Title
Productivity of Annual Legume-Grass Mixtures According to Interspecies Competition
A. Reneva Iu 2014
Other claims from this paper (18)
- Intervention effect In a pea and barley mixture the LER was 1.18, a productivity advantage over pure sowing.
- Intervention effect Vetch, lupine and barley mixtures are not effective, because their components give higher productivity in single-crop sowing.
- Mechanism High productivity of the pea and barley mixture is attributed to less intensive interspecies competition.
- Observation The competitive ratio of pea in the pea and barley mixture is 0.97.
- Observation The competitive ratio of barley in the pea and barley mixture is 1.03.
- Observation A slight aggressivity from cereals was noted in the mixtures.
- Observation In other mixtures the competitive ratios of cereals reach 1.17 to 1.24.
- Recommendation The level of competition in legume-grass mixtures should be regulated by changing component ratios and selecting cultivars.
- Association Vetch cultivar Vera is highly competitive to cereals, unlike cultivar Liudmila.
- Association Mixtures with vetch Vera are less yielding per feed grain.
- Recommendation Liudmila vetch and Samarets pea are more suitable for cultivation in agrophytocenoses with two species.
- Intervention effect Pea and barley mixtures are not as effective in land use as pure sowings under agrometeorological conditions unfavourable for pea.
- Observation The land equivalent ratio of the legume-grass mixtures varied from 0.87 to 0.97.
- Observation Interspecies competition in the legume-grass mixtures was very high in the circumstances studied.
- Observation Barley was the most competitive component in the mixtures, with CR 3.33 to 23.06.
- Association At 60 kg/ha nitrogen the cereal almost completely displaces the legume component, which increases mixture productivity.
- Association Increasing the pea seeding rate lowers interspecies competition on a nitrogen-free background.
- Association Increasing the pea seeding rate lowers sowing productivity.
