This study aimed to analyze of using a probiotic (Bacillus subtilis) in the diet of breeding matrinxã (Brycon amazonicus) taking into account the number of oocytes, fertilization rate, hatching and final biomass. The experiment was carried out from March to November 2008. Fifty animals with mean weight 2.35 ± 0.31 kg and mean length 53.00 ± 1.96 cm. Two treatments were used T1 = control group and T2 = 10 g probiotic kg-1 food. The induced breeding was carried out with crude extract of carp pituitary. The result showed that the number of oocytes released, fertilization rate and hatching rates were 5%, 34% and 36% higher than control group. The final total biomass of the control group was 3.6% higher compared to animals treated with probiotic. Concluded that is viable to include Bacillus subtilis in diet of matrinxã for optimizing reproductive indicators.

Proper fertilizing management, in order to optimize fruit quality and yield, is a relevant stage on the production process to the rural entrepreneur profitability. So, the aim of this study was to analyze the economic feasibility of five nutrient management practices for banana crop, Cavendish cultivars, in the Médio Paranapanema region, São Paulo State, Brazil, in 2009/2010. The effective operational cost (EOC) and total operational cost (TOC) structures and three profitability indicators were used. Significant differences were observed among the management systems, and the system that resulted in major economic advantage to the producer provided an average profit rate 25.6% higher than other treatments, with total net revenue about 29.5% higher than other management types. The unitary cost was lower for the most profitable nutrient management practice, although the yieldwas 9.5% lower than the management system that presented the highest yield levels.

The objective of this work was analyze the economic culture of yellow passion fruit (Passiflora edulis) in Marília-SP, the 2010/2011 crop year. Structures of effective operational cost and total operational cost of the culture per area unit were used to the phase of implementation and management of the crop per unit area and five indicators of profitability. Identified a total production cost of US$ 23,743.19 per hectare or US$ 1.19 per pound of fruit. The items of cost effective operating system that most burdened production corresponded to the operations of machinery (31.1%) and labor (23.5%). The profitability indicators proved to be unfavorable to the production system considered in due mainly to the high price of inputs and practices to control diseases. There is need for technical adjustments related to the handling of the crop plant to reduce the total cost of production in order to make the activity profitable.
