When the growth parameters in polycultures
of rainbow trout and brown trout are considered, it was determined that the growth rates were not statistically different between rainbow trout monoculture and rainbow trout G75K25 and G50K50 groups, however rainbow trout in G66K34 experienced statistically significantly less growth when compared to others (p<0.
To assist ACICAFOC (Asociacin Coordinadora Indigena y Campesina de Agroforesta Comunitaria Centroamericana) in the design, planning, technical and financial implementation, monitoring of all measures and activities of the above program, including the diversification of lowspecies agricultural production systems and the consolidation of polycultures
which aims to improve market access for the resulting agricultural products and to conserve and spread endemic and locally adapted species.
Several indices or indicators have been used in both the agronomic evaluation of biological productivity and in the economic efficiency of polycultures
(Bezerra Neto et al.
In this paper, we focused on the performance of Horizontal CW at pilot scale planted with polycultures
of the tropical plants Gynerium sagittatum (Gs), Colocasia esculenta (Ce) and Heliconia psittacorum (He) treating LL under tropical conditions.
The Land Equivalent Ratio (LER) is defined as the relative area required for polycultures
to afford the same yield as monocultures (ALTIERI et al.
Integrated Forest Gardening: The Complete Guide to Polycultures
and Plant Guilds in Permaculture Systems follows the permaculture movement and the idea of creating 'plant guilds', and offers the first book about these guilds, form what they are and how to design them to developing perennial agricultural systems that thrive without expensive inputs.
Farmers are rapidly changing to no-till methods and employing various polycultures
in their cropping systems to revive the natural soil-building process that occurs when a specific set of plants are grown together.
This strategy establishes polycultures
that collectively harvest more rain and sun, and use proportionately less groundwater and fossil fuel.
In Costa Rica, tropical reforestation has shifted from an emphasis on exotic monocultures for timber production to assessing the performance of native species polycultures
to restore biodiversity and ecosystem services.
In just the last century, thousands of heirloom varieties of fruits and vegetables and heritage breeds of livestock have disappeared as the demands of industrial agriculture shrink traditional farming polycultures
The effect of common carp Cyprinus carpio (L) and mrigal Cirrhinus mrigala (Hamilton) as bottom feeders in Indian major carp polycultures
As many peasant farmers commonly manage polycultures
and/or agroforestry systems, their knowledge and practices could provide a valuable source of information for agriculture in times of climate change.
