Sunflower (Helianthus annuus) is an annual herb with a rough, hairy stein, 1-4.5 meters high, thick and coarse, rough leaves, arranged in spirals, about 7.5-30 cm long. The attractive flowers in wild specimens are about 7.5-15 cm across and in cultivated plants sometimes about 30 cm or more. It is grown to consume oil from the seed. This species of suntan is used in some industry applications as wild bird feed, as animal feed (as a meal or as a silage plant), and as an ornamental garden. The plant was first domesticated in the USA. The sunflower name is derived from the shape of the sun-like moral head. During the 16th century the American sunflower seeds were brought into Europe, which along with the sunflower oil became a popular cooking ingredient in the world, after 3000 B.C., many sunflower applications, including ornamental plants, drugs, food, fodder, textile teeth, body paints, decorations, etc. have been produced. The species of sunflower are allelopathic in nature and this plant looks forward to a bright future. But farmers have to manage soil fertility levels to cultivate sunflower with an integrated approach which blends organic and inorganic methods in order to grow sunflower crops successfully. Fixing inorganic approaches to nutrient imbalances does not only contribute to sustainable high crop yields, but also eliminates the need for wasteful marginal lands. Fertilizers are organic or inorganic chemicals which help plants grow and increase soil fertility. Organic (manure) fertilizers have a low percentage of nutrient material. Inorganic or mineral fertilizer nutrients constitute inorganic salts, which arc extracted through physical or chemical processes. N, P, K are the three most important plant nutrients. Inorganic fertilizer components such as N, P, and K are essential nutrients for plant development and productivity. A well-balanced fertilization of each was crucial in providing the nutrients needed for maximum sunflower growth. Nitrogen and potassium levels influenced plant height, biological yield, seed yield, and seed oil content. Application of nitrogen and phosphorus also aided growth and output. The amount of NPK fertilizer employed influenced plant growth, sunflower grain production and maximum grain yield
