Abstract

The experiment was conducted in the 2013/14 season, in an experimental area of the C-Valle, in Palotina Municipal District, Parana State, Brazil. The cultivar used was Monsoy 6210 IPRO. The experimental design was a randomized block with four replications. The treatments consisted of basic fertilization (AB) in soybean sowing, AB + 20% AB + 40% AB + coverage with potassium, AB + 20% + coverage with potassium and AB + 40% + coverage with potassium. The variables evaluated for agronomic performance of soybeans were: Plant height, first pod height, number of pods per plant, yield and mass of one hundred seeds. Could not find significant differences in the variables analyzed. We conclude that the fertilization treatments were not effective for the increase of soybean grown in clay soil parameters. The crambe culture can be considered a culture that recycles nutrients and has good potential for the use of residual fertilizer from previous crops.

Key words: Residual fertilizer, base fertilizer, nutritional requirements.
