Udalets brome grass is a highly effective forage crop capable of providing significant yields of both green mass and seeds. Experimental research conducted at the experimental field of the Penza State Regional Research Institute of Agriculture and Veterinary Science showed that the optimal sowing time is the first and second decade of May. At this planting time, the maximum green mass yield is achieved in the range of 35.5–37.2 t/ha, along with a significant increase in seed yield up to 614 kg/ha.
An important aspect of growing 'Udalets' is its competitiveness in mixed sowings with variable alfalfa. At a sowing rate of 70% for alfalfa, brome grass maintains high competitiveness, but at a reduction to 40%, competition shifts in favor of brome grass. The application of mineral fertilizers (N45P60K90) enhances the growth and development of brome grass, increasing its share in the mixture.
The economic efficiency of cultivating 'Udalets' is confirmed by cost calculations: at a sowing rate of 70% for alfalfa and 40% for brome grass, using a complex fertilizer N45P60K90 and harvesting at an early stage, the cost of producing one ton of forage unit is approximately 2.36 thousand rubles. These figures make the 'Udalets' variety an attractive choice for farmers seeking high yield and economic benefit when growing brome grass.
