Abstract

Aims: To evaluate the effect of different weed management options on the economics in groundnut + pigeonpea relay intercropping on medium black clayey soils of Junagadh .

Study Design: Field experiment was conducted at Junagadh during kharif 2019-20 and 2020-21 in Randomized Block Design with three replications to evaluate the effect of different weed management options on the economics in groundnut + pigeonpea relay intercropping on medium black clayey soils. The treatments comprised of: pendimethalin 0.9 kg ha-1 as PE fb interculturing and hand weeding at 45 DAS, pendimethalin 0.45 kg ha-1 + oxyfluorfen 0.09 kg ha-1 as PE fb interculturing and hand weeding at 45 DAS), interculturing and hand weeding at 15 DAS fb sodium acifluorfen 16.5% + clodinafop propargyl 8% (ready mix) 1 kg ha-1 at 45 DAS as POE, interculturing and hand weeding at 15 DAS fb quizalofop p ethyl 40 g ha-1 at 45 DAS as POE,  interculturing and hand weeding at 15 DAS fb propaquizafop 70 g ha-1 at 45 DAS as POE, pendimethalin 0.9 kg ha-1 as PE fb sodium acifluorfen 16.5% + clodinafop propargyl 8% (ready mix) 1 kg ha-1 at 45 DAS as POE, pendimethalin 0.9 kg ha-1 as PE fb quizalofop p ethyl 40 g ha-1 at 45 DAS as POE, pendimethalin 0.9 kg ha-1 as PE fb propaquizafop 70 g ha-1 at 45 DAS as POE (T8), weed free, and unweeded control (T10).

Place and duration of the study: Instructional Farm, Department of Agronomy, College of Agriculture, Junagadh Agricultural University, Junagadh during kharif seasons of 2019-20 and 2020-21.

Methodology: on the basis of prevailing local charges. The gross realization in terms of rupees per hectare. A net return of each treatment was calculated by deducting the total cost of cultivation from the gross returns.

Result: Significantly higher amount of gross returns were recorded with the weed free treatment (T9), which was closely followed by interculturing and hand weeding at 15 DAS fb sodium acifluorfen 16.5% + clodinafop propargyl 8% (ready mix) 1 kg ha-1 at 45 DAS as PoE (T3). Statistically higher net returns and higher net returns and B:C ratio were registered with interculture and hand weeding at 15 DAS fb sodium acifluorfen 16.5% + clodinafop propargyl 8% (ready mix) 1 kg ha-1 at 45 DAS as PoE (T3).

Keywords: Groundnut, pigeonpea, interculturing, pendimethalin, oxyfluorfen, sodium acifluorfen, clodinafop propargyl, quizalofop-p-ethyl and propaquizafop
