Abstract
The effect of plant density on yield of small (13 to 18 mm diameter, 7.5 to 11.5 cm long) finger carrots was studied in two experiments, one using cv. Manchester Table, the other using cvs. Little Finger, Tiny Tot, Indcx, and Manchester Table. With sowings at densities wnging from 533 to 2500 seeds per square metre, yield increased with increasing density. The highest yiclds were obtained at the highest density used, and ranged frorn 51.5 tonnes/ha for cv. Manchester Table to 90.6 tannes/ha for cv. Index. At each density yields of finger carrots classed as small reached a maximum for about 1 week. This maximum yield was reached earlier at low than at high densities. When plants were spaced close to equidistant bdween and within rows, a yield lower than might have been expected in relation to density was obtained in all cultivars except Little Finger.
