Description:	Experimental methods and analytic procedures in intercropping research are not as much developed as in sole crop research, although some of the techniques of sole cropping can be extended to intercropping. The research strategy for yield improvement in intercropping should be same as for sole crops, requiring studies in crop physiology as well as on various agronomic factors. The intercrops can be evaluated by scale neutral indices such as land equivalent ratio, area-time equivalent ratio or combining yields by monetary value, protein, calories etc. Evaluation of yield stability is of utmost importance for subsistence farmers, and in this contex multilocation tests are emphasised. Some aspects related to selection of treatments, particularly of sole crops, factorial arrangemens for estimating independent and interaction effects, plot size, minimum data sets to be recorded and standardisation and analysis of results are discussed briefly.
