Biomass estimation for native perennial grasses in the plain of Mendoza, Argentina

Perennial grass response to 10-year cattle grazing in the Mendoza plain, mid-west Argentina

“…Because basal area proved to be a good predictor of biomass for the grasses included in the present study (Guevara et al, 2002), similar trends were observed when distance from water was regressed on basal area or above-ground biomass.…”

A non-destructive and rapid method to estimate biomass and aboveground net primary production in arid environments

“…Equations developed for other ecosystems presented parameters for a single species or single life form (i.e. Guevara et al, 2002;Williamson et al, 1987) or used allometric equations (which typically differ among life forms) that must be scaled with density to obtain ecosystem-level biomass (i.e. Adler et al, 2004;Johnson et al, 1988;Na´var et al, 2004;Rittenhouse and Sneva, 1977;Williamson et al, 1987).…”

Effect of mulching practices on growth and yield of forage crops under rainfed ecosystem

“…(66.40 and 88.20 cm at final observation during winter and summer season, respectively) was recorded with Setaria anceps followed by Panicum maximum and Brachiaria brizantha. With the changes in forage types variation in plant height are well known because size of meristematic zone and rate of cell production are mainly contributed in increasing height and those are become differed within different types of plant, it is the consequent of variations in height of the different grasses (Guevara et al, 2002). Mulching had significant effect on plant height in all dates of observations except at 15 DAI during winter (Table 1).…”
