MANAGING THE TREE UNDERSTOREY Opportunities for crop diversification

, 2018
AFINET Factsheet exploring opportunities for using the area under the trees as a productive part of the system.Planting trees into arable or vegetable fields means that land is taken out of annual production; depending on the design of the system, this could be up to 25% of the cropping area.

Perennial clovers and ryegrasses as understorey crops in cereals [PDF]

, 2003
Perennial crops undersown in cereals provide ground cover from harvest of the cereal crop to sowing of the next crop. Such cover crops can e.g. reduce soil erosion, nutrient leaching and N fertiliser requirements of the succeeding crop. The objective of this thesis was to develop guidelines on how to prevent grain yield losses due to competition from ...
