Allelopathy Field Research Methods. 1. Crops-weeds interactions

Allelopathy techniques usually used under field conditions, may help in understanding and identifying allelopathic species and their harmful influences on other species are presented and discussed. New suggested technology enables the students and researchers to better understand the allelopathy mechanism in field are also included and explained. Suggested methods and presented techniques will help in separating the allelopathy from competition and allow better understanding of differences and similarities between both components of plants interference in nature. Advantages and weaknesses of each technique are mentioned, steps to overcome any problems in implementing each method are also provided and precautions are given where necessary. Alternatives to each technique that enable the researchers to confirm results obtained are also given.
