During three seasons of 1966 an experiment was conducted to study the regrowth of red clover as related to various morpholo gical and phisiological variables.
Maximun yield of the various components were not obtained at given stages of morphological plant development or daysof regrowth for different seasons of the year. Thestage offlowering was not a good reference for cutting dates in spring and fallo Entirely different trends of root car bohydrates ocurred for each season. On the other hand, leaf area index (LAI) and plant height showed high correlations with dccumulative yields of dry matter, crude protein, and digestible dry matter per hectare.
Although it is possible to give definit conclusions for the best stage of growth forcutting red clover, it seems that the best stage varies for different seasons of the year.
