Abstract

OLIVEIRA, P.S.R.; DEMINICIS, B.B.; CASTAGNARA, D.D.  and  GOMES, F.C.N.. Agronomical characteristics of the mombaça grass fertilized with phosphorus in sandy and loamy soils. Arch. zootec. [online]. 2012, vol.61, n.235, pp.397-406. ISSN 1885-4494.  https://dx.doi.org/10.4321/S0004-05922012000300008.

This study was conducted to evaluate, in two cuts, the effects of Phosphorus rates on tillering, dry matter production of leaves and stems, and the aerial dry matter production of Panicum maximum 'Mombaça' cultivated in jars with Eutrophic Red Yellow Latosol and red-yellow argisoil. The experiment was led under controlled environment in Experimental farm Marcello Mesquita Serva, of UNIMAR, in Marília-SP, Brazil. A factorial design 4 x 2, completely randomized with three repetitions was used. The treatments were four doses of P as triple superphosphate (0, 300, 600 and 900 mg P kg^-1 of ground). There was significant interaction with the tiller number. Considering the dry matter aerial production the most technical appropriate dose was 300 mg P/kg of ground.

Keywords : Dry matter; Panicum; Aerial part; Tillers.
