abstract:
The seeds of alfalfa cv. Legend as well as hybrid alfalfa cv. Radius were irradiated with divergent He-Ne laser bundle directly prior to sowing. The field experiments were carried out in the years 2003-2004 by using the method of the land random square (20 m2) and four repetitions. Lucerne variety and six doses and repetitions of irradiation were taken as independent variables. The following parameters were estimated from field experiments: number of shoots of Lucerne, dry matter of single shoot, cropping yields of green and dry matter, percentage of cut in one-year crop yield and percentage of leaves in dry matter. Laser stimulation resulted in growth of the number of shoots per 1 m2 and the yields of green and dry matter.
