A field study was conducted at the experimental farm of CSIR-Institute of Himalayan Bioresource Technology, Palampur during 2008 and 2009 to assess the effect of different weed control methods viz., chemical, physical and cultural on weed management and growth rate of damask rose (Rosa damascena Mill.) nursery. Atrazine @ 1.0 and 2.0 kg/ha and metribuzin @ 0.75 and 1.50 kg/ha were applied as pre emergence in combination with one hand weeding at 4 months after planting. Both the herbicides were effective in reducing the weed population and biomass. Black polythene mulch was quite effective in controlling weeds, improving establishment and growth of nursery plants. Higher weed control efficiency (97.6%) next to weed free treatment was recorded in black polythene mulch as compared to other treatments. Use of black polythene mulch provided higher value of in- creased yield ( 19.2 105/ha) while net income was higher due to application of atrazine @1.0 kg/ha+ 1 H.W. ( 22.1 105/ha).References
