Abstract:
The study titled "To workout the economics of chickpea (Cicer arietinum L.) under effect of different herbicides" was conducted at the Research Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during the 2020-21 rabi season. The experimental field featured neutral soil pH, characterized by low nitrogen, medium phosphorus, and high potassium levels. The research followed a randomized block design with three replications, incorporating a total of 15 distinct herbicidal treatments.viz. (Treatment 1 - Oxadiargyl 80 gram per hectare 0-3 Days After Sowing), (Treatment 2 _- Metribuzin 350 gram per hectare 0-3 Days After Sowing), (Treatment 3 _- Topramezone 19.35 gram per hectare 2-3 Leaf stage of weed), (Treatment 4 _-Topramezone 25.8 gram per hectare 2-3 Leaf stage of weed), (Treatment 5 _- Topramezone 32.25 gram per hectare 2-3 Leaf stage of weed), (Treatment 6 _- Topramezone 25.8 gram per hectare 5-6 Leaf stage of weed), (Treatment 7_- Topramezone 32.25 gram per hectare 5-6 Leaf stage of weed), (Treatment 8 _- Metribuzin followed by Topramezone 350-25.8 gram per hectare 0-3 Days After Sowing and 2-3 Leaf stage of weed), (Treatment 9 _- Metribuzin followed by Topramezone 350-25.8 gram per hectare 0-3 Days After Sowing and 5-6 Leaf stage of weed), (Treatment 10 _- Fluzifop-p-butyl 13.4 percent + Fomesafen 11.1 percent 250 gram per hectare 5-6 Leaf stage of weed), (Treatment 11 _- Sodium acifluorfen 16.5 percent + coldinafop-proparzyl 8 percent (directed application) 187.5 gram per hectare 2 to 3 leaf stage of weed), (Treatment 12 _- Mertibuzin (directed application) 350 gram per hectare 2 to 3 leaf stage of weed), (Treatment 13 _- Metsulfuron (directed application) 4 gram per hectare 2 to 3 leaf stage of weed), (Treatment 14 _- Hand weeding twice 20 and 40 Days After Sowing) and (Treatment 15 _- Unweeded control). On November 15, 2020, the chickpea variety 'Indira Chana 1' was sown, utilizing a seed rate of 80 kg per hectare and spaced at 30 cm intervals, and the crop was successfully harvested on March 5, 2021.
