Resumen


The aim of this study was to evaluate hay yield and quality of local oat
genotypes at different locations. Twenty-five oat genotypes were evaluated in a
randomized block design with four replicates at three locations during the two
growing years. The hay yield, crude protein (CP), acid detergent fibre (ADF),
neutral detergent fibre (NDF), relative feed value (RFV) and macro minerals (Ca,
K, P and Mg) differed significantly with genotype (G), location (L), and year (Y).
The G × L interaction was significant (P<0.05) for hay yield, crude protein and
Mg ratio. According to the combined results of location and years, among the
genotypes, yield varied from 8.48 to 10.78 t·ha-1, crude protein from 93.7 to 119.4 g·kg-1, acid detergent fibre (ADF) from 336.3 to 371.9 g·kg-1 and neutral detergent fibre (NDF) from 553.0 to 588.7 g·kg-1. The relative feed value (RFV) ranged from 95.5 to 106.6. G10 (10.78 t·ha-1), G8 (10.42 t·ha-1), G24 (10.40 t·ha-1), G5 (10.33 t·ha-1), G15 (10.25 t·ha-1), G12 (10.10 t·ha-1), G6 (10.08 t·ha-1), G13 (10.03 t·ha-1), G4 and G18 (9.80 t·ha-1) and G14 (9.76 t·ha-1) numbered genotypes were specified as the high yield potential genotypes. Besides, among these genotypes, G10, G5, G15, G13, G4, G18 and G14 genotypes also showed superior performance in terms of quality characteristics. Furthermore, the results obtained for K, P, Ca and Mg concentrations in this study were adequate for ruminants.
