dc.description.abstractThe, the aim of this study was to evaluate the residual effect of phosphorus on intercropping of forage in the off-season. The experimental design was randomized blocks in factorial scheme 4 x 2 + 1 and four sources of phosphorus (Reactive Phosphate Bayóvar - 29% P2O5 total (FR), Monoammonium Phosphate 52% P2O5 (MAP), Single Superphosphate - 18% P2O5 (SS) and the Triple Superphosphate 42% P2O5 (ST)) and two application forms (broadcasted and line), plus an additional treatment without phosphorus fertilization with four blocks. The experiment was carried out in the off-season in area planted with soybean crop in 2014/2015. The source treatments and application forms were applied in soybeans. The residual effect of phosphate fertilizer provided increments in growth and biomass production of forage sorghum especially for phosphorus acidulous sources (SS and ST) applied at broadcast. The lower P content in the tissue of plants fertilized with SS and TS may be attributed to the diluting effect of this nutrient in the plant, as it achieved the highest biomass production. The ST application also favored the dry matter production of piatã grass. In the depth of 0 to 5 cm was higher P content with FR application, but biomass production was low, a factor that may be related to the P linked to Ca overestimation by extractor Mehlich I.pt_BR
dc.description.resumoObjetivou-se com este estudo avaliar o efeito residual do fósforo em cultivo consorciado de forrageiras na safrinha. O delineamento experimental foi em blocos ao acaso em esquema fatorial 4 x 2 + 1 sendo, quatro fontes de fósforo (Fosfato Reativo Bayóvar – 29% de P2O5 total (FR); Monoamônio Fosfato 52% de P2O5 (MAP); Superfosfato Simples – 18% P2O5 (SS) e o Superfosfato Triplo 42% P2O5 (ST)) e duas formas de aplicação (a lanço e na linha), mais um tratamento adicional sem adubação fosfatada, com quatro blocos. O experimento foi realizado na safrinha em área cultivada com soja na safra 2014/2015. Os tratamentos das fontes e formas de aplicação foram aplicados na soja. O efeito residual da adubação fosfatada proporcionou incrementos no crescimento e na produção de biomassa do sorgo forrageiro, principalmente para as fontes aciduladas de fósforo (SS e ST) aplicadas a lanço. Os menores teores de P no tecido das plantas adubadas com SS e ST pode ser atribuído ao efeito de diluição desse nutriente na planta, já que obtiveram as maiores produções de biomassa. A aplicação com ST também favoreceu a produção de massa seca do capim-piatã. Na profundidade de 0 a 5 cm houve maior teor de P com aplicação de FR, porém a produção de biomassa foi baixa, fator que pode estar relacionado com a superestimação de P ligado ao Ca pelo extrator Mehlich I.pt_BR
