| The purpose of this experiment was to analyze the effect of five irrigation water depths on oregano production. Oregano is a plant rich in essential oil, commonly used as seasoning in food preparation. The water depths were estimated based on the class A pan evaporation (CPE): 0 CPE (without water replacement); 25 CPE, 50 CPE, 75 CPE, and 100% CPE. The analyzed variables were fresh and dry weight of leaves and roots, yield, net return, and water use efficiency. The experiment was carried out in Presidente Prudente, São Paulo State, Brazil, from February to May 2006. The best results for all the studied variables were found when 100% CPE was used. A linear positive relation was observed between water increments and fresh and dry weight of both the... |

| In order to reduce the impact of decreasing profit margins in crop production systems, all possible options that will increase net profits need to be explored. Land preparation and stool removal in sugarcane production can be a major contributor to overall production costs. Since estimates that mechanization can contribute as much as 50% of the total production costs, considerable savings can potentially be made if the number of tillage operations is reduced. Such savings however, have to be offset against other costs associated with minimum or no-tillage systems, such as the increased need for herbicide. In addition, conventional tillage systems have been implicated in yield decline over the long-term and therefore yield benefits are envisaged, together... |
