The role of energy-saving methods of basic tillage in the formation of a mass of 1000 grains of spring wheat on leached chernozem of Krasnoyarsk forest- steppe

An important indicator of physical properties of spring wheat grain is the weight of 1000 grains. With the transition to energy-saving technologies of basic tillage the conditions of growth and development of crops are changing. Therefore, in order to study the influence of various methods of basic tillage on the weight of 1000 grains of spring wheat, the studies were conducted on the black soil of Krasnoyarsk forest-steppe. The results of studies conducted in field experiments in EPF"Minino" in 1985-1987, as well as in field experiment of the Department of General Agriculture, laid on educational and experimental farm "Minderlinskoe" in 2016-2018 were presented. The object of the study was leached chernozem, characterized by high humus content (6.1-8.0 %), neutral reaction of soil solution (pH-6.1-7.0) and heavy loam. granulometric composition. The studies were carried out in grain-pasture crop rotation. The scheme of the experiment included options with dump plowing, flat-cut loosening, surface treatment and without the main treatment...
