Three major tree communities were identified in the Satpura National Park, Madhya Pradesh i.e. Chloroxylon-Terminalia community at elevation range <900m (Lower hills). Shorea - Terminalia community at 900-1100m elevation (Middle hills). Syzygium- Terminalia community at 1l00-1350m elevation (Upper hills). There was decrease in density with increasing altitude. On the hasis of basal area and density Shorea robusta preferred the mid hills, Chloroxylon swietenia performed better at lower bills and Syzygium cumini preferred to grow in upper hills. The distribution pattern of species is contiguous. Diversity index of tree species in three plant communities i.e. Chloroxylon-Terminalia, Shorea-Terminalia and Syzygium-Terminalia was 3.62, 2.71 and 3.02 respectively. High species diversity is an indication of maturity in the ecosystem. The tree species richness was 45, 29 and 31 at <900m, 900-1100 m and 1100-1350m elevation respectively. Forest belonging to Chloroxylon-Terminalia is biodiversity rich area because of more number of species. There are 29 shrub species under Chloroxylon-Terminalia, community followed by 27 shrub species under Shorea-Terminalia community and only 19 shrub species under Syzygium-Terminalia community. In corresponds to species diversity index of 3.85, 3.16 and 2.57 respectively. Diversity index of herbs in these communities was 3.53,3.44 and 3.26 respectively, which corresponds to herb species richness in term of individual members of 43, 40 and 37.- Phytosociological Study of Navegaon National Park (Maharashtra)

Vegetation studies were conducted in the Navegaon National Park in order to assess the floristic composition. The forest is composed of 40 species of trees, 16 species of shruhs and 44 species of herbs. Three plant communities were identified, namely (1) Tectona-PterocarpusBuchanania, (2) Cleistanthus-Ougeinia-Tectona, and (3) Cleistanthus-Lagerstroemia-Terminalia; corresponding to three elevational ranges, i.e. 300-400m, 400-500m and 500-600m, respectively. Cleistanthus collin us is the most dominant species with density 3711ha followed by Tectona grandis 175/ha. Biotic disturbances were observed at lower elevation which has resulted in the absence of Raunkiaer's normal frequency distribution. Measures are suggested to restore the density and protect the ecosystem.- Severe Infestation of Mistletoe on Gmelina arborea (Roxb.) in the State of Mizoram

A pot experiment as conducted to study the effect of some salts on the soli reaction and the growth and dry matter yield of Leucaena leucocephala and Acacia auriculiformis. Addition of FeSO4 slightly decreased the soil pH whereas CaCO3 and Na2CO3 increased it. Application of FeSO4 decreased the plant height. In case of Leucaena leucocephala more at earlier stage whereas it increased the height of Acacia auriculiformis. Addition of CaCo3, decreased the height of both the species. The application of CaCO3, along with Na2CO3 had seriously affected the growth and survival of these two species.The dry matter yield of both the species was enhanced with the addition of FeSO4. The application of CaCO3 @ 10g/kg soil, increased the dry matter yield of Leucaena leucocephala whereas the yield of Acacia auriculiformis remained alomost unaffected. Further increase in the level of CaCO3 applied alone or with Na2CO3 reduced the dry matter yield of both the species. Added FeSO4 and CaCO3 at lower dose, increased the dry weight of ischolar_main nodules and further increase in the level of CaCO3 decreased the nodule weight.- Studies on the Growth Performance of Some Green Manure Leguminous Crops and their Residual Effect on the Organic Matter and Available Nutrients in Eroded Teak Nursery Soils of Nainpur (M.P.)

A field experiment was conducted on eroded teak nursery soil of Nainpur (M.P.) to study the growth performance of some green manure leguminous crops and their residual effect on organic matter and available nutrients. The order of obtaining maximum dry matter yield/plant was Arahar> Chakora> Soybean> Urd> Moong> Sannhemp. The average number of nodules/plant was maximum in Moong and Sannhemp at the intervals of 30 days and in Soybean and Arahar at 60 days interval. Number of nodules in all the leguminous crops decreased as the crop approached to maturity. The green manuring added the organic matter in surface soil treated with moong, soybean and sannhemp and increased the availability of soil nitrogen and phosphorus in surface and sub-surface layers in all the treatments. No appreciable changes in available potassium has been noticed in surface soils but a significant decrease was observed in sub-surface layer in all the treatments over control.- Effect of Nitrogen and Phosphorus Fertilization on Dendrocalamus strictus Seedlings

An poly-pot experiment was conducted in factorial R.B.D. design with 4 replications to study the effect of nitrogen and phospborus on the growth and yield of bamboo seedlings. Application of nitrogen @ 5.0 gm and 10.0 gm of urea/pot containing 2 kg soil individually as well as in combination with single superphosphate significantly decreased all growth parameters and dry matter yield. However, phosphorus application @ 10.0 gm and 20.0 gm single superphosphate/ pot individually as well as in combination with nitrogen increased the height of plant, length of rhizome and dry matter yield. The correlation coefficients between some growth factors were calculated and were found highly significant. The results of this experiment suggest that with 'P' application better growth of bamboo seedlings may be obtained in short duration and healthy plantation stock could be made available.- Afforestation of Salt Affected Wasteland I-screening of Forest Tree Species of Madhya Pradesh for Salt Tolerance

Germination studies on the seeds of four forest tree species viz. Dendrocalamus Strictus (Bamboo) of Betul and Amarkantak origin, Emblica officinalis (Awala) and Acacia auriculiformis (Australian Babul) were performed in different artificially prepared saline water of 3, 6, 9, 12 and 18 mmhos/cm electrical conductivity adjusted in Hoagland solution 1 by incorporating neutral salt, NaCl. Tap water was the control whose Electrical conductivity was .56 mmhos/cm and fresh Hoagland solution contained 1.76 mmhos/cm E.C. Germination data were subjected to statistically analysis with 7 treatments and 8 replications in factorial design. Eamtoo may tolerate higher salt concentration. Bamboo of Amarkantak origin may prove to be better In high salinity conditions, however the same may be very detrimental for the germination of Awala. Australian Babul may not fair well in salt affected conditions.- Performance of Sal (Shorea robusta) on Soils Derived from Different Parent Materials in Shahdol forest Division, M.P.

Performance of Salon soils derived from sand stone, granite, trap with lateritic bricks, deccan trap and mottled nodular bed of limestone was studied in Shahdol Forest Division, M.P. According to phytosociological considerations Shorea robusta- Madhuca indica, Shorea robusta-Terminalia tomentosa, Terminalia tomentosa- Lagerstroemia parviflora and Terminalia communities were found on sand stone, trap with lateritic bricks, deccan trap and limestone respectively. Sal (Shorea robusta) had maximum frequency, density, basal area and also IVI on soils derived from sand stone and minimum on soils derived from limestone. This differential response of salon sand stone (and also granite) was explained on the basis of physico-chemical properties of the soils. Sal prefers soil low in pH (5.4 to 6.5), low in electrical conductivity (∠ 0.1 mmhos/cm), low in Exch. Ca (3 to 10 meq/lOO gm), low in Mg (1 to 4 meq/100 gm) and also low in C.E.C. (6 to 20 meq/l00 gm).- Growth of Teak Seedlings in Nursery

A Pilot experiment was conducted to know the effect of N P K on the growth of teak seedlings in nursery stage. Due to high fertility status of nursery beds, fertilizer treatments were not significant. However, data revealed that teak seedlings may become of transplantable size within 4 months duration. A four month old teak seedling produced shoot and ischolar_main of about 116.72 gm and 42.33 gm respectively. Shoot height of this seedling was 41.84 cm while as ischolar_main length was 48.13 cm. Girth size at collar was 4.75 cm. This is possible by maintaining adequate fertility status by incorporating F.Y.M., inorganic and organic fertilizers. There is no need of adding growth hormones. Shoot/Root ratios of fresh weight and also of length of teak seedlings tended to approach one in September and October (Sixth and Seventh month after sowing) in heavy textured soil.- Effect of Forest Covers on Physico-chemical Properties of Soils Developed on Sand Stone

Physico-chemical properties of soils belonging to great group of Haplustali/Hapiustoli and developed from Gondwana land stone in similar physiographic and environmental conditions were studied under three forest covers Viz., miscellaneous cover, teak plantation and Eucalyptus cover in Kotma and Ghunghuti ranges of South Shahdol and North Shahdol Divisionl of M.P. respectively. Weathering processes seem to be quite active in soils under followed by Eucalyptus cover. Ratios of clay to non clay fractionl, thickness of 'A' horizon, per cent organic matter, cation exchange capacity, exchangeable Ca and Mg were more under teak cover than that of Eucalyptus. Soil pH lowered down more under Eucalyptus plantation than in teak plantation. Soluble salts were more under Eucalytus cover. Performance of Eucalyptus was better on Ghunghuti range where as teak was better on Kotma rangue Eucalyptus supports undergrowth of different tree species.- Structural Composition and Productivity Assessment of the Grassland Community of Kaziranga National Park, Assam

Grassland communities of Kaziranga National Park (KNP) classified as Eastern Wet Alluvial Grasslands. It comprised of tall grasses (61%) as well as short grasses (only 3%). Rapid periodic changes occurred due to recurrence of flood, erosion and alluvial deposition and have direct implications for the establishment of early successional species. Grassland can be viewed in terms of upland grasslands and lowland grasslands. Apluda mutica, Arundinella bengalensis, Imperata cylindrica, Thysanolaena maxima, Saccharum spp., Vetiveria zizanioides, characterize the upland grassland and the lowland grasslands comprise predominantly of Phragmites karka, Imperata cylindrica, Saccharum spontaneum, Arundo donax and Saccharum narenga which considered being early successional species. Seven tall grasses and three short grasses communities have been identified. Above ground biomass increased from June to October due to rapid growth after the commencement of monsoon rain and declined during the winter months. The peak growth rate of total above ground biomass (31.94 g m-2 day-1) is much higher than the other grassland types reported elsewhere in India. Frequent burning resulted drier habitat and Pharagmites karka was replaced by Saccharum, Sclerostachya, Themeda and Imperata species. Excessive grazing favours the establishment of unpalatable species like mperata cylindrica, Vetiveria zizanioides etc. and several pure stands of these grasses developed.Keywords
