Resumo: | It is reported a research work done with the objetive to investigate the effect of N, P, K, Ca and Mg and its interact on Peanut Crop (Arachis hypogaea L.). The work was done in soils classified as Itaguai and Ecologia series, covering most of the Km 47 area and Baixada de Sepetiba. In the studied soils, relating to the Itaguai series, it was found the lime effect, being that in one of the soils of this series was also found a favorable effect of the magnesium in increasing the peanut production. It was still found the negativeness of potassium in one of the studied soils of Itaguai series, when added lime, magnesium and nitrogen it neutralized the beneficial action of these minerals in the productivity. In the soils of Ecology series, only the effect of magnesium was statistically significant. However the magnesium showed positive reaction when added to the phosphorus and to the potassium, while the lime showed negative reaction in the production, though without statistic significance. |

Os trabalhos foram instalados em solos mapeados como das séries Itaguaí e Ecologia, dominantes na área do Km 47 e Baixada de Sepetiba. Nos solos estudados, pertencentes à série Itaguaí, foi positivado o efeito da cal, sendo que em um dos solos desta série houve, também, efeito favorável do magnésio no aumento da produção do amendoim. Sendo solos de uma mesma série, parece estranho o fato mencionado mas é necessário esclarecer que, na série Itaguaí, existem vários tipos de solos cujas reações divergem quanto às adubações e, além do mais, que as respostas do amendoim aos fertilizantes não são constantes, variando muito, mesmo em solos do mesmo tipo. Foi constatada, ainda, a negatividade do potássio num dos solos estudados da série Itaguaí, pois este macronutriente neutralizou, quando junto à cal, ao magnésio e ao nitrogênio, a ação benéfica destes, na produtividade. No solo da série Ecologia, somente o efeito do magnésio foi estatisticamente significativo, mas o magnésio, junto ao fósforo e ao potássio, mostrou reação positiva, enquanto que a cal mostrou reação negativa na produção, embora sem significação estatística.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraArruda, Norma Bergallo deBritto, Dirce P.
