The present study deals with the effect of cone collection date on seed and germination characteristics in blue pine (Pinus wallichiana). The first cone collection was done on 15th September, second on 30th September, third on 15th October and fourth on 30th October from Gangotri range of Uttarkashi Forest Division of Garhwal Himalaya. Percentage of viable seeds, per cone increased while percentage of non-viable seeds per cone decreased with the maturity of cone. Mean fresh weight of 100 seeds increased from first to fourth (last) cone collection date. The moisture content of seeds decreased while seed germination increased as cone collection dates progressed. Germination per cent and germination value of seeds steadily increased from cone collection date of 15th September to 30th October. Therefore, the cones should be collected in the last week of October to obtain quality seeds.Keywords

An experiment was conducted to study the effect of organic manures on germination and growth behaviour of khirni seedlings. The experiment comprised of eight media formulated by mixing soil, sand, FYM, vermicompost, poultry manure, cocopeat and spent mushroom compost in different combinations. The study indicated that seed germination and seedling growth parameters of khirni seeds were greatly influenced by the growing media. The results revealed that the combination of Soil + Sand + FYM proved superior in terms of seed germination, seedling length, number of leaves, ischolar_main length, ischolar_main dry weight, seedling dry weight, seedling vigour index-l and II whereas greater shoot length, stem diameter and dry weight of shoots were recorded in the media containing Soil+ Sand+ Vermicompost..Keywords
