Description

Climatic and edaphic aspects have been worldwide con­sidered as the main limiting factors for forage production. Plant distribution is highly influenced by edaphic and cli­matic effects (Humphreys, 1981). In the same way researchers states that the rate of growth of pasture plants is expressed in dry matter production which is a function of the net rate of photosynthesis influenced by climatic factors (Whiteman, 1980). The basic climatic features were put togheter to be expressed as the Multifactor Growth Index which relates light, tempera­ture and moisture affecting the growth of forage plants (Fitzpa­trick & Nix, 1970). Present work made an ecological approach to find out optimum sites within Sao Paulo State to grow c.a. 20 grasses and 12 legumes using climatic and edaphic features.
