ABSTRACT

Observations were carried out on the plant composition of apple orchard floors in different soil management methods (herbicide strips under trees vs. herbicide applied to entire orchard floor) in the years 1981-1996 (orchard I) and 1981-1989 (orchard II). Capsella bursa - pastoris (L.) Med., Convolvulus arvensis L. and Erigeron canadensis L. predominated in herbicide strips in the tree rows, Amaranthus retroflexus L., Echinochloa crus - galli (L.) P.B., Erigeron canadensis L., Polygonum aviculare L. and Taraxacum officinale Web. – in alleyways under over-all herbicides, and Agropyron repens ( L.) P.B., Lolium perenne L., Poa annua L. and Taraxacum officinale Web. were the most abundant components of sod in interrows. The changes occurring in consecutive years and possible reasons for variable species behavior are discussed.

Key words: apple orchard, weeds, soil management.
