I'm looking for case studies on Land Equivalent Ratio applied to agroforestry systems to develop learning applications to agronomy students. I would appreciate suggestions of published raw data to create exercises with real situations.

An example of publication:

NEWMAN, S. M. A pear and vegetable interculture system: land equivalent ratio, light use efficiency and productivity. Experimental agriculture, v. 22, n. 4, p. 383-392, 1986.
