Abstract

Phenological studies on Azadirachta indica A. Juss (Neem) of different agro-climatic zones viz Narmada valley, Vainganga valley and Satpura plateau are described. Major leaf-fall period fell between February-March except in Narmada valley where it was extended up to April. Leaf emergence initiated during February-April in different agro-climatic zones. Vegetative phase lasted for seven months (August-January) in all climatic zones except Vainganga valley where it lasted for six months only. Flowering initiated in February in all the climatic zones while in Narmada valley, it was noticed during March. Fruiting was initiated during March-April. The impact of climate was observed on the morphological and phenological characteristics of Neem. The significant variations among the quantitative phonological parameters like leaf, flower, fruit-abundance, leaf-area, leaflet area and leafweight for different climatic zones. These variations were non-significantly correlated with growth-parameters like gbh, tree-height, crown-diameter and crown-height. Significant positive correlation between flower and fruit- abundance was obtained which indicated that increasing flower-abundance enhanced fruit production.

Abstract

Spatial variability of surface soil pH and organic carbon was studied in perpendicular transects at sites in near Jabalpur (M.P.) put to bamboo based agroforestry models and compared to control for two continuous years. The land under present study was degraded and occurs in a continuous path. Though, there was no systematic pattern of variation of values of pH and organic carbon in different directions, there was slightly less variability in North-South direction as compared to East-West direction. Overall, heterogeneity was found to be more in the first year than second year (i.e two seasons of agro-forestry land use). Shrubs and herbs invaded through bamboo based agroforestry practices in the degraded sites form the center of influence from which soil properties vary spatially.

Abstract

In the present communication , the impact of different management systems on biodiversity conservation in Abhoya of Midnapore District of West Bengal (India) has been assessed. Vegetation survey of plant communities and distribution pattern were conducted through Important Value Index (IVI) in three types of forest communities , such as FPC-managed forest , plantation stand (1960) managed by State Forest Depari:ment and degraded forest. These surveys covered four major seasons viz. summer , monsoon , post-monsoon and winter in this region. Maximum number of species were observed during post-monsoon and in FPCmanaged forest. The coppice Sal forest , which is the predominant natural forest type of this region , S. robusta has become the dominant tree with-varying IVI in different communities. Herbaceous species were found to be more adapted to a developing community like coppice Sal forests than a plantation stand or a degraded forest. Comparing different phytosociological parameters , FPC-managed forests were found to have more diversity in species structure irrespective of seasonal variations , whereas in plantation stand and degraded forest the species diversity becomes lower. The concentration of dominance was observed inversely proportional with species diversity. Highest evenness index was calculated maximum for FPC-managed forests and during post-monsoon or monsoon. Species richness index did not differ significantly among three communities and in four seasons. Based on IVI values the abstract community in Abhoya was identified as Shorea-Holarrhena-Eragrostis. The study indicates that involvement of forest fringe people in protecting the forest through JFM can increase the forest cover. It is better to study the phytosociological characters in post monsoon period.

Abstract

Medicinal plants form an integral part of rural and urban lifestyle. But many of the species have reached the stage of 'endangered and threatened' because of over-exploitation of forests, uncontrolled grazing and fire. In India nearly 175 million ha of land is degraded, out of which 93 million ha is lying waste. This land is not suitable for growing agricultural crops economically but can be effectively used for growing medicinal plants after proper management. In this review, species suitability for different types of wastelands, proper amendments for boosting the growth of these plants etc. have been discussed in length.

Abstract

Attempts have been made to study the impact of flyash generated from Shaktinagar (UP) Thermal Power Plant on foliar chemical and biochemical parameters of Ipomea cornea, Cassia tora and Acaica nilotica naturally growing on flyash dyke. The present study also aims at assessing performance of different tree species planted in a 12 years old flyash dyke and ground cover development in the plantation area. From the results, it is apparent that flyash severely affects the plants by changing the chemical (N, P, K, Ca and Mg) and biochemical (protein, carbohydrate, chlorophyll, ascorbic acid compositions). Protein, carbohydrates, chlorophyll and ascorbic acid decrease significantly with a significant increase of phenols of the plant species grown on flyash (N, P, K, Ca and Mg also decrease when compared to control). Since major part of the ash comprises Si0₂, AI₂ 0₃ and oxides of iron and other toxic metals, these oxides are absorbed by the leaves through stomata when the ashes are deposited on the leaves and also through uptake of the oxides by ischolar_main systems. The increase of phenols helps in imparting resistance to the plants against stress conditions and insect attacks. The results also reveal that although the flyash is refractory in nature, it can well respond to some species if planted after its stabilization which normally takes 4 to 5 years. Species like Gmelina arobrea, Grevillea pteridifolia and Emblica officinalis are more suitable for planting this site both with respect to amelioration and biomass production. However, other species likeAlbiziaprocera, Albizia lebbek, Azadirachta indica, Acacia catechu, Prosopis juliflora etc. may also do well. Planting of these species results induced succession development in which Tephrosia- Desmodium-Polygonum have been found to be the stable community and these three species share the major niche space.

Abstract

Land degradation is a global phenomenon. Endless desires of man have put enormous pressure on this valuable natural resource. India is reported to have 175 million ha of land under various stages of degradation. Deforestation and improper land management are the main reasons. The great diversity in topographic conditions is responsible for an annual loss of about 6000 million tonnes of top fertile soil. Any improvement programme concerning soil health can not be achieved unless it incorporates soil and water conservation. Studies were conducted to assess improvement in soil properties due to adoption of soil-water conservation method (staggered trenching) on hilly slope in Jabalpur District of Madhya Pradesh , India. At site I Tectona grandis was planted at 2 m × 2 m spacing and in between rows staggered trenches of 3 m × 0.5 m × 0.5 m were dug. Observations recorded after 4.5 years of planting showed considerable improvement in soil properties , more so on the lower slope in respect of organic carbon , available nutrients (N , P and K) etc. Soil loss has also been reduced to a considerable extent. At site II Albizia procera and Albizia lebbek were planted and soil-water conservation measures were adopted in a similar way as at site I. This site also showed remarkable degree of improvement in soil properties at 4.5 years of age. Originally both sites were having highly eroded surface and the soil depth was as less as 15 to 20 cm underlain by hard rock and morrum. The soils were quite deficient in nutrients and were having low water building capacity. The growth of planted species was significantly higher than control.

Abstract

An attempt has been made to analyse chemical and biochemical characters of Neem leaves from eleven agroclimatic regions of Madhya Pradesh , Chhattisgarh and Orissa and correlate them with soil properties and geographical ordinates so as to obtain maximum productivity of desired character from that site or artificial induction of suitable environment for better productivity and the desired characters. The data revealed that the amount of leaf protein varied from 8.76 to 15.48% and polyphenols from 2.42 to 7.10%. The marginal variation in leaf nitrogen (1.35 to 2.47%) of different sites indicates that uptake potential and availability of nutrients are almost similar. Polyphenols showed significant negative relation with soil p^H , calcium content in leaves and available soil nitrogen. From the results it may be concluded that Neem trees are suited in slightly alkaline soils having better available nutrient status. Environmental and edaphic factors as well as geographical latitude play significant role in increasing productivity of the tree.

Abstract

Different age group plantations of Gmelina arborea Linn. In Western Maharashtra, were evaluated for monitoring the status of pests. These plantations have suffered due to mortality caused by some biotic factors i.e. grazing, hacking, faulty pruning, rab firing, diseases, insect pests viz. defoliators, leaf miner, bark eating caterpillar, phassus borer, sap suckers, canker grub, weevil, termites etc. In this study, the impact of different pest outbreaks was evaluated on Gmelina arborea mortality. In this regard, observations were recorded on the pest incidence, their relationship with soil nutrients and different girth and height classes. Additional scenarios included possible measures to counter the present problem are also suggested.

Abstract

The phyto-sociological aspects of the highly degraded basaltic tract of Jabalpur, Madhya Pradesh were studied to assess the impact of Agro-forestry models of Bamboo cultivation with the short term agricultural crops on the restoration of ecology. The ground flora was recorded at four Agro-forestry sites with a control in October, 1996 and 1997. The results obtained from the study revealed that there was considerable increase in number of species, diversity index and species richness as compared to control in both the years. The increase was more conspicuous in the second year. Poaceae was found to be the dominant family on all the sites. Reduction in number of species at the control site has been attributed to the heavy biotic interference. The ecological parameters studied revealed that the degraded agricultural lands can be ecological restored and improved fast through the development of Bamboo based Agro-forestry models.

Abstract

The dependent changes in species composition, nutrient status and biological activity of manganese mine overburden spoils of Ukwa, Balaghat District of Madhya Pradesh in relation to age have been assessed. The results indicate that the number of species increased as a function of the age of the overburdens. A good number of leguminous species was observed in different sites which is an indication of gradual improvement of the fertility status ofthe spoil. As the overburden got invaded by vegetation with time organic carbon and nitrogen went up with a peak in natural forest area. Available P and available K also increased significantly with the increase of the age spoils. The population of all the organisms (bacteria, actinomycetes and fungi) increased sharply with the increase of the age of the overburden. A highly significant positive correlation was obtained between the number of plant species and organic carbon of the spoils. Significant positive correlation was also obtained between the number of organisms and organic carbon, total and available nitrogen, available P and available K.

Abstract

The objective of this study was to utilise various tree leaves for biogas production and to compare the potentiality among the various leaves for producing biogas. It was found that digester slurry with leaves and cowdung at 8% total solid concentration would be the optimum concentration for better and efficient biogas production. At 8% slurry level, Leucaena leucocephala leaves with cowdung at 1:1 ratio produced maximum amount ofbiogss with lower percentaee of methane. Up to 35 days of digestion Acacia auriculifarmis leaves produced 41% more gas in total than cow dune and Leucaena leucocephala produced 18% more. In respect ofVFA concentration and degree of volatile matter degradation Dalbergia sissoo is also capable of yeilding biogas. But very high concenteration of VFA and low pH retarted the activities of methanogens. Eucalyptus leaves has
proved to he hardly degradable for biogas production. The high content of volatile solid and hollocellulose and highest C:N ratio justify its hard nature.

Abstract

Morphology and physiochemical characteristics of three soils within the altitudinal range of 315 to 1490m under different vegetal cover of South Sikkim forests are discussed. The soils are acidic with fairly high content of organic matter and total nitrogen. Exchangeable calcium is maximum at the surface of all the soils and highest under mixed broad-leaved species. Humic acid content decreases down the profile. The properties of the three soils differ fairly widely and the difference can primarily be attributed to differences in physiograpby reflected through differences in vegetal cover and ultimately in the resultant soils. The three soils have been classified upto sub-group level according to Soil Taxonomy.

Abstract

Soil of quality class I Eucalyptus tereticornis in South Bengal have been studied for their morphological characteristics and physicochemical attributes. The soils are acidic and poor in organic matter. The sudace soils are light but clay translocation is common in most of the profiles. The chemical composition of the soils has been influenced to a great extent by drainage condition, differential transport of eroded material, leaching, translocation, redeposition of mobile soil constituents and formation and abundance of mottles. Chemical composition also indicates trends of laterisation of organic matter and break-down of parent material into free silica and sesquioxides.

The chemical composition of these soils has been influenced to a great extent by drainage condition, different transport of eroded material, leaching, translocation and redeposition of mobile soil constituents. Chemical composition of the soils indicates trend in laterisation process. Appreciable base status of the soils, however, goes to prove that weathering has not progress so far.

Abstract

Investigation on the soil properties of the darjeeling Forest Division(W.B.) was carried out to see the changes due to different forest vegetations (Pinus patula, Cryptomeria japonica, tectona grandis, Shorea robusta and mixed broad leaf species). Highest content of organic matter and lowest soil pH were noticed in the site of C. japonica plantation; calcium content was maximum in teak(Tectona grandis) area. The solls under C. japonica had minimum total bases nad teak the maximum and more than half of the total bases in teak area was contributed by calcium. Mixed vegetations reflected best performance on soil properties among the plantations undertaken in the present investigation. Results showed that vegetational cover affects the soil properties and it is suggested that in order to maintain natural ecological balance and avoid drastic changes in soil properties, mixed plantation should be prefferred to pure plantation.

Abstract

Three catenas comprising of ten soil profiles on different physiographic positions were investigated. The paper deals with the physical and chemical characteristics of the soils. It is observed that in the foot slope of the catena' the soils are dominated by the illuvial materials transported from the higher one. Down the slopes the soils are deeper' heavy in texture with more developed pedogenic process. All the soils have been classified upto subgroup level according to the Taxonomic system of classification.

Abstract

Three catenas comprising of ten soil profiles on different physiographic position were taken for this investigation. This paper deals with only morphological studies (Part I) and physico-chemical and mineralogical studies of soils will follow in later part (Part II). The soils are related to the elements of landscape and the sequence represents as a topodrainage sequence. Microclimate, water table, vegetation, erosion-deposition or a combination of these influence the genesis of soils, fully defining the concept of a Catena. The evidence of desilication from morphological studies reveals that these soils have under gone the process of laterisation. Ten soil profiles of the three catenas were classified according to Soil Taxonomy. All the soils have been classed under Alfisol except in the case of the upland and midland profiles of Catena A and the upland profile of Catena C which may be placed under Entisol.

Abstract

The distribution of different forms of iron in thirty two surface soils of West Bengal was studied. The results showed that of all the forms, free iron in the form of oxide was the highest and exchangeable iron the least. The iron in most cases was preset as on-clay fraction as was evidenced from the fact that exchangeable, available and 0.1 (N) HCl soluble iron bear significant positive correlation with organic carbon.

Abstract

The carbon stored in above ground and below ground biomass of Tectona grandis(Linn. f.) planted in different years in the foot hill region of Darjeeling district, West Bengal was measured. In general, above ground biomass contributed 82 per cent of the total biomass and below ground (ischolar_main biomass) contributed only 18 per cent. Litter biomass varied from 1.36 to 1.60 t/ha. The total biomass carbon pool varied from 57.36 to 135.99 tC/ha. The maximum pool was in the plant of 47 years and minimum when the plantation age was 18 years. The average soil organic carbon stock up to 90 cm soil depth was 188.80 tC/ha and up to 60 cm soil depth was 163.55 tC/ha. The ratio between SOC and biomass carbon varied between 1.82 and 2.31.

Abstract

Carbon stock in soils results from the balance between inputs and outputs of carbon within the below ground environment and the amount of soil organic carbon and its rate of decomposition varies with temperature and precipitation. Altitude is often included in the studies of climate variables on soil organic carbon dynamics. Present study was undertaken to assess the soil organic carbon stock along an altitudinal gradient from 155 to 3500 m amsl in Darjeeling Himalayan region only under foliage cover. Maximum soil organic carbon in the top soil layer (0 - 15cm) was exhibited by sub-alpine/alpine and high altitude (2500 - 3500m and 2000 - 2500m respectively) forest sites (59.8 and 58.2 g/kg respectively) followed by mid-altitude (1500 - 2000 m) forest sites (46.1 g/kg), lower hill (1000 - 1500m) forest sites (40.3 g/kg) and low altitude (500 - 1000 m) forest site (35.8 g/kg). In the Tarai region (<500m), the value was still less (26.9 g/kg). A decreasing trend in soil organic carbon was observed with increased soil depth.
