Axle wood (Anogeissus latifolia Wall.), a principal forest tree species of the sub-tropical and tropical forest ecosystems was used to study the effect of collection dates and diameter classes on per cent viability, insect pest infestation and germination attributes of its seeds. Diameter classes only influenced the viability status and insect-pest infestation significantly. In the diameter classes, maximum viability (33.67%), per cent germination (1.73%), germination energy (1.20) and germination value (0.158), and minimum insect-pest infestation (5.87%) was recorded in 21-30 cm diameter. The collection dates significantly influenced all the studied traits, excepting germination value. Maximum per cent germination (2.00%), germination energy (1.33%) and germination value (0.145%), irrespective of tree-diameter class was recorded in seeds collected in the 2nd half of March. Therefore, from the present investigation it can be concluded that under Himachal Pradesh conditions, seeds should be collected during the 2nd half of March, from 21-30 cm diameter class for realizing maximum germination potential.

Ban Oak (Quercus leucotrichohora Camus), a principal forest tree species of North-West Himalayan forest eco-system, was used to investigate the effect of chemical treatment, season, donor plant and shoot position on ischolar_maining and primary ischolar_main number, and subsequent survival of the ischolar_mained cuttings. The per cent ischolar_maining and primary ischolar_main number improved markedly upon application of chemical treatment. maximum per cent ischolar_maining (35.25) was recorded in the rainy season planted seedling cuttings treated with chemical formulation of 0.8% IBA + 0.2% p-HBA + 5% sucrose + 5% captan. Irrespective of chemical treatment, season and position, seedling cuttings demonstrated significantly better per cent ischolar_maining and primary ischolar_main number than tree cuttings. Primary ischolar_main number were more in lower portion of the shoot cuttings, while per cent ischolar_maining was higher in cuttings collected from the upper portion of the shoot. The seedling cuttings collected from upper portion of the shoot during rainy season displayed better survival than others. From the present study, it can be concluded that for achieving maximum ischolar_maining and survival of the ischolar_mained propagules, the cuttings should be collected during rainy season from the upper portion of the seedling shoot and treated with chemical formulation of 0.8% IBA + 0.2% p-HBA + 5% Sucrose + 5% Captan.- Effect of Growing Media and Inorganic Phosphorus on Growth and Development of Maggar Bans (Dendrocalamus hamiltonii Munro) Planting Stock

Studies were conducted to investigate the effect of five growing mediums and four levels of inorganic phosphorus on the growth and development of Dendrocalamus hamiltonii planting stock under mid-hill conditions of north-western Himalayas. The growing medium and phosphorus levels significantly influenced various growth and development traits individually as well as in combinations. The growing medium viz., sand + soil + FYM (1:1:1) proved to be significantly superior for enhancing height and diameter growth of the tiller's, number of tiller per sapling, number of nodes per tiller, number of ischolar_mains, length of ischolar_mains, number of rhizomes, dry weight of stem, ischolar_mains, rhizomes and underground biomass. Among the various levels of phosphorus, 5 g SSP/propagule significantly proved to be the best dose. In combination effect, the maximum dry weight of rhizome (2.82 g plant-1 ) and underground biomass (9.69 g plant-1 ) was recorded in the propagules grown in sand: soil: FYM (1:1:1 ) and supplied with P @ 5 g SSP/propagule.Keywords

The present work aimed to study the regeneration status, species composition in natural and plantation forests of subhumid tropics in Barnawapara Wildlife Sanctuary during 2009-2010. A total of 33 species of 17 families were encountered. Regeneration status in all the study sites were dissimilar. Closed natural forest (960 stems/ha of seedlings and 220 stems/ha of saplings) displayed the better regeneration followed by open natural forest (350 stems/ha of seedlings and 90 stems/ha of saplings) and teak plantations (340 stems/ha of seedlings and 40 stems/ha of saplings) respectively. However under teak plantation Lagerstroemia parvilora has shown better regeneration. Tree stand density varied from 520 to 990 stems ha-1 having basal area ranging from 21.50 to 47.30 m2 ha-1. It is evident that natural forest has an edge over plantation forest in terms of regeneration, species composition.Keywords

Dendrocalamus hamiltonii Munro was evaluated for the effect of month of planting, spacing and phosphorus application on survival, growth, rhizome-genesis, biomass partitioning and P-uptake in macro-proliferated stock. April planted propagules significantly excelled over July ones for all of these traits. Two to three times more dry biomass of stem, ischolar_mains, rhizome and underground biomass per sapling (g) production was recorded in April planted propagules as compared to propagules planted in July. P-uptake was also higher in April planted propagules than July ones. Spacing of 30 cm × 30 cm resulted in maximum growth, development, biomass production and biomass partitioning and Puptake than 30 cm × 15 cm and 15 cm × 15 cm spacing. Phosphorus application @ 5 g SSP per propagule resulted in maximum growth, development, rhizome-genesis, dry weight of stem and underground biomass. Higher dose i.e. 10 and 15 g SSP per propagule showed slight depressing effect.Keywords

Trees are known to maintain soil organic matter and nutrient cycling through the addition of litter and ischolar_main residues into the soil. There is a large potential of sequestering carbon in soil and vegetation by adopting suitable agroforestry systems. The present investigation was conducted during January-June 2007 at Poanta valley of Himachal Pradesh, located at an elevation of 350 m amsl. Six agroforestry systems were selected viz. hortipastoral system (HP) (Mango + natural grasses), silvi-pastoral system (SP) (Dalbergia sissoo+ natural grasses), agri- silviculture system (AS) (Sal + wheat), horti-silvipastoral (HSP) (Mango+ Poplar + natural grasses), Pure Forest (F) (Sal), natural grass land (NG) (pure grasses). At 0-20 cm depth, soils under natural grassland was having higher bulk density (1.28g cm-3 ) among all the systems while lowest bulk density (1.16 g cm-3 ) was observed under forest. In 20-40 cm depth, the results also showed significant variation at 5% level of significance. Soil organic carbon (SOC) at the soil depth 0-20 cm was highest under forest (3.64 %) while silvi-pastoral system showed the lowest (1.30 %). In general, SOC pool in the 0-20 cm layer was quite higher than that of 20-40 cm layer. The total SOC pool for different Agroforestry system followed the decreasing order as PF (1373.7 Mg ha-1) > HSP (719.6 Mg ha-1) > AS (697.3 Mg ha-1) > NG (696.5 Mg ha-1) > HP (646 Mg ha-1) > SP (599.10 Mg ha-1).Keywords

Eight predominant land use systems, viz. agriculture (T1), horticulture (T2), agrisilviculture (T3), silvopastoral (T4), agrihorticulture (T5), agrihortisilviculture (T6), forest (T7) and grassland (T8) of subtropical parts of Himachal Pradesh were selected along two altitudinal ranges A1 (365–635 m amsl) and A2 (636– 914 m amsl) to observe the variation in soil microbial activity and microbial characteristics. Agroforestry land uses and forest ecosystems displayed significantly higher microbial counts and microbial biomass carbon than agriculture and grasslands. The CO2 evolution (soil microbial activity) was found higher in agrisilviculture, agrihortisilviculture, forest and grass-land use systems at both altitudinal ranges. Soil biological properties (microbial count, microbial biomass and microbial activity) were maximum in forest landuse system. Among the agroforestry land-use systems, agrisilviculture had significantly higher microbial counts. The maximum microbial count (164.50 × 105 cfu g–1 soil) was recorded in forest and remained statistically at par with agrisilviculture (162.34 × 105 cfu g–1 soil). Minimum microbial count (80.66 × 105 cfu g–1 soil) was observed in agriculture land use. At both the altitudinal ranges, the CO2 evolution was highest at 48 h time interval and decreased thereafter. The metabolic quotient (qCO2) indicated that C-use efficiency is higher in grassland use and agriculture land use systems than other studied systems.Keywords
