IMPORTANCE OF PREDECESSORS IN MODERN CROP ROTATION
Abstract
The paper examines the peculiarities of modern systems of field crop rotations. A review is made of the criteria for selecting the precursors for basic cereals in arable crop rotations in Bulgaria. It reflects the results of years of comparative field trials with different combinations of factors - genotype-fertilization-predecessor. Conclusions are made on the impact of the predecessor on the energy productivity of crops.
Key words: crop rotation, predecessors, crops
