This paper presents the results of a study conducted at ARDS Marculesti in 2017 and 2018 on the influence of 5 new maize hybrids under different irrigation conditions on the size features of the maize cobs, namely the number of rows per cob and the number of grains per row. The experiment was set up using the two-factor subdivided plot method, the A-factor was the maize hybrid and B factor-irrigation regime. The subdivisions of A factor: a1- P9175 (FAO 330), a2 - KWS BELLAVISTA (FAO 330), a3 - KWS SMARAGD (FAO 350), a4 - KWS KASHMIR (FAO 370) and a5 - KWS DURANGO (FAO 480). The subdivisions of B factor: b1 – unirrigated; b2 – stressed at and after flowering; b3 – stressed before flowering and b4 – full irrigated throughout the vegetation period. Regarding the number of rows on the cob, the best results were obtained by the hybrids KWS Bellavista and KWS Smaragd and the lowest, by the hybrid P9175.
