ABSTRACT

In a field experiment conducted in 2005–2007 on light soil, medium-tall
leafy field pea (Pisum sativum L.) cultivar Wiato (dry seed type) and
tall leafy pea cultivar Fidelia (green forage/dry seed type) were grown in two-species
mixtures with spring barley (Hordeum vulgare L.). The aim of the research
was to assess the effect of partial separation of the components in the intercrop
on barley-pea interaction, canopy lodging, biomass yield and grain production.
The species were sown in intercrops using separate passes of the seeder in the
same direction, with pea seeded first in regular row spacing of 10.8 cm. The
partial species separation was achieved through sowing barley in four different
row arrangements in the intercrop: uniform row spacing of 10.8 and 21.6 cm, and
alternate row spacing of 10.8/32.4 cm and 10.8/43.2 cm. The intercrop with barley
seeded in rows spaced 10.8 cm apart and that with alternate row spacing of 10.8/43.2
cm yielded the same grain during the experimental years. Compared to those, the
mixture with alternate 10.8/32.4 cm row spacing of barley yielded significantly
less grain in 2005 and 2006.

Key words: plant lodging, competition, facilitation, resource complementarity, row spacing.
