| In order to explain the variation of each component of the Gross Value of Production (GVP) it is necessary to decompose the grouped value. Shift-share is a method used in studies of changes in the regional economy that allows the segmentation of the factors that affect the GVP of certain product. The objective of this study was to analyze the influence of the variables harvested area, yield and price in the rate of percentage variation of the GVP of the cassava (Manihot esculenta) production, in the main producers counties, in Alagoas state, for four periods of six years (1990-1996, 1996-2002, 2002-2008 and 2008-2013) and also for the entire period (1990-2013). Results indicated that the variables price and productivity had positive effects, while... |

| This study aimed to assess the impact of ethrel spraying on cassava leaf abscission at different stages of cultivar development. Two experiments were performed using randomized block designs, with 15 total treatments (three repetitions of five conditions) arranged according to the factorial scheme 3 x 5. Experiment 1 (ethrel application in the vegetative development period) consisted of three seasons (November 2013 and 2014, January and February 2014) and four concentrations of ethrel (1,500, 3,000, 4,500, and 6,000 ppm) and a control (no application); Experiment 2 (application in pre-harvest period) consisted of three periods of ethrel spraying (20, 40, and 60 days before harvest), four ethrel concentrations (1,500, 3,000, 4,500, and 6,000 ppm) and a... |
