The objective of this work was to evaluate the grass cover crop production in crop systems involving maize and Urochloa ruziziensis, and the influence of topdressing nitrogen rates in the yield and agronomic efficiency on common-bean cultivated in succession in no-tillage. The experiments were conducted in Jaboticabal-SP, in a eutrophic red latosol, in the second year of no-tillage system implementation. The IPR 139 cultivar was used in split plot design with three replications, in randomized block. The plots had been composed for three crop systems in the summer season, with maize exclusive, maize intercropped with U. ruziziensis and U. ruziziensis exclusive. The subplots had been constituted for five nitrogen rates (0, 40, 80, 120 and 160 kg ha(-1)), applied as topdressing at V4-4 in irrigated common-bean cultivated in the winter-spring season. The use of U. ruziziensis in crops systems, exclusive or intercropped with maize favors the grass cover crop production sufficiently to total soli surface covered, possibility similar grain yield compared to maize exclusive. The topdressing nitrogen application doesn't affect the common-bean yield in succession to maize and U. ruziziensis intercropped. The increase of nitrogen rates in common-bean in succession to maize exclusive improves the yield, although decreases the agronomic efficiency.

The main purpose of this article is to relate two among the most important themes of the current organizational dynamic: organizational culture, innovation and environmental management. Great part of the literature about environmental management and environmental innovation refers to organizational culture as the most arduous wall or the most significant element to develop effective practices of business environmental management. However, relationship among such concepts is, many times, superficial or camouflaging the necessary analytic depth. To solve this challenge, this article integrates the levels of the organizational culture (workmanships, values and presupposed unconscious), the typologies of environmental innovation (total productivity of resources, innovations for the segregation of materials and articulation of bio-systems), and the environmental technologies (end-of-pipe, environmental measurement, pollution prevention and zero-impact technology). Recommendations and challenges for the continuity of this research are registered.
