N2  - In experiments at Katherine, N.T., yields of the Spanish peanut, variety Spantex, were not increased by sowing in twin rows spaced G inches apart with 3 feet between the pairs of rows, in comparison with normal single rows sown 3 feet apart. Establishment was, however, improved by up to 12 per cent by sowing in twin rows, presumably owing to reduced competition for soil moisture with the lower plant population per unit length of row. Yields were little affected by plant population in the range 40,000-120,000 plants an acre, corresponding to sowing rates of 50 to 200 lb an acre of kernels. In one season a significant increase of 240 lb an acre (9 per cent) of nuts-in-shell was obtained by increasing the sowing rate from 50 to 100 lb an acre. In two other seasons, however, yields were not affected by the change in plant population. Planting on formed beds led to a reduction of G per cent in establishment compared with flat planting; but yields were not affected. The optimum seeding rate for Spantex at Katherine, N.T., is considered to be approximately 50 lb an acre, giving a plant stand of approximately 40,000 plants an acre.
