Girth and height measurements of a number of young rubber plants of several clones were recorded for a period of over six months. The effect of weather factors; rain, humidity, pressure, wind, sunshine and temperature on the growth parameters were investigated using regression methods. Seasonal changes in girth and height were also studied.
