Agronomy Journal, 2016 Intercropping has been shown to be land use efficient, but there is a large variation in the land equivalent ratio (LER) among studies. We used quantile regression to estimate the effect of temporal niche differentiation and its interaction with other key characteristics of intercropping, i.e., crop type combination, N fertilizer, relative density, and

A General form of the ‘Land Equivalent Ratio’
Experimental Agriculture, 1984 SUMMARYThe Land Equivalent Ratio (LER) concept is presented and interpreted. Several different intercropping systems are considered and the need for methods to evaluate them is discussed. A general form of the LER is proposed for the evaluation, in particular, of a system that combines two intercrops having different yield proportions.

Agriculture (Switzerland), 2019 The alley-cropping systems (ACSs), which integrate parallel tree strips at varying distances on an agricultural field can result, complementarity of resource use, in an increased land-use efficiency. Practitioners’ concerns have been directed towards the

Productivity and Land Equivalent Ratio of Intercropping Cotton with Some Winter Crops in Egypt
American Journal of Experimental Agriculture, 2016 Two field experiments were carried out at Research Station, El-Sharkia Governorate, ARC, Egypt during 2009/2010 and 2010/2011 seasons to inv estigate the effect of relay intercropping cotton with some winter crops as compared with sequential solid ...

Proxydetection of the impact distance of trees on crops: An indicator of the Land Equivalent Ratio?
Agriculture, Ecosystems and EnvironmentHighlights: • Crops yield and leftovers were scaled up to the field-scale. • Using spectral images throughout the crop cycle improves productivity predictions. • The distance of influence of trees on crops can be measured by proxydetection and reveals the Land Equivalent Ratio.Abstract: Faidherbia albida is known to affect the yield of various crops ...

Intercropping of some Faba Bean Cultivars with Sugar Beet using Different Irrigation Intervals under Sprinkler System in Sandy Soils [PDF]
Journal of Plant Production, 2020 A two-year field experiment was carried out at Ismailia Agriculture Research Station, ARC, Egypt during 2018/19 and 2019/20 seasons to assess the effect of two deficit irrigation intervals (irrigation every 4 (I2) and 5 days (I3), compared to irrigation ...
