The relative growth rate (RGR) of establishing leucaena (Leucaena leucocephala cv. Peru) sown at different times in spring and summer was studied. Early growth was best related to minimum air temperature which accounted for 74% of the variation in RGR. Maximum air temperature and solar radiation had little influence on RGR. The results indicate that leucaena should be planted when the mean daily minimum air temperature is likely to be above 15°C.
