dc.description.abstractThe present study entitled ‘Improvement of propagation technology in Populus deltoides Bart. under nursery condition’ was carried out at the Experimental area of Department of Forestry and Natural Resources, Punjab Agricultural University, Ludhiana during the year 2016-17. The study was conducted to know the suitable time of transplanting, polythene bag size and cutting size and to evaluate the growth parameters of plants under nursery conditions. Two cutting sizes i.e. large 15cm and small 10cm and two polythene bag sizes i.e. large 12cm x 7cm and small 8cm x 4cm were used in the present investigation. First transplanting was done in the first week of May and second transplanting in the first week of June. The observations were recorded for survival per cent and various growth parameters of populus deltoides under nursery conditions i.e. plant height, collar diameter, root length, root spread, shoot fresh and dry biomass. The survival per cent was more in the treatment T1 (May transplant + Large polythene bags + Large sized cutting) as compare to the other treatment combinations. Size of polythene bags influenced the growth of plants. It was noticed from the data that cuttings which were raised in large polythene bags (12cm x 7cm) showed better growth as compared to the cuttings raised in small polythene bags (8cm x 4cm). Cutting length and time of transplanting also had a pronounced significant effect on the growth parameters. The large size cuttings (15cm) raised in large polythene bags (12cm x 7cm) and transplanted in the month of May was found to best in comparison to all other treatment in the study. In general, the growth of plant was better in control except survival per cent.en_US
