Abstract

Effect of herbicide combinations on growth, yield and yield components of faba bean (Vicia faba L.).

Abstract

Two field experiments were carried out during 1995-97 in Egypt in faba beans (cv. Giza 2). Herbicide treatments were Topogard (terbutryn + terbuthylazine, 1.5 kg/ha), Igran + Stomp (1.0 kg/ha terbutryn + 1.0 litre/ha pendimethalin), Ramrod + Surflan (1.0 kg/ha propachlor + 0.75 litre/ha oryzalin), Afalon S + Fusilade (1.0 kg/ha linuron + monolinuron + 0.5 litre/ha fluazifop-butyl), Afalon + Treflan (0.5 kg/ha linuron + 1.0 litre/ha trifluralin), Frontiere + Treflan (0.5 litre/ha dimethenamid + 1.0 litre/ha trifluralin), Devrinol + Stomp (1.0 kg/ha napropamide + 1.0 litre/ha pendimethalin), and Sencor + Surflan (300 g/ha metribuzin + 0.75 litre/ha oryzalin). Weed-free, hand weeded twice and unweeded plots were also included. Avena fatua was the dominant weed in the first season, and the best weed control was found in weed-free and hand weeded plots, and plots treated with Afalon S + Fusilade and Frontiere + Treflan. Cichorium endivia [endives] and Ammi majus were the dominant weeds in the other season. Plots treated with Afalon S + Fusilade, Sencor + Surflan, and Topogard or weed-free and hand-weeded plots showed the best weed control and increased number of pods and seeds per plant, straw and seed yield per plant as compared to the unweeded control. Devrinol + Stomp was the only treatment which reduced crop yield and yield components.
