ABSTRACT: In January 2003, in the Animal Production Research Unit, Lara, Venezuela, duckweed (Lemna minor) was cultured in microlagoons to determine biomasa production. Three experiments (E) were carried out with a totally randomized design: E1 (T0 = 30 g of duckweed, T1 = 30 g of duckweed and 32 g of fertilizer), E2 (T0 = 5 g of duckweed, T1 = 5 g of duckweed and 32 g of fertilizer), with 25 repetitions per treatments; and E3 (T0 = 5 g of duckweed, T1 = 5 g of duckweed and 20 g of fertilizer, T2 = 5 g of duckweed and 30 g of fertilizer, and T3 = 5 g of duckweed and 40 g of fertilizer), with 15 repetitions per treatment. The duckweed gave higher yieldeds when fertilized, and the yields depended of the quantities of vegetative material and fertilizer added to the microlagoon.
