Abstract

The objective was to verify the production of litter in two plantations of E. urocam and E. urograndis inserted into the Cerrado Biome, Aliança do Tocantins - TO. The study was conducted at the farm Nossa Senhora Aparecida, Aliança do Tocantins - TO, under the coordinates 11 "21'53 S and 49" 02'54 W. Ten collectors of 1 x 1 m were randomly installed in each plantation. The collectors were supported by piles with 0.80 m off the ground, which were monitored monthly during the period May 2015 to April 2016. The collectors were supported by 0.80 m height piles, which were monitored monthly during the period from May 2015 to April 2016. The samples were dried and separated into leaf and timber material fractions. The average production of total litter between the two stands showed quite varied with an annual production of 3274.5 kg ha-1 in the E. urocam stand and 3523 kg ha-1 in the E. urograndis stand. The most representative fraction of the total litter found in both stands studied consisted of leaves that make up 51.2% of the material deposited in the collector while the timber material fraction contributed 48.8%. In both stands, the greatest contribution of leaves occurred in the period of highest rainfall (May, November and December 2015 and January to April 2016).
