Biomass is the result of the solar energy transformation into chemical energy. The production of plant biomass is very important for animal feed and therefore for the production of products for human consumption. Therefore, the objective of this work was to have an equation that indicates the growth of Tanzania's re-sprouting in the rainy season. On the farm is the plot established for 4 years with Tanzania grass in soil enriched with rabbit manure at a rate of 10 kg/m2 once a year 30 days before rains. The re-sprouting measurements were made randomly, with tape measure from the previous cut level to the average forage height of a 1.0 m2 frame, every 10 days after the cut and up to 60 days, and 10 measurements were taken per time. The data collected from the grass underwent a mathematical procedure to typify its growth curve with a high degree of accuracy, this method known as Gauss Jordan. The average growth and DS in cm recorded for days 10, 20, 30, 40, 50 and 60, was 49±7.4, 69±8.9, 82±10.3, 101±8.9, 154±11.4 and 191±7.4 respectively. A second-degree polynomial equation and an R2 coefficient of determination of 0.98% were obtained.
