Behaviour of temperate green manure species in a mountain region of the Rio de Janeiro State, Brazil

Abstract

The objective of this work was to evaluate the behaviour of temperate green manure species in an Inceptisol with two different fertility levels, in an area of high elevation (1,100 m). Two field experiments were carried out in Nova Friburgo County, Rio de Janeiro State, Brazil, with the following species: Avena strigosa Schieb., Lollium multiflorum Lam., Lathyrus sativus L., Vicia sativa L., Vicia villosa Roth, used in the 2^nd experiment only, Ornithopus sativus Brot., Lupinus luteus L., Lupinus albus L. cv. Comum, cv. Multo Lupa Doce and cv. TRM 881, Trifolium repens L., Trifolium pratense L. cv. Achylesmarium and Trifolium vesiculosum Savi cv. Jacuí 52. The experimental design used was a randomized complete block design, with three replications. The species of best performance in relation to the above ground dry matter and total N on a soil with good fertility were L. albus (for all three cultivars used), L. luteus, V. sativa and A. strigosa. On a soil with low P, Ca and Mg, the best plant performances for above ground dry matter and total N were L. albus (all three cultivars) and A. strigosa
