Description
A seed-shattering-resistant cultivar and a normal cultivar of meadow rescue (Festuca pratensis Huds.) were harvested for seed 10 times in regular intervals during a period of 30 days, The effects of harvesting time on yield, water content, germination and weight of seeds, and on costs of seed processing were studied in the 2 types of cultivar. Yield losses due to premature harvest were greater than losses due to delayed harvest. Seed losses due to shattering were smaller in the shattering-resistant cultivar compared with the normal cultivar. The water content of the seeds decreased with advancing maturity, from =50% to .. 10%. The maximum yield was obtained at =40%H20. Germination percentage and 1000-seed weight were not significantly affected by harvest date. The costs of seed drying exceeded those for seed cleaning on early harvest dates but were substantially reduced in the period after maximum seed yield. In this period the reduction of drying costs never surpassed the reduction of seed value due to delayed harvest.
