Abstract

The aim of the present study was to investigate the influence of sowing rate (120, 150, 187.5, or 225 kg·ha^–1) and row spacing (20, 25, 30, or 35 cm) on the height, branch number, ear length, grains per spike, grain weight per spike, 1 000-grain weight, and seed yield of forage rye using a two-factor randomized block experiment. The aim was to establish a theoretical basis for producing forage rye seed in the high-altitude colder regions of China. Sowing rate had a significant effect on plant height, ear length, grain weight per spike, 1 000-grain weight, and seed yield (P < 0.05) but failed to significantly affect branch number or grains per spike. Meanwhile, row spacing had a significant effect on seed yield and branch number (P < 0.05) but failed to significantly affect plant height, ear length, grains per spike, grain weight per spike, or 1 000-grain weight. Therefore, either sowing rate or row spacing, or both, significantly affected every measured variable, except grains per spike. Below 2 800 m in elevation in Gansu Province, the greatest seed yield (≤ 6 590 kg·ha^–1) was achieved using a sowing rate and row spacing of 187.5 kg·ha^–1 and 30～35 cm, respectively.
