| It was aimed to evaluate the efficiency of spreading drops in cassava leaves of Solutions with Biological insecticides and adjuvants in different concentrations. The experimental design was completely randomized in a factorial 2 x 3 x 5, with four replications. The treatments consisted in the preparation of solutions of two biological insecticide Bacillus thuringiensis (500 g ha- 1, Dipel WP® - 32,0 g kg-1) and baculovirus (0,41 g ha- 1) , with addition of three adjuvants (Mineral oil-Nimbus®, vegetable oil- Aureo® and glycerine- Hygrogem® , soybean biodiesel byproduct ) in five concentrations (0,0; 0,2; 0,4; 0,6 and 0,8 % v v- 1), cassava leaves comes the variety 'IAC 90'. The spreading of the drops (13μL) of the solutions were evaluated in adaxial and... |

| This study aimed to evaluate the spatial and temporal variability of chemical attributes of a Red Oxisoil due to the application of lime and potassium chloride in variable rate through the use of thematic maps. The study was conducted in the municipality of Terra Roxa, Paraná State, Brazil, in farm of 41.68 hectares, in which two samples were taken, the first held in 2010, prior to the application of the products, and the second in 2013. In each sampling chemical attributes were measured: pH in CaCl2 0.01 mol L-1, potassium (K), base saturation (V%) and the participation of K in the exchange complex (%K). For realization of geo-referenced mapping, the property was divided into grids of three acres, by collecting soil samples in the depth 0-20 cm. From... |
