Abstract
The biomass yield and the crude protein (CP) content of temperate agroforestry-grassland were compared with that of a treeless control between 2017 and 2021. The single factor cropping system did not determine differences in yield nor CP content, while significant interactions with other studied factors occurred. At 1 m from the field edge, grassland yield was significantly lower in both the agroforestry system and the treeless control than at the other distances studied (4, 7, and 24 m). Overall, grassland yields were similar in agroforestry and control. The CP results were inconclusive. The highest, although not significant, CP levels were found in the agroforestry variant 1 m distance from the tree strip. Our study shows that due to edge effects on biomass yields, which may also occur in the treeless control, sampling of identical distances in agroforestry and control are necessary.
期刊介绍:
Agroforestry Systems is an international scientific journal that publishes results of novel, high impact original research, critical reviews and short communications on any aspect of agroforestry. The journal particularly encourages contributions that demonstrate the role of agroforestry in providing commodity as well non-commodity benefits such as ecosystem services. Papers dealing with both biophysical and socioeconomic aspects are welcome. These include results of investigations of a fundamental or applied nature dealing with integrated systems involving trees and crops and/or livestock. Manuscripts that are purely descriptive in nature or confirmatory in nature of well-established findings, and with limited international scope are discouraged. To be acceptable for publication, the information presented must be relevant to a context wider than the specific location where the study was undertaken, and provide new insight or make a significant contribution to the agroforestry knowledge base
