| dc.description.abstract | The study was carried out in the Faculty of Forestry, Sher-e –Kashmir University of Agricultural Sciences and Technology of Kashmir, Shalimar campus during the year 2011. In modern forestry, it is important to produce quality seedlings as it is considered as the key element for the success of any afforestation programme. So, production of high quality seedlings for large scale plantation programmes needs a readily available and suitable growing medium besides other suitable conditions. Nowadays, the introduction of containers/root trainers has made a tremendous impact on forest nursery seedling production. The root trainer technology offers production of large number of healthy and uniform size planting stock besides improving the quality of seedling. However, this technology has not been standardized for most of the species especially in Kashmir which needs optimization and standardization depending on seedling crop, local climatic conditions and planting technique to be followed. Hence the problem entitled “Influence of growing media and container size for raising quality nursery stock of Tree of Heaven (Ailanthus altissima Mill.)” was undertaken to screen out the best growing media and container size for raising this species. To achieve the objectives seven combinations of growing media i.e. M1 (Soil : Sand : FYM, 1 : 0 : 0), M2 (Soil : Sand : FYM, 1 : 1 : 0), M3 (Soil : Sand : FYM, 1 : 1 : 1), M4 (Soil : Sand : FYM, 2 : 1 : 1), M5 (Soil : Sand : FYM, 2 : 2 : 1), M6 (Soil : Sand : FYM, 0 : 1 : 0), M7 (Soil : Sand : FYM, 1 : 2 : 1) and three different container/root trainer sizes i.e. (C1) 150 cc, (C2) 250 cc and (C3) 300cc were used. The experiment was laid in Completely Randomized Design (Factorial) taking 3 replications. Seeds were sown in containers/ root trainers containing different growing media combinations. The study was carried out for 8 months in nursery from February 2011 to October 2011. Chemical analysis of growing media was carried out before the laying out of experiment for better understanding of nutrient status (available nitrogen, phosphorus, potassium), pH, electrical conductivity and organic carbon. To screen the best growing media and container/root trainer size the Ailanthus altissima Mill. seedlings were assessed for germination, growth, biomass, relative growth rate, plant per cent and quality parameters. The results revealed that the effect of growing media was significant in respect of germination percentage, growth, biomass, relative growth rate, plant per cent and quality parameters of Ailanthus altissima Mill. seedlings. Growing media M¬4 (Soil: Sand: FYM, 2:1:1) performed best in all the parameters i.e. germination percentage (88.18), seedling height (10.88 cm), collar diameter (1.13 mm), fresh shoot weight (1.07 g), fresh root weight (0.71 g), total seedling fresh weight (1.93 g), dry shoot weight (0.54 g), dry root weight (0.55 g), total seedling dry weight (0.90 g), relative growth rate (RGR) (18.11 mg g-1 d-1), plant per cent (69.83), root : shoot ratio (1.01), Dickson’s quality index (0.080). Container/root trainer size also exercised a significant influence on all the parameters. Container size (C3) 300cc achieved best results in all the parameters i.e. germination percentage (77.77), seedling height (7.98 cm), collar diameter (0.89 mm), fresh shoot weight (1.17 g), fresh root weight (0.64 g), total seedling fresh weight (1.80 g), dry shoot weight (0.62 g), dry root weight (0.46 g), total seedling dry weight (1.08 g), relative growth rate (RGR) (12.09 mg g-1 d-1), plant per cent (61.59), root : shoot ratio (0.74), sturdiness (8.90), Dickson’s quality index (0.108) which indicates that larger size container produced best quality seedling stock. The combined effect of growing medium and container size revealed that the best combinations which produced better results was M¬4C3 (Soil: Sand: FYM, 2:1:1- container/root trainer size- 300 cc). | en_US |
