The paper presents the results of a research conducted during 2014-2016 with the purpose of identifying the optimal interaction of technological factors for the cultivation of grain sorghum (sowing distance x fertilization level), in order to optimize the yield of crops grown in South-East Romania. The research was carried on a soil chromic luvisol using ten fertilization levels and two sowing distances between rows. Results show that both sowing distance and fertilization had a statistically significant influence on sorghum’s grain yield. The most favourable combination of technological factors, which ensured a maximum yield of 9.22 t/ha, was represented by sowing sorghum at the distance of 70 cm between rows and using a fertilization level N120 P60 K60. Compared to the sowing distance of 50 cm between rows, the sowing distance of 70 cm between rows generated yield increases between 0.21 t/ha and 0.48 t/ha.
