Weed interference and control in sugar beet (Beta vulgaris L.)‎

الملخص EN

Two filed experiments were carried out at Tamya Agricultural Research Station, Agricultural Research Center, El-Fayoum Governorate (Middle Egypt) in both successive winter growing seasons of 2016 / 17 and 2017 / 18 to determine the effect of some weed control treatments on yield, yield components, quality of sugar beet (and its associated weeds.

The randomized complete blocks design with four replications was used in these experiments.

The major weed species associated sugar beet crop in field experiments in both seasons were Avena spp., Phalaris spp.

as annual grassy weeds, Brassica nigra L., Chenopodium sp., Sonchus oleraceus L., Medicago polymorpha L., Melilotus indica L., Anagallus arvensis, Ammi majus L., Euphorbia helioscopia and Rumex dentatus L.

as annual broad-leaved weeds.

All weed control treatments statistically significant reduced dry weight of weeds (g / m2 ) in both seasons at 75 and 105 days after planting (DAP).

Hand hoeing three times recorded the lowest value of dry weight of weeds in both seasons.
