Abstract

The experiment was conducted under greenhouse conditions, in Jaboticabal, state of São Paulo, Brazil, to evaluate the contents of total non-structural carbohydrates (TNC) of Tanzania grass, submitted to five levels of N (0, 75, 150, 225 and 300 mg.dm^-3 of soil) and evaluated at four periods (20, 30, 40 and 50 days after emergence). The experimental design consisted of a completely randomized block with three replications, in a factorial arrangement of 5 x 4. The plants were cut at soil level and the aerial part of plants were separated from the root system. Contents of starch, soluble carbohydrates (SC) and TNC were evaluated in the aerial part and root system. At the stem basis the contents of starch, SC and TNC increased according to period nitrogen doses and root system
