Effect of sowing date and plant population on seed and herbage yield in common vetch (Vicia sativa)

摘要

In a field experiment in 1993-95 in Jordan, V. sativa was sown during mid-November, mid-December or mid-January at densities of 80-280 viable seeds/m2. Delaying sowing decreased seed yield. Seed yield was highest with up to 160 seeds/m2. Herbage drymatter yield was highest with 280 seeds/m2.
