Abstract

The research was made in the hilly area of Southwest Romania, on the territory of Caras Severin County. The researched area has a moderate continental temperate climate. According to Koppen, the climate is classified as c.f.b.x. The annual average temperature is 10.8В°C and the annual average precipitation is 631 mm. The soil type on which the research was made is typical gleisoil with a pH value in water of 6.02 and a humus content of 2.56% [5]. The dolomite used in the research was chemically analyzed in Austria, at the Institute fur Nachhaltige Flanzenproduktion (Institute for Sustainable Plant Development) of Wien. The analysis bulletin showed that the analyzed calcium and magnesium mineral contained CaO 32.8%, CacO3 58.5%, MgO 19.6%, MaCO3 40.9%. The bulletin also contains data related to copper (Cu), zinc (Zn), lead (Pb), cadmium (Cd), chrome (Cr), nickel (Ni), mercury (Hg), in smaller quantities than the global permissible limits. The research focused on the effect of the dolomite applied in quantities of 2 t/ha and 4 t/ha on five levels of fertilizers with nitrogen applied on a constant basis of P100K100. The resulted harvest increase, on average on the experimented NPK doses, due to dolomite were 17% at the dosage of 2 t/ha and 28% for the 4 t/ha. The mass of 1000 kernels on average on the NPK doses increased from 345 g without dolomite to 352 g for dolomite 2 t/ha and to 358 for dolomite 4 t/ha. The content of raw protein increased by applying dolomite from 9.96% in the control sample to 10.40% on the basis with 2 t/ha and to 12.01% on the basis with 4 t/ha. The paperwork also contains the results of the analyses related to the evolution of the starch and fat content. The increase of nitrogen have a decreasing influence on starch quantity and the amount of dolomite have no effect over the decreasing trend of starch related to nitrogen amount.
