Abstract Sunflower is a crop that is used as ornamental, oleaginous,
forage, and currently as a bioremediation plant, of hard water
affected soils. For this reason, the main objective of this investigation
was to study the effect of potassium fertilization on yield under field
conditions, and the effect of gibberellic acid (GA3), at postharvest
of inflorescences. Two experiments were established, under field and
laboratory conditions. In the field experiment, four levels of potassium,
0, 50, 100 and 150 kg/ha were evaluated, under a randomized
complete block design and four replicates (4×4) = 16 experimental
units. The variables evaluated were agronomic and… More >
