The sole crop systems with which intercropping must be compared to satisfy these objectives are defined. Evaluation in relative, absolute, monetary and nutritional units is discussed and some aspects of presenting intercropping data in graphical form are illustrated publisher: Cambridge University Press date: 1985 type: Article type: PeerReviewed format: application/pdf language: en identifier: http://oar.icrisat.org/7466/1/ExpAgric_21_119-133_1985.pdf identifier: Willey, R W (1985) Evaluation and Presentation of Intercropping Advantages.
