Abstract

An experimental work was carried out at
"Niña Bonita" Pasture and Forage Station of Bauta, in order
to achieve high forage production based on triticale by using
minimum nitrogen doses. It was made on a Lixic Ferralic
Nitisol with arbuscular mycorrhizal fungal inoculations
(AMF). Treatments consisted of AMF inoculation and
non-inoculation as well as varying N doses (0, 50, 100,
150, 200, 250 and 300 kg ha-1), with a fixed bottom of 54
and 70 kg ha-1 of phosphorus and potassium, respectively.
Evaluations were performed to leaf rates (% N, % P and
% K), fungal variables, N, P and K extraction (kg ha-1),
raw protein (%), mycorrhizal efficiency (%), dry forage
mass (kg ha-1), apparent recovery efficiency (kg kg-1) and
partial factor productivity, besides using ANOVA statistical
analyses with one-way classification model to the original
data. In every case, the best fitting models (dose-yield) were
chosen to estimate optimal N doses with and without AMF,
followed by the first derivative criteria to find the respective
optimum ones. Results showed that AMF application allows
reducing N doses to 50 and 100 kg ha-1, achieving a dry
mass production of 6185 kg ha-1 with 11,75 % raw protein;
leaf rates of 1,94 % N, 0,23 % P and 30 % K, indicating the
adequate forage quality produced.
