Dubey, R.K.Komaldeep Kaur2019-08-302019-08-302019http://krishikosh.egranth.ac.in/handle/1/5810124943A research trial entitled “Weed management in rose through integration of straw mulch and oxyfluorfen” was enacted at the Research Farm, Punjab Agricultural University, Ludhiana to study the influence of integration of straw mulch and oxyfluorfen on weeds, on growth as well as flowering parameters of rose. The experiment was spread out in Randomized Complete Block Design (RCBD) with seven treatments that consists of Paddy straw mulch @0.6kg/m2, Paddy straw mulch @1.2 kg/m2, Oxyfluorfen @0.025g/m2, Oxyfluorfen @0.025g/m2 + Paddy straw mulch @0.6kg/m2, Oxyfluorfen @0.025g/m2 + Paddy straw mulch @1.2kg/m2, Hand weeding (at monthly interval) and unweeded control. The weed species Amaranthus viridis, Anagallis arvensis, Chenopodium album, Euphorbia hirta, Oxalis martiana, Phyllanthus niruri as broadleaves, Dactyloctenium aegyptium, Digitaria sanguinalis and Eleusine indica as grasses and Cyperus rotundus as sedge were observed in the field. The findings unfold that integration of straw mulch and oxyfluorfen decreased the weed density of all aforesaid weed species and biomass of dry weeds of sedges, grasses, and broadleaves weeds, rather than the application of paddy straw mulch and herbicide alone. Further, the effect of Oxyfluorfen @0.025g/m2 + Paddy straw mulch @1.2kg/m2 was more pronounced than Oxyfluorfen @ 0.025g/m2 + Paddy straw mulch @0.6kg/m2. The expansion in the growth parameters attributing to plant height, plant spread and a number of branches as well as a rise in the number of flowers, flower yield, flowering duration, and flower diameter was observed with oxyfluorfen @0.025g/m2 + Paddy straw mulch @1.2kg/m2. Apart from that, minimal days to flowering and the highest net returns were also turned out in the same. However, all these parameters were recorded superior in hand weeding but expensive. The mulching results in increase in soil temperature during cold periods and drop in the same with rise in temperature. Along these lines, for realizing better management of weeds and higher production, the combination of oxyfluorfen @0.025g/m2 with Paddy straw mulch @1.2 kg/m2 could be taken over in rose.ennullThesis
