RESEARCH REGARDING THE INFLUENCE OF THE FERTILIZATION SYSTEM ON MAIZE PRODUCTION IN BRAILA PLAIN

Due to the fact that the fertilization system of the maize plant is directly involved in the growth and development processes, they influence both the fertility of the soil and the yields obtained. The main objective for the research conducted in the crop year 2008-2009 was to determine what is the effect of chemical fertilization in the climatic conditions of this specific year, particular to the Ramnicelu area from Braila Plain, on PR36R10 and Florencia maize hybrids. The polyfactorial experiment was made here in order to investigate and estimate the influence of the fertilization factor on the crops that were obtained, analyzing the differences between the productions obtained in the crop year 2009 and 2010. The average yield obtained was directly influenced by climatic conditions, rain and by the amount of fertilizer used. In 2009, the average yield produced for the Florencia hybrid varied from 5800 kg/ha for the unfertilized version, to 9280 kg/ha for the fertilized ones while the production for the PR36R10 hybrid registered a growth of 2130 kg/ha for the version placed on an agrofond of N-100 P-50.
