Abstract:
An evaluation of seeding density (60, 120, and 180 kg ha-1) with six durum wheat and two bread
wheat genotypes, was carried out at the Norman E. Borlaug Experimental Station during the fallwinter 2021-2022 crop season. An experimental alpha lattice design was used with three
replications; the plot size consisted of two beds five meters long, separated by 80 cm and with
three rows. Highly significant statistical differences were found between seed densities and
between the genotypes evaluated; the best seed densities (p ? 0.05) were 120 and 180 kg ha-1,
with grain yields of 7,319 and 7,425 kg ha-1, respectively. Genotypes with the highest grain
yield were: STOT (STOT//ALTAR 84/ALD/3/PATKA_7/YAZI_1/4/SOMAT_3/PHAX_1//
