Distribution and importance of Spruce (Picea smithiana) and silver fir (Abies pindrow) forests of Western Himalayas has been discussed. Regeneration problem of the spruce has been high-lighted. Seed collection, control against damping off and nursery technology of spruce has been discussed in details.

The results of an investigation conducted to study the effect of ischolar_main pruning on the survival and growth of transplanted silver fir seedlings showed that ischolar_main pruning improved ischolar_main:shoot ration, but did effect significantly neither the survival nor the growth of the seedlings; pruning of 75% of the tap ischolar_main, however, depressed growth of the seedlings slightly.- Germination of Populus ciliata Seed as Affected by Depth of Sowing

The result of experiments conducted to study the effect of the depth of sowing on germination of Populus ciliata seed showed that sowing on the surface gives the highest germination percentage and even the slightest covering of the seed by sand depresses germination.- Cuttings Taken from Bottom One-third Part of Populus Ciliata Plants Perform Better

Investigations carried out to determine the performance of cuttings taken from bottom one-third, middle one-third and top one-third portions of Populus ciliata plants showed that the cuttings taken from the bottom one-third parts of the plants performed better than those taken from the middle one-third which did better than those taken from the top one-third parts of the plants.- Effects of Nursery Density on Seedling Characteristics of Silver Fir (Abies pindrow Spach)

The investigations conducted to study the effects of density on seedling cbaracterstics of nursery - grown sliver fir showed that the collar diameter of Ihe seedlings decreased as the seedling density increased while the height of the dominant seedlings remained unaffected. The weight of stem, needles, ischolar_mains and total seedling and the volume of needles and ischolar_mains decressed with an increase in the seedling densiiy in the nursery.- Effect of Soil and Humus Mix on the Growth of Container Grown Spruce and Silver Fir Plants

Addition of humus In nursery soil improved the growth of seedlings of both spruce and silver fir and reduced ischolar_main : shoot ratio in spruce, but did not have any significant effect in this respect in silver fir.- Interception Studies in Cedrus deodara Loudon Plantation in Himachal Pradesh

The present investigations deal with the throughfall, stemflow and intercreption loss in Cedius deodara Loudon plantation (94.5% crown density) or about 35 years age at Shillaroo, Kolgarh Forest Division, Distt. Simla (Himachal Pradesh). Of the total rainfall (1850.1 mm) 2.9% (55.3 mm) stemflow, 71.8% (1328.5 mm) throughfall and 25.2% (466.2 mm) interception loss were recorded respectively by for the whole study period. The minimum interception loss (18.7%) was observed in the month of July, 1980 which had the maximum (370.2 mm) rainfall. The highest interception (69.1%) was recorded in the month of February, 1980. which had the lowest (7.0 mm) rainfall. Interception loss was decreased with the increasing amount of precipitation.- Distribution and Growth of Weeds as Influenced by Intensity of Felling in Spruce and Silver Fir Forests

The results of a study on the distribution and growth of weeds in spruce and silver fir forests worked under selection, shelter-wood uniform and clear-cutting systems are presented. The composition and relative dominance of weeds changed with the iutensity of fellings. The density and growth of weeds was the least in selection rorests and the highest in areas worked under clear-cutting system; areas worked under shelter-wood uniform system were intermediate in this respect. Total weed biomass. In clear-cut areas was 4 and 2.4 times that in those worked under selection and shelter-wood uniform systems respectively. Most of the weeds whose growth is encouralled by heavier felllngs grow tall and luxuriant and are harmful to the regeneration of spruce and silver fir.- Populus ciliata-a Promising Tree Species for Soil Conservation in Hilly Areas

One of the reasons for the important place of Populus ciliata in erosion control is tHat P. ciliata is one of the few species which can be successfully established from branch and stem cuttings. P. ciliata ischolar_mains easily in shallow soils where other tree species can not be established. Poplars are being used extensively for erosion control and (or the re-vegetation of eroded hilly areas in China, Japan, U.S.A. and New Zealand. P. ciliata has reasonably fast growth rate and strong spreading ischolar_main system. Plants Grown from cuttings produce and abundance of strong, thick lateral ischolar_mains with little taper.- Effect of Seedling Diameter on Growth of Transplanted Silver Fir Seedlings in the Nursery

'2.0', 2.0- <2.5 and 2.5 - <3.0 mm diameter. The performance of the seedlings of < 1.5 mm diameter both in term, of survival and growth was poorer than that of those of the remaining three classes which did not differ significantly from each other. Seedlings of < 1.5 mm diameter should, therefore, be called at the time of transplanting.

In an experiment conducted to study the effect of seedling diameter on the growth of transplanted silver fir seedlings in the nursery, studies were made on the growth and survival of seedlings of four classes, viz., < 1.5,1.5- <,'2.0', 2.0- <2.5 and 2.5 - <3.0 mm diameter. The performance of the seedlings of < 1.5 mm diameter both in term, of survival and growth was poorer than that of those of the remaining three classes which did not differ significantly from each other. Seedlings of < 1.5 mm diameter should, therefore, be called at the time of transplanting.
