In the study plant samples were taken at weekly intervals between the onset of spring re-growth and flowering stage, and at fortnightly intervals starting from flowering until the beginning of winter far measurements and analyses of plant height, aboveground biomass, belowground biomass, leaf ratio, dry matter content, crude protein content, crude cellulose content calcium content, potassium content, magnesium content and K/(Ca + Mg). All the parameters were regressed against time, plant height and aboveground biomass. All the parameters regressed varied significantly (P< 0.01 or P< 0.05) with time and plant height. Whereas similar relationships were recorded with aboveground biomass except for belowground biomass, Ca and K contents. Analyses and regression graphics are presented and discussed in the paper.
