Physical and chemical properties of three soil profile were studied under the Pinus patula plantations of eastern Himalayas. Interrelationships of these soil proflies have been discussed and compared to that of Western and Central Himalayas. It has been tried to find out that how leaching proceeds in the process of getting maturity of soil profiles as the forest becomes old. Attempts Were made to classify the soil type of this region. In short the soil is brown in colour with sandy loam texture which undergoes in the process of podsolizatlon. It is also called Inceptisol which shows little evidence of eluviation and illuviation. Organic matter decompose slowly due to the cool and humid climate. This results relatively higher (38.31) Carbon-nitrogen ratio. Effect or forest cover on soil properties shows that Pinus patula soils are poor in mineral concentrations.- Biological Productivity of Shorea Plantations

Even-aged series of Shorea plantations are investigated for evaluation biological production. Leaf area index and stand basel area of have reached peak values over 18 years of tree growth. Tree biomass of 137 ton/ha and net primary productivity of 14.62 ton/ha/year are reported for sal plantations in Tilkonia range, Gorakhpur Forest Division. Effects of stand age on biomass production, distribution and production ratios are documented for man made forests of sal. Sal stands belonging to advanced ages (40-70 year) need further study to definitely establish trends of annual productivities in relation to age sequence.- Root Development in Alluvial Grasslands of Varanasi
