Abstract	COMPAGNONI, Luciano. Soil unpacking and additional fertilization in soybean productivity. 2013. 35f. Dissertação (Mestrado em Ciência e Tecnologia de Sementes) Programa de Pós-Graduação em Ciência e Tecnologia de Sementes, Universidade Federal de Pelotas, Pelotas, RS. The soybean has enormous importance for the country. Increasing the productivity of this crop represents social and economic gains while preserving natural resources. Crops demonstrative show that current soybean yield is well below its potential, it is necessary to investigate what are the factors that limit current productivity. The aim of this study was to measure the response of factors, additional fertilization and decompression on soybean yield. The experiment was conducted in a commercial farm in the municipality of Lagoão, RS. The experimental design was a split plot. The plots were arranged treatments with two levels of compression; Packed and unpacked and subplots were arranged five additional fertilizer levels (zero, 250, 500, 750 and 1000) the formula 5-30-10. Assessments of productivity, yield components and seed quality were performed at the Laboratory Textbook of Seed Analysis, Federal University of Pelotas (LDAS / UFPel). Statistical analysis was performed using analysis of variance and hypothesis testing to verify the significance of main effects and interactions. For mean comparison test was used to tukey 5% and / or 1% probability. There was no interaction between the two factors. The additional fertilization has not improved productivity and not interfered in physiological seed quality. Decompressing yielded average productivity of 14,2 more sacks, produced taller plants with greater stem diameter, pods and more seeds per meter, the greater weight of dry matter per hectare and had lower harvest index.
