Research of the Influence of Agrophytotehnical Works on Rapeseed Production Parameters

Abstract

Two tillage systems were studied between 2022 and 2023 in Grebenișu de Câmpie and near Ungheni city (Mureș County, Romania) and their impact at growth and production parameters of rapeseed crop. Also, for each tillage system, the growth plant parameters have been monitorized. One of the studied tillage systems was conventional, including stubble cultivation followed by ploughing at 25 cm depth. The second tillage system was minimum tillage, using a trailed field cultivator for soil preparation, at a depth of 20-25 cm, one day before seeding. In both tillage systems, power harrow was used before seeding. During the growth stages of rapeseed, the plants were analyzed and compared for each tillage system and for each field from Ungheni area and from Grebenișu de Câmpie. The morphological characters were analyzed in laboratory. All colected data were statistycal represented in tables by location and by tillage system. In the variant with conventional plough, average height, number of branches, stem thickness and root development were smaller than in the fileds with minimum tillage. Regarding the morphological characters of plants, a significant difference was determined in the height and the number of plant branches, the values were higher at minimum tillage system.
