The Influence of the Fertilization System and of Soil and Climate Conditions on Maize Yield

Starting from frequently encountered situations regarding the restrained structure of cultivated plants and simple crop rotations in different agricultural exploitations in the Banat Plains, we tested the influence of mineral fertilisation on maize culture with the purpose of enhancing biomass yield both total and useful in that culture. The effect of fertilisers was tracked both from the standpoint of the unilateral influence of nitrous, phosphorus and potassium fertilisers as well as complex, correlated with the soil and climate conditions. Yield increases were between 185,0 kg/ha (P50K50) and 7420,75 kg/ha (N200P150K150) compared to the control variant and the level of intensifying of the yield process through fertilisation can be established for each agricultural exploitation compared to the technical-economical conditions and the agricultural system used.
