Abstract
Corms of Sparaxis tricolor were planted in the second 10 days period: from 20th April to 20th May, on three depths: 4 cm, 6 cm and 8 cm. The largest number of descendant corms and fresh matter of total and commercial yield was obtained from corms planted in the field on 20th April. Retarding of planting date influenced dispersion of the total yield of offspring corms. The largest number of corms produced in corners of leaves was obtained in the second 10 days’ period of April. Depth of planting did not influence the total yield of corms. Plants from earlier terms produced, more descendant corms at the depth of 4 cm, while these from May dates more descendant corms produced at growing depth 8 cm.
