Abstract: Further intensification of the fodder production industry is closely related to the rational use of land, irrigated water, labor resources and new approaches to increase the yield of fodder per unit area. One of the ways to effectively use resources such as land, irrigation water, as well as mineral fertilizers and labor resources can be considered to be an increase in the area under joint crops of several types of agricultural plants. To improve the efficiency of agricultural production, especially in fodder production and the rational use of irrigated lands, irrigation water, mineral fertilizers and labor resources, we have developed new innovative methods for introducing in production methods of combined sowing of several fodder crops in the same field. As such crops, we used such plants as Jerusalem artichoke, corn, sorghum and sunflower. Combined sowing of Jerusalem artichoke with other forage crops contributes to an increase in the total mass of dry matter per hectare by 29–41%. Important factors contributing to an increase in the yield of green mass with combined crops are: plant density, an increase in aboveground mass due to the re-growth of Jerusalem artichoke and sorghum stems by the end of the growing season (by the end of November). The best option in the experiment was the combined sowing of four fodder crops: Jerusalem artichoke + sorghum + sunflower + corn. In this version of the experiment, compared with the control version, the yield of green mass was higher by 172.7%; total biomass — by 53.2%; profitability — by 23%. Due to the increase in yield, the profitability of combined forage crops is 8–23% higher compared to the control option — pure Jerusalem artichoke sowing.
