Abstract

A detailed study of the components of a crop of linseed that determine the seed yield was made in 1991. Sub-samples of thirty plants from five distinct poulations were taken and analysed. Number of tillers/plant, number of capsules/plant, and number of seeds/capsule were recorded. The thousand seed weight and the weight of individual plants components was measured and a harvest index and theoretical yield calculated and compared wth the combine harvested yield of that population. Crops with low plant populations compensated for fewer plants by increasing tillering and capsule number. The harvest index for linseeed was caluclated at 38%. Yields from populations of 233-713 plants/m2 were simuilar due to compensation.
