Abstract

Greenhouse experiments were carried out at the Instituto de Zootecnia, Nova Odessa, State of São Paulo, Brazil, to identify the main nutritional deficiencies of three soils for the establishment, yield and nitrogen fixation by galaxia (Galactia striata (Jacq.) Urb.). The effects of lime, P, K, S, Mo and (B + Cu + Zn) were studied m a omission type of treatments arranged in a randomized complete block design with four replications. The results showed that the legume was not established when no-fertilizer was applied. Phosphorus was the most limiting nutrient for the legume in the three soils. No-lime treatment in the Quartzous Sand soil decreased yield, nodule weight, N, Ca, and Mg percentages in the plant tissue, and N content in galaxia. Potassium omission to the Quartzous Sand soil reduced nodule weight of the legume, and that omission decreased the K percentage in the plants grown in all soils. Low Zn concentration was observed in galaxia when the micronutrient was not applied to the three soils. Nitrogen content m galaxia was decreased by the Mo omission to the Quartzous Sand and Dark -Red Latosol soils.
