Oat (<em>Avena ssp</em>) cultivars and lines evaluation

Abstract

The present study was carried out to evaluate the total dry matter production (TDMP), crude protein production (CPP), crude protein content (CPC), acid detergent fiber (ADF) in the following oat (Avena ssp.) cultivars and lines: SI 90173, IA 00887, SI 83002, IA 03687, IA 03187, IA 01587, SI 90056, SI 90092, SI 90045, SI 90095, Iapar 61 and black oat produced in both irrigated and non-irrigated soils. The experimental design was in randomized blocks with three replications. The average production of cultivars was 4,481 and 2,056kg of DM in irrigated and in non-irrigated area respectively. As for TDMP, SI 90056, SI 90173 and Iapar 61 presented the highest CPC (22.55%), while IA 03187 presented the lowest (18.67%). As for ADF, SI 90056 and Iapar 61 presented the lowest content, both in irrigated and non-irrigated areas. As for TDMP averages, the statistical analysis showed a significant difference (P < 0.05) between the cultivars only in the first cutting in irrigated areas. The cultivars SI 90056, IA 03687, SI 90045 and IA 00887 were the most productive yielding 2,776, 2,712, 2,678, and 2,668 DMkg/ha respectively. As for CPP, cultivars and lines differed significantly (P < 0.05) in both first and second cuttings only in the irrigated areas. The results also showed that CPC was higher in the first cutting, while TDMP and CPP were lower and ADF was higher in the second cutting for all cultivars.
