Abstract

The research was carried out in the western part of Romania, in Belin?, a commune located in the N-E area of Timi? County. The climate is temperate continental, with an average annual temperature of 10.6В°C, the heat regime being favourable to the sweet corn crop. The average annual rainfall value of 605.5 mm provides relatively good conditions for the crop under study. The type of soil is a Eutric alluvial soil, fine-grained sandy-loam/medium sandy-loam, on rough fluvial materials, with a pH of 5.80 in water, and humus content 1.61%. The experiments were bi-factorial, where factor A was the cultivated hybrid (Prima - very early; Summer Delight - semi- early and Diamond - semi-late). Factor B - the agri-fund with 5 graduations (N0P80K80; N100P80K80;N150P80K80; N150P80K80+ 2t/ha of dolomite and N150P80K80+ 4t/ha). The synthesis of the harvest results shows that, on average on the fertilization levels, the lowest harvest of corn cobs was with the Summer Delight hybrid (12959 kg/ha), and the yields on Prima hybrid (13633 kg/ha) and Diamond hybrid (13767 kg/ha) were similar. The nitrogen fertilisers applied on a constant background of P80K80 increased the harvest compared to the control variant by 21% in the variant with N100, by 33% in the variant with N150, by 43% in the variant with N150+2 t/ha of dolomite and by 51% in the variant with N150+4 t/ha of dolomite. The results of the chemical analysis of grains harvested in the maturity phase in milk related to the humidity content of grains, the content of carbohydrates, protein and fat substances is rendered in the paper.
