AbstractA study was conducted to evaluate growth characteristics of broom snakeweed plants at three locations on the New Mexico State University Ranch, located about 32 km north of Las Cruces. Twenty individual plants were marked with wooden stakes at each location. Height and average diameter of each plant were measured biweekly during the growing season in 1977 and 1978. Measurements of the same attributes were taken biweekly on ten additional plants at each location in 1977, These plants were harvested and hand-separated into green and brown leaves and branches and flower parts, oven-dried and weighed. Regression analysis, used to predict biomass of snakeweed and component parts from height, diameter and volume measurements, indicated that these variables accounted for much of the variations in the models obtained. Further analysis of variance generally showed that differences among sites and dates were significant (P<.05 indicating="" that="" there="" was="" considerable="" variation="" in="" growth="" form="" among="" plants="" within="" and="" between="" growing="" seasons.="" observations="" also="" suggested="" adequate="" timely="" precipitation="" especially="" july="" august="" significantly="" influenced="" the="" of="" snakeweed="" during="" both="">
