Abstract

This experiment was conducted with the objective of identifying the main nutrient deficiencies that can limit the growth and nitrogen fixation of macrotiloma (Macrotyloina axiliare (E. Mey) Verdc). The legume was grown in a Dark Red Latosol from Itapetininga located in the South Region of São Paulo State, Brazil. The study was done in a greenhouse at the Instituto de Zootecnia, in Nova Odessa, State of São Paulo, from October 1984 to March 1985. Ten treatments were arranged in a randomized complete block design with four replications. An omisson type of treatment arrangement allowed to study the effects of lime, P, K, S, Cu, Mn, Zn and Mo. The results showed that: a) phosphorus deficiency was the most limiting factor for legume establishment, growth and nitrogen fixation; b) lime omission reduced significantly (P < 0.05) the dry matter yield, the total amount of nitrogen and nodulation; c) manganese concentration in the herbage was very high iii the treatments without lime application; d) zinc omission resulted significant decrease (P < 0.05) in the concentration of this micronutrient in the herbage; e) the omissions of K, S, Cu and Mo did not change significantly (P > 0.05) any of the studied variables.
