THE INFLUENCE OF AGRICULTURAL TILLAGE SYSTEMS AND SOWING DEPTH ON THE DEGREE OF WHEAT EMERGENCE

Abstract

Soil preparation for wheat crop establishment has a complex influence on its physical, chemical and biological properties, having a direct impact on agricultural production. The present work aimed to analyze the effect of germination bed preparation methods on wheat sowing operations and, subsequently, on the degree of plant emergence. The studies were carried out in the southwest of Dolj County, in Brabova commune, on the lands of an agricultural holding. The experiment was carried out on a total area of 6 hectares, divided into three distinct plots, each of two hectares. The following germination bed preparation and sowing methods were applied on these plots:Plot 1 (TAV): Conventional works for autumn sowing, on a land covered with corn plant residues, followed by a chopping work.,Plot 2 (LDG): Light tillage with heavy disc harrows on a field covered with rapeseed residues.,Plot 3 (LGR): Tillage with a vertical rotor harrow after the sunflower precursor crop had flowered.Immediately after the preparation work, a series of essential soil characteristics were determined for each plot, including: soil moisture, degree of fragmentation, degree of compaction, optimum moisture depth (moisture line) and uniformity of seed embedment depth. The research will continue throughout the entire vegetation cycle by monitoring the evolution of the crop and will end with the evaluation of the final wheat production obtained.
