Single tree volume tables for tropical pines (M.P.) have been prepared using the regression equation: Ln v = 0.0001715 + 2.312 Ln d. This was compared with other regression equations and was found most suitable and widely applicable. The results obtained were highly significant. Number of stems/ha, basal area and volume/ha were also calculated with confidence at 95% probability (P=0.05).

A trial was carried out to study the effect of polybag size and number of perforations at the bottom on different seedling growth and quality parameters in case of Albizia procera seedlings raised on Mounted Angle Iron beds. Highly significant differences in seedling growth parameters viz., height, collar diameter, length oftap ischolar_main, ischolar_main and shoot biomass, and seedling quality parameters viz. sturdiness, ischolar_main/shoot ratio, number of nodules and ratio of secondary + tertiary ischolar_main biomass to total ropot biomass, were observed among different treatments. The treatment T3 (Polybag size 23 x 11 cm with 4 perforations at bottom) performed the best in respect of seedling growth parameters with height 81.33 cm, collar diameter 0.76 cm, length of tap ischolar_main 16.90 cm, shoot biomass 14.36 gm and ischolar_main biomass 11.67 gm. However the treatment T12(Polybag size U x 6 cm with 6 perforations at bottom) recorded best values for most of the seedling quality parameters viz. sturdiness 82.03, ischolar_main/shoot ratio 1.21 and ratio of secondary + tertiary ischolar_main biomass to the total ischolar_main biomass 0.44.- Leaf-shedding and Emergence Pattern in Five Clones of Populus deltoides Marsh under Central Indian Conditions

Newly introduced five clones of Poplar (Populus deltoides Marsh) from Northern India to Central India, were studied for their leaf shedding and emerg.::mce behaviour during winter and spring seasons. The clones namely G-3, G-48, D-121 and S7-Cl remained in complete leafless condition for 2, 5, 7 and 6 weeks respectively. The leaf emergence in these clones started in first week of March and rapid leaf formation was recorded in subsequent weeks during March and April. The clone 65/ 27 has maintained its evergreen status under Central Indian conditions with minimum no. ofleaves during the months of January and February. These observations suggest the existence of a very short deciduous period in all the clones under Central Indian conditions. It has been further suggested that the deciduous condition has definite role in deciding the suitability of the clone under tropical conditions of Central India.- Euproctis subnotata Walk.

The influence of different pit sizes with or without fertilizer application on survival and growth of thirty months' old Cassia siamea in degraded soil was studied. The survival and plant height significantly increased as tlie size of pit increased with or without fertilizer. Urea over 25 g pit-1 applied in smaller pits < 30 cm3 ) adversely affected the survival of plants, where as, response of phosphorus as a whole was observed to be positive. Among forty possible treatment combinations (5 pit sizes and. 8 fertilizer levels) the best treatment combination was 45x45x60 em pit size with 75 g urea and 75 g single superphosphate per pit for better survival and higher growth of plants.- Considerations of Demand-patiern and Economic Return on forest Management and Rationalisaton of Pricing of Timber (teak)

Investments in forestry plantations are long term investment. In such ventures/projects the tree growth is limited by the natural factors, whereas growth of money is governed by numerous market forces. For optimal returns form forestry plantations,it is necessary to follow a management scheme/plan which is evolved after considering the implications of demand-pattent, rate of tree growth and economic retun in terms of sustainable utilization. For sound economic sustainability, it is also essential that there exists a rational basis for pricing of the final product i.e., timber. In this paper an attempt has been made to study and analyse the above concept by taking an example of a teak plantation and using the figures as observed in the Timber Market Survey conducted at Jabalpur.- Increasing Hydrological Hazards in the Himalayas: Defence Lies in Integrated Scientific Preparedness
