The aim was to evaluate the productive quality and fermentative as like the nutritional parameters of winter grass silage in the vegetative and reproductive stages in two consecutive crop years. The experiment was carried out at Universidade Tecnológica Federal do Paraná, Campus Dois Vizinhos, Brazil, from April 2012 to December 2013. The experimental field had a 560 m2 area; it comprised 32 plots of 16 m2 each...

The objective of this study was to evaluate the production and chemical composition of silages of grass Tanzania and corn, grown single or intercropping. The experiment was conducted at UTFPR Câmpus Dois Vizinhos in the period between October 2011 and July 2012, a 600 m² area. The treatments were: TMI - single corn, TMT - corn and grass Tanzania consortium at the time of sowing, TT - Tanzania grass single, TT32...
Application of CO2 through water reduces the soil solution pH, causing variations in nutrient mobility and consequent effects on the absorption. The objective of this study was to analyze the effects of carbon dioxide rates supplied by drip irrigation in the production of Capsicum frutescens L. crop. A randomized block design with four treatments and eight replications was used. The treatments were four rates o...
