اثر کشت مخلوط افزایشی ارزن بر کنترل علفهای هرز و کارایی استفاده از زمین لوبیا

In order to investigate the effect of intercropping on land equivalent ratio, weed control and yield of millet
and bean an experiment was carried out at the Farm research of Bu-Ali Sina University during 2013.
Randomized complete block design with eight treatments and three replications was used. Treatments
included sole cropping of bean with weed control (T1), sole cropping of bean without weed control (T2),
additive intercropping of 20% millet + 100% bean (T3), 40% millet + 100% bean (T4), 60% millet + 100%
bean (T5), 80% millet + 100% bean (T6), 100% millet + 100% bean (T7) and sole cropping of millet (T8).
Yield of bean and millet and also density and biomass of weeds were affected by treatments. In comparison
with treatment of T2, intercropping decreased significantly weed density and biomass. The highest and the
lowest values of weed density and biomass were revealed at T2 and T7 treatments, respectively. All
intercropping treatments had LER>1 and the highest value of this index belonged to treatment of T7. In
general, additive intercropping of millet with bean suppressed weeds and increased land use efficiency of
bean.
