Abstract
An experiment was conducted at College of Forestry, Sirsi, during 2015-16, to study the effect of pre-sowing treatments on seeds, effect of storage conditions on seed quality and Integrated Nutrient Management in quality seedling production of Flemingia semialata.
Seeds scarified with concentrated sulphuric acid for one minute recorded significantly higher germination 76.25 per cent, germination rate (7.32), mean daily germination (2.72), total seedling length (18.12 cm) and seedling vigour index (1380.74). In poly house significantly higher field emergence 73.00 per cent and germination rate (2.90), mean daily germination (2.60), total seedling length (15.56 cm) and seedling vigour index (1135.88), followed by seeds treated with KNO3 0.2% for 12 hours.
Among the integrated nutrient management treatment constituting common potting media (soil: sand: FYM of 2:1:1) along with Arbuscular mycorrhiza (AM) (10 g) + phosphate solubilizing bacteria (PSB) (5 g) + NPK (2 g) influenced the growth parameters viz., seedling height, collar diameter, number of branches, number of leaves, fresh weight and dry weight of the plants significantly and considered to be best compare to other treatments followed by treatment constituting AM + PSB + NPK (19:19:19) 1g/plant.
The seeds stored in four different containers and kept under two storage condition showed progressive decline in seed quality parameters with the advancing storage period. On an average the germination percentage recorded at the beginning and end of storage period was 70.00 % and 52.08 % respectively. Seed stored in cloth bag kept in cold storage was found to be better seed container for storing seeds with relatively more viability.
