Production and chemical composition in oat cultivars and lineages (<em>Avena spp</em>)

Abstract

The objective of this work has been the evaluation of total dry matter production (TDMP), crude protein content (CP), crude protein production (CPP), neutral detergent fiber (NDF) and leaf and stem percentages of different oat cultivar and lineages Avena spp (Poaceae): FAPA, ER 93210/2, ER 93247/2, UPF 77S436, ALFA 94155, ALFA 94206, UPF 77S456, ER 90418212, ER 9314-1, IA 96101-3, UPF 93AL209-1, UPF 92298, SI83400, UTFP 9704, UTFP 9706, IAPAR 61, EMBRAPA 29, UPF 93AL203/3. In the first cut, cultivar UTFP 9706 was outstanding in the production of TDMP and CPP. Yield produced 408 kg CP/ha. In the second cut, there was no difference between cultivars and lineages. In the second cut, the CP content was highest in IA 96101-3, UPF 93AL209-1 and IAPAR 61, while NDF was highest in UTFP 9704 e UTFP 9706. Leaf blade percentages was higher in the first cutting; ER90418212 was outstanding, with 88% leaf blade. In the second cut, the ER93247/2 yielded 71% leaf blade, but with low total dry matter.
