verificaram uma produção de matéria seca acumulada do Lolium multiflorum L. cv. BRS Ponteio, inferior aos 3000 kg ha -1 na dose máxima estudada (148 T ha -1 ).…”
