Abstract
The experiment conducted during Rabi season of 2020-2021 and 2021-2022at AICRP on Forage Crops, Department of Agronomy, College of Agriculture, Jabalpur (MP). The soil of the experimental field is sandy clay loam in texture, medium in organic carbon (0.61%), available nitrogen (365.20 kg N/ha) and phosphorus (17.97 kg P2O5/ha) but high in available potassium (308.12 kg K2O/ha). The soil was nearly neutral in reaction (7.24 pH) and concentration of soluble salts (0.35 ds/m) is below to the harmful limit. Twenty treatments comprising of four dates of sowing viz., October 15th, October 30th, November 15th and November 30th as a main plots treatments and these were superimposed with five herbicidal weed control, i.e. Pyroxasulfone 125 g/ha as pre emergence, Pyroxasulfone 125 g/ha at 14 DAS, Oxyfluorfen 100 g/ha + Imazethapyr 15 g/ha after first cutting, Oxyfluorfen 100 g/ha + Imazethapyr 15 g/ha after first and second cutting and control as a sub plot treatments and laid out in a split plot design with three replications. Among the dicot weeds, Medicago truncatula (37.48%), Cichorium intybus (27.74%) were predominant. However, others weeds like Cyprus rotundus (13.79%), Anagallisarvensis (11.21%) Chenopodium album (9.78%) and Cuscuta rflexa (5.59%) were present in Jabalpur.
