    Abstract
    In trials in the 1973 short rains and the 1974 long rains at Kabete, Kenya, soyabean cv. Hill was sown at plant populations of 111 111, 250 000 or 1 000 000/ha on the square (10 X 10 cm, 20 X 20 cm or 30 X 30 cm) or in rows 50 cm apart and at within-row spacings or 2, 8 or 18 cm. Plots were either (a) kept weed-free for the 1st 4 wk, (b) after 4 wk, (c) at all times or (d) were not weeded. The short-rains trial failed due to shortage of rain; seed yields were 0-199 kg/ha. In 1974, yields ranged from 1.71 t/ha at 20 X 20 cm to 2.22 at 10 X 10 cm, and from 1.1 t in (d) to 2.50 and 2.52 t in (c) and (a), resp. There was no evidence that high plant populations helped to control weeds or that plant arrangement affected yields.
