In general, tropical soils present low concentrations of zinc (Zn), and the deficiency of Zn is recognized as a world nutritional problem for cereal production and human beings. Therefore, the main goal of this study was to assess the effects of different methods of Zn application on the quality of corn and sorghum grains grown in Oxisol. Two experiments were set up in the experimental area of UNESP (campus of Jaboticabal, Brazil). The following nine treatments were applied:three doses of Zn by banded application (seed furrows), three doses of Zn by incorporation into soil (0-20 cm depth), foliar application, seed application, and control (no Zn applied). The treatments were arranged in randomized blocks with four replicates. The contents of Zn, carbohydrates and proteins were determined for corn and sorghum grains. Regardless of the method, Zn application promoted higher contents of this micronutrient in corn and sorghum grains. The banded application method of Zn in soil promoted greater contents of total carbohydrates, starch and protein in both cultures. The incorporation of Zn into the soil method provided higher contents of soluble carbohydrates in both corn and sorghum grains. |

ABSTRACT: The development of a sustainable agriculture requires the use of agricultural practices that involve a minimum soil tillage. The cropping systems change the dynamics of native arbuscular mycorrhizal fungi and these, on the other hand, determine the contribution of arbuscular mycorrhiza on crop responses to lime and fertilizers and on the efficiency of the cropping system itself. Density of those native fungi in the soil is similar in both till and no-till planting systems and decreases with soil depth, being higher at 0 cm-10 cm. Under no-till system, the external mycelium, developed during the former cropping, is preserved and possibly stimulating the rapid plant root colonization of the following crop. In the first years, grain yield showed to be higher in conventional cropping system with soil tillage. Though, with the increase of the arbuscular mycorrhizal fungi community afterwards, the grain yield increases for both planting systems, and, become similar for the conventional till and no-till planting systems. Under no-tillage cropping system, arbuscular mycorrhizal contribution to plant growth occurs mainly in the 0 cm - 5 cm depth superficial soil layer. |
