Description
Canopy growth is related to solar radiation intercepted (PARa), (Greenwood et al., 1986; Gosse et al., 1986). The canopy interception efficiency ( i: i = P ARa/P ARc) is related to leaf area index (LAI). In spring, for grasses i: i = 70 % when LAI = 2 (Lemaire, 1985). The faster the LAI extension rate is, the greater the dry matter yield is. We study nitrogen and grassland type effects, with phosphopotassic soil fertility level and botanical criterion.
