THE YIELD AND GRAINS QUALITY OF SOME MAIZE HYBRIDS CREATED AT ARDS TURDA

Maize, due to its superior productions and multiple uses, is one of the main crops. 34 maize hybrids created at the Agricultural Research and Development Station (ARDS) Turda were tested in 3 experimental years (2020-2022). The grain yield and their quality (protein, starch, fats and fibers) were analyzed. The three years were very different from the point of view of favorability, in the first two years optimal conditions were met for achieving a higher production and a better quality of the grains, while in the year 2022 the negative influence is evident both on the production as well as on the quality of the grains. It stands out both for the average productions and for the highest productions in each of the three experimental years the hybrids Turda 344, Turda 3356, Turda 2020 and Turda 380 (12,764 kg/ha average and highest yield in 2021, of 16,280 kg/ha and in 2022, of 9,366 kg/ha). Turda 100 had the highest starch content (76.18%), while for fat and fiber were noted the hybrids Turda 199 (5.22%) and Saturn (3.63%).
