| Abstract The ‘Niágara Rosada’ grape (Vitis labrusca) is the main table cultivar produced in the North and Northwest Regions of the Rio de Janeiro State. This cultivar presents greater rusticity and lower production cost than the cultivars of fine grape (Vitis vinifera L.) because it is more resistant to diseases and the absence of some cultural treatments. The research aimed to determine the economic affordability of the production of ‘Niágara Rosada’ grapes in the north and northwest regions of Rio de Janeiro state, by calculating the Net Present Value (NPV) and the Internal Rate of Return (IRR), and to identify the risk of viticulture, through the sensitivity analysis and the use of the Monte Carlo method. To collect the data, questionnaires, and... |

| Butia capitata (Mart.) Becc., commonly known as jelly palm, is a palm tree native to the Cerrado biome. It is considered an endangered species owing to intensive extractive exploitation of its fruits, with slow and uneven seminiferous propagation as an aggravating factor. Thereby, there are some bottlenecks related to jelly palm seedling production that needs to be optimized. Light quality and intensity is very important to seedling production, as it controls the metabolism of plants and consequently their growth and development. Thus, the aim of this work is to evaluate the effect of shade nets on the growth and physiological aspects of jelly palm seedlings. The experimental design was completely randomized, with five treatments, ten replicates and eight... |
