GROWTH OF SUN FLOWER ON THE MEDIA OF SIDOARJO’S MUD SOIL WITH ORGANIC MATERIALS

Sunflower (Helianthus annuus L) is a plant-producer of important edible oil and occupies the world’s third-highest position after soybean oil and palm oil. This plant can grow in Indonesia which has various climate and soil types. Sidoarjo’s mud soil is an alternative choice as a growth media with organic materials. This research’s objective is to determine the best sun flower growth on media of Sidoarjo’s mud soil in which mixed by organic materials. The sample of Sidoarjo’s mud soil was mixed with rice husks, compost and cow manure with different doses into 10 types of growth media. The growth media were incubated for 5 weeks and then planted by sun flower seeds. The media M1 produced the best growth of sun flower compared to other media. This research concluded the best sun flower growth was in media M1 which was a mixture of Sidoarjo’s mud soil of 20%, rice husks of 40%, compost of 20% and cow manure of 20%.
