Abstract

BATALHA, L. S.; SILVA FILHO, D. F. da  and  MARTIUS, C.. Using termite nests as a source of organic matter in agrosilvicultural production systems in Amazonia. Sci. agric. (Piracicaba, Braz.) [online]. 1995, vol.52, n.2, pp. 318-325. ISSN 0103-9016.  http://dx.doi.org/10.1590/S0103-90161995000200019.

The growth of two annual crops, okra (Abelmoschus escutentus) and egg-plant (Solatium melongena) and one perennial crop, andiroba (Carapa guianensis, a native forest tree of Amazonia) under different treatments with organic manure derived from termite nest material of wood-feeding Nasutitermes species was tested (randomized block design). The use of 25-100 g of nest material gave no significant increase in okra productivity, and 25-200 g gave no significant response in andiroba. The combined use of NPK with 200 g of nest material gave a significant higher production in egg-plant (total number and total fresh weight of fruits) when compared to the control (without fertilizer) and to the treatment with NPK only.The results suggest the possibility to use termite nest material to enhance crop production in Amazonia, particularly in combination with low amounts of mineral fertilizer. Research lines for further investigations are outlined.
