The seedling transplanting ages is a factor of great importance because it can affect the quality and yield of plants if the volume of the cell is not compatible with the phenology of seedlings at time of transplantation. The experiment was conducted at São Manuel Experimental farm, Faculdade de Ciências Agronômicas da UNESP, from March to August, 2009. The objective of this study was to evaluate the effect of seedling age on cabbage production, hybrid Kenzan. The seedlings were grown in polystyrene trays containing 128 cells. Seedings were done every four days and contained the following treatments: 37, 41, 45, 49 and 53 days after sowing (DAS). The experimental design was randomized blocks, with five replications. On transplantation’s day (11/05/2009), the number of leaves, fresh and dry weight and height, were evaluated to the characterization of seedlings. It was observed that the seedling age had no influence on traits at harvest: number of leaves inside and outside of “head”, fresh weight of shoot and “head”, dry mass of shoot and “head” and length of “heart”.

Given the current energy crisis experienced in our country with the lack of rain in some areas, the energy distributors were forced to resort to thermal power plants to complement their energy production; raising the cost of electricity generation, they have been forced to repass this value to the customers through the Tariff Flags. Concerned about a substantial increase in their electric bill, some consumers were forced to look for alternatives so that their results are not affected. The use of diesel generation at peak hours is a relatively simple and inexpensive alternative that has been widely used for several industrial, commercial and service customers. In this present work, we conducted a feasibility study of the use of diesel generators at peak hours in a medium-sized hospital, calculating the depreciation period for the investment through savings in electricity bills
