The researches presented in this paper were carried out during agricultural year 2019 in Grădiștea, Ilfov County and the main objective was investigation of the variability of yield for maize hybrid P0268 under application of a starter microgranular fertilizer with a 25 kg∙ha-1dose. The chosen hybrid is characterized by high yield, resistance to drought and high temperatures, being suitable for all types of soils, including those with low level of organic matter. The selected microgranular fertilizer for experiment ensures fast start of crops, accelerating the germination and influence positively the development of root system. The efficiency of microgranular fertilizer was evidenced at all maize vegetation stages and consisted in more vigorous and intense green colored plants, well developed radicular system and stems in comparison with unfertilized control variant. At harvest time, the grain yield in the case of fertilized variant was with 229 kg∙ha-1, higher in comparison with control. This experiment reveals the efficacy of microgranular fertilizer application on maize yield, but under climatic conditions of the agricultural year 2019, economic efficiency was low.
