Kalaus is a grain sorghum variety developed by the Stavropol Scientific Research Institute of Agriculture and introduced in 2005. It belongs to the mid-late maturity group and is intended for cultivation in specific regions where it demonstrates good agronomic characteristics. Kalaus sorghum is used as an agro-product and is distinguished by its resistance to various growing conditions.
Research conducted under the forest-steppe conditions of the Republic of North Ossetia-Alania showed that the vegetation period of Kalaus varies depending on the sowing time and application of mineral fertilizers. In the absence of fertilizers, the vegetation period ranges from 135 to 145 days; with the application of NPK fertilizer at a dose of 45 kg of active substance per hectare, it shortens to 130-138 days, and with a dose of 90 kg, it slightly increases but remains shorter than without fertilizers. The optimal sowing period is recognized as the time when the soil is well-warmed, which promotes faster plant development.
Kalaus is characterized by good adaptability to various soil and climatic conditions and can be successfully cultivated in forest-steppe and steppe zones. Thanks to its characteristics, such as resistance to adverse factors and the possibility of regulating the vegetation period using agronomic techniques, this variety is a promising choice for grain production.
