||This study focuses on the behavior of some autumn barley genotypes in the temperature, humidity, and soil conditions of the Arad area. The purpose of the study is to find solutions for expanding this crop, considering that this species represents a rich source of starch and proteins with applicability in various economic sectors, like the beer industry or animal fodder. We performed a monofactorial experiment with 5 types of autumn barley (Hordeum vulgare L.), in 4 repetitions, in optimal technological conditions. The experimental variants are V1 – Ametist; V2 – Belissa; V3 – Cardinal; V4 – Laverda; V5 – Lucian. Control lot is represented by the average values of the 5 types taken into study. Abiotic conditions like temperature, precipitations, nebulosity and relative humidity did not register significant differences compared to the multiannual average. The temperature in the sowing period for barley (October – June) was slightly higher than regular values but did not significantly impede the growth and development of plants. Precipitations were overall sufficient to meet the species requirements for the vegetation period, with a small deficit in October, November, and April, and a surplus in June. We evaluated the plantțs size, spike length, grains number per spike, weight of 1000 grains, hectoliter mass, seed production, protein, fat, starch, cellulose, and ash content of grains, and economic efficiency. Genotype-environment interactions generate a high level of variability of cereal plant’s growth and development, especially in the case of barley (Hordeum vulgare L.). Our results show that the barley genotypes taken into study can be successfully cultivated in the Crișurilor Plain in optimal conditions, proving economic efficiency.
