Weed infestation of the plantation of sugarsnap peas is one of the main factors contributing to
yield decrease and difficulties in plant harvesting. Therefore the goal of the research was to
specify the influence of the selected ways of weed control on yield and on limiting the
phytocenosis factors of sugarsnap peas field. Strict field research was conducted in years 2009-
2011 in the south eastern region of Poland, at the Research Station in Krasne (50 o 03’N, 22 o 06’E)
of Rzeszów University in Rzeszow. The variables were as follows: (I) varieties of sugarsnap peas
- Sokolik i Milwa and (II) ways of weed control: control without plant protection, mechanical
with harrowing (once after sowing, twice after sprouting), mechanical and chemical (three times
harrowing as above + after sprouting MCPB - 2,0 l/ha, chemical (after sowing chlomazon 0,2
l/ha + linuron - 1,0 l/ha, after sprouting bentazon - 2,0 l/ha), chemical with adjuvant (after
sowing as above, after sprouting bentazon - 1,5 l/ha + adjuvant - 1,5 l/ha). Used methods of
weed control resulted in considerable changes in weed communities of sugarnip peas varieties.
After their application the number of varieties of weeds decreased 10,5–50,1% in comparison
with the control sample, the number of weeds decreased 70,9–87,5% and their air dry weight
decreased 38,9–62,4%. The widest spectrum of weed control, including dominating varieties
Chenopodium album, Viola arvensis, Fallopia convolvulus, on the fields with both Sokolik and Milwa
varieties, were noticed on the fields where chemical and chemical with reduced dose of bentazon
with adjuvant regulations were applied. No considerable differences were notices in yields of
sugarsnap peas between chemical regulation and chemical regulation with adjuvant. The weakest
results as far as yields and weed limitation were concerned were obtained on control fields and
on fields with mechanical harrowing.
