BEHAVIOR OF LOCAL AND FOREIGN WINTER WHEAT VARIETIES AT DIFFERENT SOWING DENSITIES IN THE SOUTHERN PART OF THE COUNTRY

Abstract

in Romania, climate change has determined in recent years, the intensification of water deficits (often associated with scorching heat) during the vegetation of agricultural crops, in almost all areas of the country. The cultivation of winter wheat varieties that can withstand drought and heat well and the adaptation of cultivation technology to climate change are decisive factors in obtaining stable and economically efficient yields. In the agricultural years 2018/2019 - 2019/2020, at ARDS Teleorman, a multifactorial experiment of type 3 x 3 x 2 was set up, which aimed to determine an optimal density depending on the varieties used and climatic conditions. The experiment was placed according to the method of plots subdivided into 3 repetitions, with the following factors: Factor A variety, with 3 graduations (a₁ = Glosa; a₂ = Avenue; a₃ = Rubisko); Factor B density, with 3 graduations (b₁ = 400 g.g./m²; b₂ = 650 g.g./m²; b₃ = 750 g.g./m²); Factor C year, with 2 graduations (c₁ = 2018-2019; c₂ = 2019-2020). The highest yield was obtained by the variety Rubisko (9,282 kg/ha), compared to the average of the tested varieties. On average, the highest yields were obtained at a density of 650 g.g./m² (9,266 kg/ha).
