Performance in two cultivars of Pennisetum purpureum Schumach at different doses of organic and mineral fertilization

Abstract

The research was carried out in the La Peticera Production Unit, located in El Rosario Sector, San Antonio Parish, Miranda Municipality, Falcón State, in order to evaluate the biomass production of two cultivars of Pennisetum purpureum, Dwarf and CT -115, with organic and mineral fertilization, The experiment was carried out in plots divided into a completely random scheme. The evaluated treatments were: Dwarf / manure 0.5 kg / m2, Dwarf / manure bovine 1.0 kg / m2, Dwarf / manure bovine 1.5 kg / m2, Dwarf / Urea 0,015 kg / m2, CT 115 / bovine manure 0.5 kg / m2, CT 115 / bovine manure1.0 kg / m2, CT 115 / bovine manure 1.5 kg / m2, CT 115 / Urea 0.015 kg / m2 ,The treatments had not significance differences which indicate by organic fertilizing with bovine manure, in the studied P. purpureum cultivars is possible decrease the production costs and the environmental affectations caused by the use of chemical products, without affecting the biomass yielding
