Studies on Chemical Control of Weeds in Broadbean (Vici a faba L.)

Abstract

An investigation was made on the effect of the herbicides Balan and Treflan on weed control, nodulation, growth and yield of broadbean. Balan at 1 and 2 kg/ha significantly reduced weed density by more than 50% and increased seeds and straw of broadbean from 24 to 75%. It had no harmful effect on nodules formation.
Treflan at 0.5 kg/ha decreased weed population by 40% and increased seed and straw of bean by about 30%, whereas, Treflan at 1 kg/ha significantly reduced weeds by 65% but this was associated with significant reduction in seed and straw of bean by 28 and 41%, respectively. It also decreased nodulation.
