Yield ultimately decides how effective any weed control measures have been. With the use of herbicides it is desirable to know the composition of the weed population in the field in order to decide what chemical will effectively control the predominant species. This assessment may be done qualitatively or quantitatively. Qualitative methods are easier and quicker to use but quantitative methods are more precise and are therefore more valuable for a critical study of the weed problem. Two quantitative methods of weed analysis were compared-the line transect intercept method and the list area quadrat method. Both methods were comparable in the way they brought out the most predominant species, but the quadrat gave a fair representation of the few scattered species as well. The line transect was found to be much quicker to use.
