RESEARCH ON WINTER RAPESEED CROP USING DIFFERENT GROWING TECHNOLOGIES

Abstract

Recently, more and more environmentally friendly tillage systems have been becoming more widespread, one of which is strip tillage and seeding. That is why a field experiment was conducted at the VDU Agricultural Academy Training Farm in 2023–2024. The winter rapeseed variety 'Desperado' was chosen for the study. Two tillage technologies were compared in a field experiment: 1. Conventional - plowing; 2. Strip tillage. The study assessed the impact of different rapeseed growing technologies on soil temperature and moisture after the resumption of winter rapeseed vegetation in spring, soil respiration - biological activity during the rapeseed vegetation period, and soil agrochemical properties before harvest. The study found that soil temperature in winter rapeseed crops was higher in most cases when conventional tillage technology was used. The temperature in the strip tillage fields was uneven, i.e. in the rows of plants it was like that in the ploughed soil, and in the interrow, where most of the plant residues were distributed, it was lower. Different soil preparation and sowing methods affected moisture distribution and microbial activity. Different cultivation technologies did not significantly affect the agrochemical properties of the soil after winter rapeseed harvest, except for total nitrogen. A significantly larger (37,2 %) total nitrogen content was found in fields using conventional - arable technology.
