TLDR
A survey of the available information reveals that most of the agroforestry species (AF species) have negative allelopathy effects on food and fodder crops as discussed by the authors, therefore, it is desirable to do further research in this direction so that AF species with no or positive allelopathic effects on the companion crops may be promoted for agro-forestry programs.Abstract:
Agroforestry is a modern tool to develop sustainable land use and to increase food production by growing woody species (trees, shrubs, palms, bamboos, etc.) with agricultural crops and/or animals in some form of spatial arrangement or temporal sequence. Because these species co-exist with the agricultural crops, their allelopathic compatibility may be crucial to determine the success of an agroforestry system. A survey of the available information reveals that most of the agroforestry species (AF species) have negative allelopathic effects on food and fodder crops. Therefore, it is desirable to do further research in this direction so that AF species with no or positive allelopathic effects on the companion crops may be promoted for agroforestry programs. As AF species remain a part of the agroecosystem for a longer period, and most of them produce a large amount of leaves and litter, their allelochemicals may play an important role in developing an eco-friendly pest management strategy. Besides these generally studied aspects of allelopathy, some comparatively newer aspects of research have been identified, such as evaluation of qualitative yield of agroforestry systems, selective behavior of the allelochemicals, effect on soil quality, and the role of tree allelochemicals in animal and human nutrition. If given due consideration, allelopathy could play a pivotal role in conservation of the highly threatened environment, biodiversity, natural resource base, and making agriculture more sustainable through broadening the scope of agroforestry.read more

TL;DR: Future research on biophysical interactions should concentrate on exploiting the diversity that exists within and between species of trees, determining interactions between systems at different spatial and temporal scales, and improving understanding of belowground interactions.

TL;DR: Combined application of allelopathic extract and reduced herbicide dose (up to half the standard dose) give as much weed control as the standard herbicides dose in several field crops, and lower doses of herbicides may help to reduce the development of herbicide resistance in weed ecotypes.

Allelopathy in agroecosystems: an overview.
TL;DR: Allelopathy plays an important role in the agroecosys-tems leading to a wide array of interactions between crop-crop, crop-weed and tree-crops, which are harmful to the receiver plants but provide a selective benefit to the donor.

TL;DR: In California the annual vegetation adjacent to natural-ized stands of Eucalyptus camaldulensis often is inhibited severely, and water-soluble toxins found in the litter inhibited herb growth in laboratory, green- house, and field experiments.

Role of phenolic substances from decomposing forest litter in plant–soil interactions
TL;DR: Soil phenolic substances directly affect bacteria, the development of mycelia and spore germination of saprotrophic and mycorrhizal fungi, and the germination and growth of higher plants (Hartley & Whitehead 1985).
