Manuring
Sunflower is an exhaustive crop and responds well to fertilizers. However, high doses of
nitrogen lead to luxuriant vegetative growth and reduction in oil content. In general, 40 kg nitrogen
and 60 kg P2O5 per hectare may be drilled before sowing. If the crop shows poor growth, another
dose of 20 kg nitrogen per hectare may be top-dressed one month after germination.
