TY - JOUR N2 - It is proposed that two distinct objectives should be recognized in the evaluation of intercropping advantages: (i) a biological objective to determine the increased biological efficiency of intercropping and (ii) a practical objective to determine the advantages that are likely to be obtained by a farmer. 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 AV - restricted A1 - Willey, R W TI - Evaluation and Presentation of Intercropping Advantages UR - http://dx.doi.org/10.1017/S0014479700012400 JF - Experimental Agriculture SP - 119 Y1 - 1985/// ID - icrisat7466 EP - 133 SN - 0014-4797 VL - 21 PB - Cambridge University Press IS - 2 ER -
