Meadow and field forage production

Ivanova E. P., Emelyanov A. N. Eff ect of sowing methods on the productivity of alfalfa for a long-term use in Primorye

5

УДК: 633.31: 631.53.04 :

Alfalfa growth is the most inhibited under cover of annual ryegrass, the effect persists in the second year of life of alfalfa. Spring barley affects alfalfa less. Coverless sowing of alfalfa is more productive, but it is possible only on the weedless fields. Since the second year of life alfalfa is capable of forming highly productive stands giving up to 40–50 t/ha and more green mass of high nutritional value.

Keywords: variable alfalfa, cover crops, crop yield, green mass, dry mass, years of life.
