The paper presents the results obtained at NARDI Fundulea, Rice Experimental Center Chirnogi during 2003-2005. To establish the sowing density, a bifactorial experiment 6 x 7 type was performed. Six sowing densities, with values between 500 germinable grains/m2 and 100 g.g./m2 and an ecart of 200 g.g./m2 were tested. Besides density, seven genotypes were studied, as follows: Polizesti 28, Elida, Dunarea, Zefir, Magic, F40 and F42. The results show the superiority of 700 g.g./m2 density for the genotypes F40 and Magic and of 800 g.g./m2 for the other genotypes
