بررسی مدیریت تلفیقی علف‌های هرز (مکانیکی - شیمیایی) در مزارع ماش(Vigna radiata L.)

The mung bean plant (Vigna radiata L.) is one of the summer legumes in the northern region of Khuzestan, and its cultivated area is about 7000 hectares. One of the problems of increasing the area under culture and the yield of this crop is the presence of weeds that compete with crops for environmental resources. Based on this, research on the control of weeds in mung bean fields seems necessary. This study was carried out in 2020-2021 As a strip plot with 18 treatments in four repetitions based on the statistical design of randomized complete blocks in Safi Abad Agriculture and Natural Resources Research and Training Center fields.Vertical factor, Cultivator application in three levels including: 1- Shovel cultivator. 2- Blade cultivator. 3- No cultivator. horizontal factor, herbicides in six levels including: 1-Trifluralin 2 lit/ha soil incorporated. 2- Post-emergence application of Oxyfluorfen EC24% herbicide at the rate of 1.5 lit/ha at the beginning of weeds growth. 3- Post-emergence application of imazathapyr SL10% herbicide at the rate of 400 ml/ha + Cytogit oil 200 ml/ha at the beginning of weeds growth. 4- Post-emergence application of imazathapyr herbicide at the rate of 1 lit/ha at the beginning of weeds growth. 5-pre-emergence application of pendimethalin EC33% herbicide at the rate of 4 lit/ha. 5-weed free check. Analysis of variance showed that there was a significant difference between cultivation treatments and herbicide treatments in weeds control and mung bean yield. The results of the research showed that between the different cultivator treatments, the shovel cultivator produced 2.281 ton/ha had the highest yield of mung bean seed and between different herbicide treatments, the use of pendimethalin herbicide 4 lit/ha in pre-emergence, with 93% control of weed density, 89.2% control of weed biomass and 2.409 ton/ha mung bean yield was superior. The combination of these two mechanical and chemical treatments is recommended for the integrated management of weeds in mung bean fields in Khuzestan province.
