It was aimed to verify the chief leaf diseases that occurs in alfalfa, in Lavras-MG, state of Minas Gerais, of 1997 september to 1998 october. A randomized block trial subplots in time, whose factors were 35 alfalfa cultivars in the plots and 11 evaluation times, which corresponded to the months, in subplots. Evaluations were performed at 28 days after the cut, when ten stems here collected by plots for evaluation of defoliation and determination of severity of the diseases. The […]

Information about cultivars behavior obtained from only one local and year may not be enough for a cultivar recommendation due to the genotype x environment interaction occurrence. Then, cultivars indication based on stability and repeatability is more consistent because it enables previewing theirs performance under many environments. This work studied the adaptability and repeatability of dry matter production of seven sorghum cultivars to be used as silage. Data came from two sites (Coronel Pacheco and Lavras, Minas Gerais) and were […]

The effect of different cactus forage cultivars upon the productive performance of 5/8 Holstein/Zebu dairy cows was studied. A latin square design was used in an alternative assay distribution, with three squares and three periods of 28 day each. The treatments were constituted of the cactus cultivars “Redonda”, “Gigante” and “Miúda”. A few variations in the chemical composition were observed among cactus cultivars. No differences were observed as for fresh cactus forage and corn stalks intake, and dry matter intake, […]
