Abstract

A field experiment was carried out at the Instituto de Zootecnia, State of São Paulo, to study the effects of liming and micronutrients applied to an Ultisol for the growth of Centrosema pubescens Benth. Four liming rates (0; 1.2; 2.4 and 3.6t/ha) were combined with the application or not of molybdenum or boron + copper + zinc. Liming was the main plot and micronutrient combinations were subplots which were assigned in randomized complete block design, with four replications. Fourteen harvests were performed in the five years of experimentation. Forage yield and the total amount of crude protein significantly (P <0.01) responded to lime, to molybdenum and to boron+ copper+zinc, in the first harvest. These effects were also evident during the first year after plant establishment. Liming did not affect these plant responses in the following years, whereas molybnedum did. Changes in forage nutrient concentrations are discussed as a consequence of liming and micronutrients applications, changes in soil fertility as result of liming are also presented.
