A comparative study was made in 1964 of the vertical paint quadrat, inclined point quadrat and dry-weight estimation (hand separation) methods of determining botanical composition of lour different pasture mixtures. The weight estimation method was the standard with which the other methods were compared. There were no significant differences between the percentage contribution of pastures obtained by the two point quadrat methods, but significant difference was found only in Ky 31 Fescue of experiment 2nd. The percentage contribution from the point quadrat methods and weight estimation were closely associated giving highly significant and positive correlation coefficients in this experiment. The results indicated that the two methods, vertical and inclined, gave similar and equally reliable estimates of the percentage contribution of pasture mixtures. However, when records were kept of times taken for the use of two point quadrat methods, the vertical point quadrat method was a Little more rapid than the inclined point quadrat method.
