Abstract	Strassburger, André Samuel. Growth, dry mass partitioning and fruit yield of strawberry in organic crop system. 2010. 124 f. Thesis (Doctor in Science). PostGraduation Program in Sistema de Produção Agrícola Familiar, Universidade Federal de Pelotas, Pelotas. Adviser: Dra. Roberta Marins Nogueira Peil. The strawberry cultivar choice is an important factor for the success of the crop. The time crop, yield and quality of the fruits and resistance of diseases are important aspects to consider. In strawberry growing in organic crop system should consider too, that the modern cultivars currently available for the farmers were developed in breeding programs characterized by the use of conventional crop system. Therefore, the cultivars developed from these programs can obtain smaller growth, yield and fruit production in organic crop system. Therefore, the aim of this work was to study the growth, dry mass partitioning and yield of strawberry cultivars in organic crop system. Thus, two trials were conducted. The objective of Trial 1 was to evaluate the border effect on growth of Albion, Aromas, Camarosa and Camino Real strawberry cultivars as well as the dynamics of these cultivars along the crop-season. The objective of Trial 2 was to evaluate the plant density effect (determined by row number per bed – 2; 3 and 4, providing densities of 3.51; 5.26 and 7.02 plants m, respectively) on the growth of Aromas and Diamante strawberry cultivars. The trials were conducted in Embrapa Clima Temperado/Estação Experimental Cascata, Pelotas, RS. The plant setting was performed in 05/12/2008 (Trial 1) and 07/04/2008 (Trial 2). The randomized blocks experimental design was used with four replications. From the data of aboveground biomass production and leaf area, the dry mass production and partitioning among the different aboveground organs, as well as yield and others interesting index and rates of growth were determinate. The obtained results from Trial 1 indicated that there are no border effects for the Albion, Aromas,
