The tobacco plant is a biennial herbaceous plant that can reach 2 meters in height. Its stem is erect, sticky and unbranched under normal conditions. The leaves, which are the organ of use of the plant, are seated and large, although their morphology depends on the cultivar. They can reach 40cm long and 20cm wide. They give off a slight narcotic aroma due to their nicotine content.
The tobacco crop In Spain is very small, being about 8,500 hectares with an annual production of 26,000 tons of tobacco leaves
They prefer aerated soils with good drainage. If it is irrigated by fertigation and proper nutrition is ensured, lighter soils such as sandy or silty-sandy texture can be used.
Tobacco is a plant from the subtropical climate, although it can grow in temperate climates as long as its crop is avoided in the frosty season. It needs high temperatures to grow, of about 28ºC with night lows of 20ºC. Lower temperatures delay growth, and higher temperatures lower crop productivity.
Depending on the area, you will need 650 to 800mm per year of water to give a good production. It is very intolerant to salinity and chlorides, so it is recommended to use high-quality irrigation water.
In Spain the main variety that is planted is Virginia, accounting for two thirds of the total production. The Burleand variety would be second in importance.
