CRESCIMENTO E PRODUÇÃO DO FEIJOEIRO COMUM COM USO DE SILICATO DE CÁLCIO E MAGNÉSIO EM SOLO DO CERRADO

Abstract

The Cerrado soils have limiting points for production, such as sandy textures, acidic pH and low fertility, so it is essential to use liming and fertilization. The objective of this work was to evaluate the growth and production of common bean, BRS FC-104 (commercial group from Rio de Janeiro), using calcium and magnesium silicate as a soil amendment. The test was carried out in a greenhouse at the Escola Fazenda do Instituto Federal Goiano - Campus Posse, Goiás. The design used was completely randomized, with three treatments and eight replications (T1 soil correction with calcium and magnesium silicate); (T2 soil correction with dolomitic limestone); (T3 control treatment, without use of correction). Plant growth and productive aspects of common bean were evaluated. Based on the analysis of plant growth and productivity variables, it was possible to observe that the use of calcium and magnesium silicate as a soil corrective was efficient in aspects of bean productivity, however the growth and development of the culture was inferior in relation to to the use of dolomitic limestone.
