Alley cropping systems: key objectives

2017
In an alley cropping system, trees are multifunctional: the aim is to provide a range of ecosystem services alongside wood and fruits. These include shelter for crops, host beneficial organisms, increase soil fertility and carbon storage, mitigate climate change, and provide protection against soil erosion.

Alley cropping—soil productivity and nutrient recycling

Forest Ecology and Management, 1997
Abstract In the past few decades there has been growing concern about the exhaustibility of non-renewable soil resources in developing countries in the tropics to meet the needs of present and future generations. Land degradation is a major problem in many parts of the tropics, including subSaharan Africa, mainly owing to overexploitation of ...

Does pollarding trees improve the crop yield in a mature alley‐cropping agroforestry system?

Journal of Agronomy and Crop Science, 2020
AbstractIn agroforestry systems, the canopy of maturing trees progressively reduces the radiation available for the crop. Tree management practices such as pollarding can be used to restore the crop light availability. We monitored durum wheat, barley and pea yields during three consecutive years in an alley‐cropping agroforestry system with hybrid ...

Alley cropping: past achievements and future directions

Agroforestry Systems, 1993
There is a need to develop viable farming systems for tropical uplands dominated by low-activity clay soils; such systems should ensure sustained crop production while protecting the soil resource base. Alley cropping has the potential to meet this need.

Alley Farming: A Sustainable Technology for Crops and Livestock Production

Journal of Sustainable Agriculture, 2006
ABSTRACT Sustainable increase in agricultural production was achieved in the past through the use of bush-fallow farming system. Extensive land use due to urbanization, increase in population and high farming population has led to reduction in fallow period.

Alley cropping with Senna siamea in South-western Nigeria: I. Recovery of 15N labeled urea by the alley cropping system

Plant and Soil, 2001
Improved cropping systems with in-situ production of organic matter require the input of additional inorganic N to maintain crop production in a sustainable way. For proper management of this fertilizer-N, it is necessary to quantify how the applied fertilizer N is used by the various components of the system and by the system as a whole. The fate of a

Understory management in alley cropping systems in France

2017
If trees and crops are the productive components of the agroforestry alley cropping systems, a third component must be considered: the non-crop vegetation at the tree strip. This understory vegetation is the consequence of the difficulty of cultivating soil very close to the trunks without damaging trees.

From alley cropping to cashew farms

2004
Flores is an island at the heart of the small archipelago between Bali and Timor. The eastern part of this archipelago is an Indonesian province called Nusa Tenggara Timur, and Flores is part of it. This chapter examines the adoption of cashew as a new tree crop in the Sikka district, an already densely populated and cultivated region of Flores. Cashew

Systems thinking and practice for alley cropping research

1997
Systemic and reductionist methodologies were applied to explore alley cropping systems. Alder (Alnus rubra) and black locust (Robina pseudoacacia) are grown as green manure in sweet corn production systems. Our research includes the study of biological, ecological, and social interactions.

Gewasopbrengst in jonge silviculturele alley cropping systemen

In silviculturele agroforestry systemen worden bomen gecombineerd met akkerbouwgewassen. In de gematigde streken kan dit resulteren in een gedaalde gewasopbrengst en/of gewijzigde gewaskwaliteit nabij de bomen. Één van de basisprincipes van agroforestry is dat deze opbrengstreducties op zijn minst gedeeltelijk gecompenseerd worden door de productie van
