Pot experiments with Chenopodium album were carried out in phytotrons and outside in a roofed coolhouse in 1969—70. Number of branches per plant was higher in a sparse than in a dense stand at phytotoron temperature of 12° C. Leaf area index (LAI) was smaller, leaf area per plant larger in a sparse than in a dense stand. Root and leaf yield as well as total plant weight were larger in a sparse than in a dense stand. Total C. album yield per unit area was higher from a dense than from a sparse stand. Growth density and temperature had a notable effect on the shape of the yield curve (Figs. 4—5). Daily yield increase per plant was larger but the increase per unit area smaller in a sparse than in a dense stand. Length of the period vegetative ...
