The study was undertaken under Shorea robusta plantation in the foot-hills of Darjeeling Himalayas to observe the effect of timber operations on infiltration rate of the soil. The result revealed that due to movement of heavy trucks and dumping effects of heavy logs brings about a great compaction of the forest soil, in the timber operation site. Due to compaction of the forest floor, a reduction of soil porosity by more than 60% was noticed. There was also reduction in moisture-holding capacity due to disturbances. Initial (within five minutes) infiltration rate under undisturbed forest and disturbed forest by timber operation was 45.48 and 9.92 cm/hr respectively. Whereas it was 4.14 and 1.74 cm/hr at the end of a period of three hours. Accumulated infiltration in three hours was 36.05 and 7.64 cm in the undisturbed and disturbed site. The finding reveals that undisturbed sal forest having thick litter on its surface is much capable of intaking water. An efficient management should include guideline for avoiding heavy loads and retention of litter on forest floor for better soil and water conservation.

The experiment was conducted to study the effect of different levels of N, P and K on the growth of Robinia pseudacacia Linn. Seedlings under nursery corditions during 1987-88. The effect of different levels of N, P and K on shoot height, ischolar_main length, and coller diameter was found non-significant. Response to cliper growth was maximum at (N3, P3, (N376 P250 mg plant1), whereas N3, P2, K2, (N375 P250 K250 mg plant-1) gave maximum response to total biomass.- Present Status and Future Prospects for the Cultivation and Collection of Medicinal Plants of Himachal Pradesh

An attempt has been made to describe the present state of affairs with respect to the exploitation of medicinal plants in Himachal Pradesh. A case has been made out for standardizing package of practices for the collection, processing, marketing etc. of the important medicinal plants. Suggestions for taking up cultivation in forest areas and popularization of high yielding strains by carrying out genetic study has been made.- Experience in Breeding of Musk Deer for the Production of Musk

This article describes the occurrence, habitat and habits of musk deer with properties and uses of musk. Further it describes some results on musk deer faming and its 'milking' in the farm maintained at Kufri, Himachal Pradesh. It also suggests some items for research and observation in future.- Vegetative Propagation of Coniferous Forest Tree Species from Branch Cuttings with the Help of Mist chamber

The description of A Mist Chamber constructed at Simla has been given. The results of trials made with coniferous species like Pinus roxburgyhii, Pinus wallichiana, Pinus gerardiana, Cedrus deodara, Abies pindrow and Picea ,emythiyana have been given. Except Pinus gerardiana all the species have been ischolar_mained. The studies. Have indicated that mist chambers are very usleful in ischolar_maining coniferous species.- Study of Soil Micro-morphology with Special Reference to Soils of Fir Zone of Kulu
