FLORISTIC COMPOSITION OF WEEDS AS INFLUENCED BY SOWING TIME AND HERBICIDES IN BERSEEMPushpendra Singh Yadav, M.L. Kewat, A.K. Jha, M.P. Sahu, Badal Verma, and Oscar ToppoAbstract 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. |
