Resumo: | The study was carried out from March 1997 to April 1998 aiming to evaluate the effect of water levels irrigation in the yield, in the distribution and chemical composition of alfalfa in field tests. The experimental design was totally randomized with four treatments: non-irrigated (T0), irrigated at 50%, 75% and 100% of the field capacity, considering 5 replications. In respect of the dry matter production, there was a significant difference (p < 0.05) between the water levels, irrigated and non-irrigated, and 100% of the field capacity. And there was also the effect of the year season (p < 0.05) with the summer yield being higher than the winter yield. The cuttings in different seasons of the year did not affect (p < 0.05) the crude protein (CP), the neutral detergent fiber (NDF) and the acid detergent fiber (ADF). Nevertheless, the irrigated alfalfa showed higher CP content (p < 0.05) and lesser NDF and ADF, throughout the year. The maximum forage yield and quality of alfalfa cv. Crioula was only possible using the irrigation in field capacity with irregular distribution during the year, in spite of the fact that irrigation elevates the forage production and improves the chemical composition in both seasons. |

Crioula) em ensaio de campo. O delineamento experimental foi inteiramente casualizado, com 4 tratamentos: ausência de irrigação (T 0), irrigado a 50 (T 50), 75 (T 75) e 100 (T 100), como porcentagem da capacidade de campo, com 5 repetições. Para produção da matéria seca houve diferença significativa (p < 0,05) entre os tratamentos irrigado e não irrigado, e efeito de estação do ano (p < 0,05), sendo o verão superior ao inverno. Os cortes nas estações do ano não diferiram quanto aos teores de PB, FDN e FDA nos tratamentos. Entretanto, a alfafa irrigada apresentou maior teor de PB (p < 0,05) e menor teor de FDN em relação à não irrigada, independentemente da época do ano. A exploração do potencial máximo de produção e qualidade de alfafa cv. Crioula só foi possível mediante a irrigação na capacidade de campo do solo com distribuição irregular da forragem durante o ano, apesar da irrigação elevar a produção e melhorar a composição química da forragem nas duas estações do ano.Universidade Estadual de Maringá2008-04-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/267410.4025/actasciagron.v25i1.2674Acta Scientiarum.
