“…These results corroborate with the literature, such as by Nicoloso et al (2006) and Trogello et al (2012), who report differences in 1300 and 2000 kg Table 1. Average remaining dry forage mass (RDFM) and grain productivity (GP) grown in no-tillage system in integrated crop-livestock system, in five agricultural years and in different heights of forage mass post-grazing.…”

Forage management in integrated crop-livestock system is a complex activity that increases profitability, when well performed, therefore consequently influencing future crop productivity. This study aimed to evaluate the agronomic performance of corn cultivation in the integrated crop-livestock system using the no-tillage system in different forage masses post-grazing. . In absolute terms, the winter pasture management of 0.2 m high presented the best results in terms of corn grain productivity.

“…This result is justified by the greater soil depth capacity of the shank-type opener, thus providing greater planting depth. Similar results were obtained by Trogello et al (2012) and Modolo et al (2013) who worked in TypicHapludox compacted by a crop-livestock integration system. However, some authors obtained opposite results due to the more stable furrow walls provided by the double disc opener (Reis et al, 2004).…”

The heavy traffic of machinery and implements in no-tillage areas leads to surface compaction, especially when the managed soil contains high levels of moisture. This problem is one of the main causes of increased power demand in seeding operations. The aim of this paper was to assess the performance of two furrow opener mechanisms for planting soybean in clay soil with different levels of compaction and assess their relationship with traction demand. A random blocks experimental design with subdivided plots was used. The plots had four levels of soil compaction (1.16, 1.20, 1.22, and 1.26 Mg m -3 ), and the subplots consisted of furrow openers (double-disc opener and shank-type opener) with four replications. Soybean sowing was carried out with a no-tillage seed with five lines. Seed deposition depth; cross-sectional area of mobilized soil; depth and width of the groove and the power demand measured by a load cell coupled between the tractor and the seeder were analyzed. The shank-type furrow opener increased the depth and width of the furrows, the planting depth and the disturbed area, and required greater power demand as the density of the soil increased. The contrary was observed with the double disc opener as this furrower presents low capability to reach d eeper layers in compacted soil, as a result of its design characteristics.

“…In the same year, a positive effect from nitrogen fertilizer applied on pasture was found in the FEH and SD of corn plants. Trogello et al (2012) found that in an ICL system with black oat pastures managed at heights of 0.05, 0.15, and 0.30 m with herds, the initial plant height, first ear height, and productivity of corn grains were all adversely affected when the grazing height was 0.05 m.…”

ABSTRACT. The objective of this study was to evaluate the agronomic characteristics of corn seed inoculated with Azospirillum brasilense, grown on black oat and ryegrass straw, and managed under different grazing strategies and doses of nitrogen. The experiment was conducted in Santa Maria, Rio Grande do Sul State, Brazil, during two agricultural seasons (2012/2013 and 2013/2014) in a randomized, complete block design with three replications. In the winter period, black oat and ryegrass straw were managed at different grazing heights by sheep (0.30, 0.20, 0.10 m, conventional grazing, and no grazing) with three doses of nitrogen (0, 50, and 100 kg ha The height of corn plants was greater when they were grown on black oat and ryegrass straw, and the absence of grazing favored productivity. Under drought conditions, the application of nitrogen to the pasture favored corn development, increasing plant height, ear height, and stem diameter. Inoculation with A. brasilense had a positive effect on the characteristics of yield and productivity of corn, independent of growing season and hybrid used.
