Weed management with herbicdes in chickpea

“…In general, maximum density and dry weight of weeds were observed with 5 t ⋅ ha -1 FYM (farmyard manure) in comparison to other treatments. Furthermore, the number of pods ⋅ plant -1 and 100 seed weight of chickpea was also found to be insignificant due to fertilizer treatment (Patel et al 2006).…”

Weeds are one of the most important limiting factors in the production of chickpea (Cicer arietinum) in Iran, especially in autumn sown chickpea. Weed density and biomass in autumn chickpea are seven and two and a half times higher than the spring chickpea, respectively. The weed damage to chickpea in Tabriz, Kermanshah and West Azerbaijan was estimated at 48.3, 57 and 36%, respectively. Sixty-four weed species were identified in chickpea fields. Convolvulus arvensis L. and Galium tricornutum Dandy have the highest presence in chickpea fields. Pyridate and linuron are the only herbicides registered for use in chickpea fields in Iran. However, research results show that fomesafen and isoxaflutole are the most appropriate herbicides for chickpea fields. Oxyfluorfen, imazethapyr, metribuzin, trifluralin, simazine, terbutryn and pendimethalin are the major herbicides studied in weed control research. The combination of herbicides and mechanical control is one of the effective methods to reduce weeds. Hand weeding and cultivation between rows are the most effective mechanical methods of weed control. High nitrogen enhances weed dry weight. Safflower and barley residues reduce weed populations and biomass. Barley-chickpea and wheat-chickpea intercropping systems increase chickpea yield together with proper weed control. In future research, more attention should be paid to surfactants to reduce the use of herbicides, rotation crops and integrated weed management in chickpea.

“…Weeds compete with crops for nutrient, water and space and cause reduction in yield. The critical period of weed competition is 20-30 DAS (Patel et al, 2005). Yield reduction due to weeds ranges from 30-98% depending upon the severity of infestation (Sonani et al, 1985).…”

Background: Clusterbean is one of the most important crop of arid and semi-arid region of India. It is mainly grown for vegetable, manure, fodder and seed purpose. Seeds of clusterbean contain galactomann (stored in endosperm) which has industrial uses, thus making it the major cash earner crop. Various biotic and abiotic stresses affects the crop during its growth stages. Among biotic stresses, weeds are the major one affecting the crop growth and yield. Due to initial slow growth of the clusterbean intense crop-weed competition takes place upto 20-30 DAS and if weeds are not managed properly there will be a severe yield reduction. Under Haryana conditions only manual weeding is recommended which is time consuming and expensive hence there is need to exploit other methods of weed control. Therefore, present study was conducted to study the effect of mechanical methods of weed management on growth, yield and economics of clusterbean. Methods: A field experiment was conducted during kharif season 2018 to study the effect of mechanized weed management practices on growth, yield and economics of clusterbean at Regional Research Station, Bawal (Rewari), CCS Haryana Agricultural University, Hisar. Experiment was performed in randomized block design with ten treatments and three replication. Result: It was found that among various weed management practices, two mechanized weeding with power weeder at 20 DAS and 35 DAS under 60 cm row spacing resulted in significantly higher plant height, leaf area index, dry matter accumulation, seed yield and its attributes in comparison to other treatments and it was statistically at par with mechanized weeding at 20 DAS and 35 DAS with tractor drawn cultivator. The weeding with tractor drawn cultivator was found to be most economical with maximum net returns (Rs. 36076 ha-1) and B:C (2.37) in comparison to other treatments followed by weeding with power weeder that fetched net return of Rs. 35868 ha-1 with B:C of 2.25. Therefore, two times interculture with power weeder or tractor drawn cultivator found beneficial and economical for farmers.
