Despite the shortness of the field circuit, the tobacco plant is a plant that needs fertilization in terms of the amount of nutrients it removes from the soil. A fertilizer mixture is recommended according to the characteristics of each type of soil, even each field, because of the fear of excessive growth, coarsening of leaves, difficulty in drying and decrease in quality as a result of random use of organic or especially chemical fertilizers. Our quality tobaccos are grown under conditions that limit growth and development, by planting densely in medium-strength fields and with the effect of summer drought. Fertilizer should be given very carefully to the soils where high quality Turkish tobacco is grown.

In this respect, it would be appropriate to divide our tobaccos into two categories in terms of fertilizer needs.

1- Tobaccos with large or medium leaves planted at wide distances, high nicotine and strong (normal) growing and developing (Puro, Tömbeki, Virginia, Burley, Hasankeyf, Trabzon, etc.) prefer strong soils, there is no harm in fertilizing them abundantly.

2- Quality tobacco with medium or small leaves planted at narrow distances, growing under low nicotine conditions and restricting growth and development (Samsun, Basmas- Izmir, G.Hacikoy -Bafra, Marmara Region tobaccos, etc.) they need a fertilization. As a result of excessive fertilization / irrigation, newly planted tobacco plants grow rapidly and their leaves grow larger. Tobacco cannot reach its crushing maturity. Since the tobacco plants that cannot find enough water will start to wilt and wilt due to the pressure of the heat, it may be necessary to irrigate the tobacco fields where excessive fertilizer is given. The chemical and physical values of irrigated tobacco diverge from the quality standards required by the market, which are sought in cigarette blends.
