Considered one of the most nutritionally rich legumes, soy has been noted in animal feed. Can be provided in the form of grains, soybea n meal, ground cob, silage, green mass, and also obtained as hay cutting phases of vegetative growth, flowering or fruiting. The objective was to evaluate the production of dry matter and protein in soybean varieties in different sampling times after full bloom looking toward a determination of the most favorable time for the production of silage, as the quantity and quality. An experiment was conducted in Selvíria - MS in agricultural 2009/2010 year, the Finance Teaching and Research, Faculty of Engineering - UNESP. We used a randomized complete block design in a 6 x 6 factorial design with four replications, comprising six soybean cultivars mid cycle and semi-late and six cutting periods (biweekly samples from R2 stage). Biometric owner were performed, and for each part of the plant in the assessments also determined the protein content. Depending on the results, it was concluded that all tested varieties yielded over 10 t ha-1 of total dry matter, peaking at 12,271 t ha -1 with cultivar AN 8500, the highest values of dry matter are obtained when cultivars are approaching the end of the cycle, percentage of dry matter in plants between 30 and 40% and the protein content follows a descending order as a function of grains, leaves, pods and stems.
