Prospects for Sorghum cultivation in Poland

Abstract

The article presents the origin and cultivation history of sorghum (Sorghum spp.), its biology, requirements, cultivation techniques, and utilization. Sorghum is a cereal of the Poaceae. It is one of the most important crop plants grown in warmer parts of the world. Sorghum comes from Africa and therefore has very high heat requirements. In comparison with other crop plants, it is characterized by more efficient nutrient and water utilization. Sorghum grain is used to produce porridge, flour, syrup, sugar, ethanol, vegetable oil, starch, wax, paints, and animal fodder (the grain and entire plant). Sorghum straw is used to produce fibres, paper, and building materials. Sorghum has high energy value and can be an excellent source of renewable energy. It is easy to cultivate, with low soil and nutrient requirements. Due to its content of allelopathic compounds, it inhibits weed growth and has a phytosanitary effect. It is also resistant to disease and pests. It is a short-day plant, and in Polish climate conditions, it does not form sufficiently mature seeds, but produces a very high yield of green matter that can be used for fodder. Cultivation of sorghum during periodic water shortages may be an alternative solution for obtaining fodder when maize cultivation is unreliable.
