Summary: | Parameters of plant productive organs (spike, pod etc.) are influenced by
genotype of plant species and scientific technology farming measures as well
environmental conditions. The aim of this study was to establish variability
of spike harvest index for wheat, triticale, rye, oat and pea pods index,
influenced by monocrops and intercrops system of cultivation. Four cereal
species: wheat, triticale, rye and oat and one legume (pea) were included in
investigation that carried out on field experimental conditions during one
vegetation season. Each species were sown in monocrops and in intercrops
wheat + pea, triticale + pea, rye + pea and oat + pea. Harvest index of
spike variate between 65.2% (triticale intercrops) and 86.5% (oat solo). The
values of spike weight and seed weight was different among the cereal
species and higher in intercrops than in monocrop system of cultivation.
However, only for rye in mixture with pea, harvest index (78.8%) was higher
than in monocrops of rye (77.0%). Harvest index of pod variate in ratio
50.3% (pea solo) and 69.5% (in intercrops pea + rye). The values of pod
weight and seed weight pod-1 was different and higher in intercrops than in
monocrops system of cultivation. Harvest pod index of peas was significantly
higher in mixture with each small grains species genotypes than in pea?s
monocrops. On the base of result we can conclude that intercropping cereals
+ peas, have positive effect on spike and pod characteristics which values
were higher in intercrops than in monocrops. |
