An alternative to include these areas in the productionprocess, it is their conversion to animal production in this period, with the cultivation of winter forage for grazing or forageconservation. Under this approach, oats are configured in one of the most viable alternatives. The objective of this study was toevaluate the total and monthly yield of black (Avena strigosa Schreb.) and white (Avena sativa L.) oat cultivars in South andSoutheast of Brazil, in order to identify the materials with the greatest potential and better production profile for each location. Theexperimental design was a randomized block with four replications. Cultivars IAPAR 61 (black), IPR 126 and FAPA2 (white) wereevaluated under cutting in the autumn/winter periodsbetween 2004 and 2007 in São Carlos (São Paulo), Ituporanga and Lages(Santa Catarina), Southeast and South of Brazil respectively. Over the four years of evaluation, cultivars showed similarproductivity in each locality. Productivity between locations varied, with São Carlos producing on average 6.6 Mg DM ha-1,Ituporanga 4.3 Mg DM ha-1 and Lages 2.9 Mg DM ha-1 in the five months of cultivation. The difference in productivity betweenSão Carlos and Ituporanga is probably due to higher average temperatures at this time of year in the Southeast, since the soilfertility in the two locations is similar. The lowest yield of Lages over Ituporanga, places with similar climate, probably due to thelower fertility of soils characteristic of Lages. Seasonal yield was different among black and white oat cultivars. Black oats yielded25% of the total in May, whereas white oat yielded 29%. During June black oats yielded 27% and white oats kept 29%. July wasthe month when white oats started to decrease their production yielding an average of 25%, the same proportion of the black oat.In August the production decline for all the oats with white oats producing an average of 17% and black oat 23%. Any of theevaluated cultivars can be recommended for forage use, since all showed similar yield and seasonal distribution at each location..See more from this Division: C06 Forage and GrazinglandsSee more from this Session: General Forage and Grazinglands: II<< Previous Abstract | Next Abstract >>
