Abstract:
Sunflowers are one of the flowers chosen by many localities to grow because they both create beautiful landscapes and are also a source of raw materials for oil from the seeds. This study aims to determine the planting density and amount of fertilizers being suitable for growing, well-developed, high-yielding in Thua Thien Hue province. Research results shown that planting density and fertilization did not significantly affect the germination rate and growth time of sunflower in the winter crop season. The density did not affect the number of green leaves on the plant, the diameter of the calyx, the diameter of the flower, and the durability of flowers. At the fertilization level of 90 kg N + 60 kg P2O5 + 90 kg K2O per one hectare had the highest numbers of green leaves per plant and the diameter of calyx, flower diameter, and flower durability were highest. Planting density and fertilization had an interaction affect on the plant growth and yield. The largest stem diameter was at the planting density of 50.000 plants/ha and fertilization of 60 kg N + 90 kg P2O5 + 80 kg K2O per hectare. The treatment with the planting density of 62.500 plants/ha and fertilization of 90 kg N + 60 kg P2O5 + 90kg K2O per hectare had the highest plant height, leaf area and actual yield.
