STUDY REGARDING ECONOMIC EFFICIENCY OF CHEMICAL AND ORGANIC FERTILIZERS APPLIED ON NATURAL MEADOWS OF AGROSTIS CAPILARIS AT PREAJBA - COUNTY GORJ

Abstract

The grasslands of Subcarpathian area of Oltenia, can give valuable production when applying chemical fertilizers, organic products or combinations between the two. This work was supported by the strategic grant POSDRU/159/1.5/S/133255, Project ID 133255 (2014), cofinanced by the European Social Fund within the Sectorial Operational Program Human Resources Development 2007-2013.
To determine the economic efficiency of natural grasslands, research has been undertaken within Fodder Crops and Pasture Research Center at Preajba - Gorj, belonging to the University of Craiova, where the grassland was fertilized with chemical fertilizers and organic, using 8variants in 3 rehearsals.
It was determined a set of indicators of economic efficiency: raw product, variable costs, fixed costs, production costs, and the indices: total expenditure rate of profit, income taxes, net profit and net profit rate. Gross profit was calculated using gross profit margin from which were decreased fixed costs, gross profit margin being calculate as the difference between raw product and variable expenses.
