Extract

The writer has pointed out the influence that some agricultural plants have on others when grown in close proximity to them. It was demonstrated (inter alia) that a row of Sesamum indicum (gingelly), when sown at a distance of two feet from a row of Sorghum vulgare (great millet), will not mature, the plants dying after reaching a height of a few centimetres. These experiments were made at Surat (India) on black cotton soil of a very retentive nature; this character of the soil combined with a rainfall of 42 inches per annum all falling in 3½ months, doubtless emphasized the deleterious effect of the sorghum on the sesamum since the washing of the soil was a minimum.
