The strawberry is a culture of high economic impact to producers in Brazil, with great emphasis on the state of Minas Gerais, where the largest area of cultivation is concentrated in the South, which has areas with altitudes ranging from approximately 800m and 1400m altitude, with different air temperatures. The planting in the region runs from March to May. Thus the aim of this work the evaluation of yield of strawberry plants in different growing seasons in southern state of Minas Gerais. The experiment was conducted in the City of Good Home, using four cultivars (Aroma, Camarosa, Festival and Oso Grande) and four planting dates (May, June, July and August) of 2007. The experimental design was a randomized block design (RBD) with five replications in a split plot, constituting the main plots planting dates and cultivars the sub-plots. The harvest began in August and ended in February, where he established a harvest time of 4 months for each planting season. We evaluated the following characteristics: number of total fruits, numbers of commercial fruits, numbers of non-marketable fruits, fruit weight Overall, mass of marketable fruits and fruit mass non-commercial. In the chemical analysis of fruits were evaluated: total soluble solids, titratable acidity, firmness and soluble solids / total acidity. For number of total fruits, numbers of commercial fruits occurred significant effects planting season (EP), cultivars (C) and (EP) x (C). For numbers of unmarketable fruits significant effects occurred only for planting dates and cultivars. For the mass of total fruits, weight of marketable fruits and weight of unmarketable fruits occurred significant effects for factors planting dates, cultivars and planting date (Ep) x Cultivar (C). Total soluble solids, there were no significant differences for Total Titratable Acidity effects were significant only for growing, for firmness were no significant effects. For soluble solids / total acidity effects were significant only for cultivars.
