In the recent past, significant advances in the production technologies have taken place necessitating suitable modifications in the existing designs and methodology for data analysis. Adoption of modern techniques in dry land agriculture especially in situations under intercropping has led to suit the needs of designs and analysis of experiments. A few excellent status review of this area of research is available. However, information on plot technique for field experimentation on intercrop system as well as critical stages of competition of crops involved in intercropping systems are lacking. Such information has its own significance in planning of experiments on intercropping systems. Critical stage of competition has direct relevance with productivity of the component crops of the systems. Keeping this in view, the study was undertaken.
