The oldest native oilseed crop in India with the longest history of cultivation is sesame (Sesamum indicum L.). Across India, many languages have different names for sesame, or gingelli: til (Hindi, Punjabi, Assamese, Bengali, Marathi), tal (Gujarati), nuvvulu, manchi nuvvulu (Telugu), ellu (Tamil, Malayalam, Kannada), tila/pitratarpana (Sanskrit), and rasi (Odia). Sesame seeds are used in baking, candies, and other culinary industries. They include 50% oil, 25% protein, and 15% carbohydrates. It is essential to religion, society, and rituals. The oil, which has a 40% oleic and 40% linoleic acid content, is used in cooking, salad dressings, and margarine. Because sesame oil contains sesamol, an antioxidant, dishes fried in sesame oil have a long shelf life. The oil can be used to make paints, pesticides, soaps, fragrances, and medications. For animals and poultry, sesame meal is a great high-quality feed that contains 40% protein. In addition to being a storehouse of energy, sesame seeds are also a great source of calcium, phosphorus, iron, copper, magnesium, zinc, and potassium, as well as vitamins E, A, and B complex. It is the greatest alternative to breast milk, particularly for those who are allergic to it. Abundant amounts of methionine, tryptophan, and other amino acids with several health benefits can be found in sesame seeds. When it comes to assigning technology, front line demonstration is one of the most effective techniques available. The goal of the current study was to determine the yield gap on sesame crops using OFTs. In 2021, Krishi Vigyan Kendra conducted forty sesame demonstrations in a few chosen villages within the Mahasamund district, during both the summer and the kharif season. The recommended practices were compared with the practices of the majority of farmers. In comparison to farmers' practices, which yielded 3.8 and 3.6 q/ha, respectively, the yield of the shown plot was 8.9 q/ha to 7.86 q/ha in both seasons. The technology index varied between 28.33 and 9.34 percent in both seasons, while the technology gap to extension gap ranged from 3.51 q/ha to 5.1 q/ha in kharif and 0.81 q/ha to 4.26 q/ha in the summer.
