A field experiment was carried out on a Red Yellow Podzolic soil, in order to determine the sunflower response to liming, boron and their interactions. A randomized complete block design (Split-plot) was used with four replications. In the main plots, limestone was broadcasted at rates of 0, 2, 4, 6, and 8 t/ha and in the sub-plots boron was applied banded at planting time, at rates of 0,1 and 2 kg/ha as boric acid. The results showed that sunflower is very susceptible to soil acidity, manganese toxicity and boron deficiency. Liming increased plant height, head diameter, phosphorus uptake and grain yield, mainly when it was associated with boron fertilization. There was no effect of treatments on seed oil content. The grain yield was also correlated with soil testing and leaf analysis. It was concluded that the aluminum criterion was inadequated for determining lime reuirement for sunflower. Otherwise, better agreement was obtained with the method based on the correlation between pH and soil base saturation. |
