Evaluarea agrotehnică a sistemelor de lucrare a solului la cultura grâului de toamnă

Abstract

The scientific researches were focused on studying the autumn wheat reaction when applying different soil tillage systems. The results of the research have highlighted the priority of the conventional tillage system by plowing and in a conservative way (mini-till), as compared to the conservative system (No-till) has improved of the field weeds’ degree, of water insurance rate, an increase in the productive potential of winter wheat. According the climatic conditions of the agricultural years, the numerical degree of the field weeds was maintained at the „low-very low” level in the conventional and conservative Mini-till system and „low-strong” in the No-till conservative system. During the research years the total and accessible water reserves in the soil layer of 0-100cm, were within the range of „satisfactory-good” to the conventional system and „good-satisfactory” to the conservative tillage. In the conventional soil tillage system, the productivity of winter wheat was 3300-5160 kg/ha, and in the conservative systems respectively 2800-5133kg/ha (Mini-till system) and 1600-3840 kg/ha (No-till system).
