Abstract: The Climatic condition for Rose is favourable in Jharkhand. Winter is the main season for this crop. It has been that seen during December to mid-January the minimum temperature goes below 7^0C which effect the Production. On the other hand, due to acidic and sandy loam soil, weeds are one of the serious problem in this region which reduce the yield of about 30-45% (Singh and Singh, 2004), it also affects its yield and deteriorate the quantity and quality of flowers. To overcome these problems, one experiment has been planned to see the effect of mulching on rose cv. Maine Parle was conducted during October-March, 2015-16 at B.A.U, Ranchi. On the basis of observations, The weed count/m² and dry weight of weeds were significantly minimum in Black Polythene, 200 micron (5.66/m² and 1.93g/m²) respectively as well as duration of flowering and flower diameter (12.33 cm) was also found maximum in Black Polythene (200 micron) whereas maximum count and dry weight was found in White Polythene 50 micron (451.27 g/m² and 325 g/m²) respectively. Among the reproductive characters, the maximum number of shoots (11.47), number of flowers (47.00 flowers/plant) (Singh and Kamal, 2012) was found in black polythene 200 micron whereas minimum was observed in weedy control (15.60).
