Behaviour of sunflower in relation to soil acidity






Bragantia 44(1): 41-48

Behaviour of sunflower in relation to soil acidity

In a rotation trial in 1981-82 at Mococa some plots of sunflower Anhandy showed poor germination, reduced growth, leaf chlorosis, curved main roots and fewer amd thicker secondary roots. Seed yield, plant height and capitulum diam. were correlated positively and linearly with soil pH and base saturation.
