Abstract: Rainbow trout is the native of rivers and lakes in the western half of North America. However, it has been transplanted across the world including Kashmir, India. Experiments conducted to study the rearing success of the fish at Dachigam Trout Fish Farm, Laribal, Kashmir, India during 2004-07 revealed that the fish attained tablesize (250 g) within 24 months. Fish were fed with formulated feed (having 40% protein content) at the rate of 4% of body weight daily in spilt doses. Early stages of fish (up to advanced fry) were fed with higher protein content feed (48%) at the rate 8% of the body weight. Eggs were obtained by stripping (dry) and incubated in spring water. The eyed ova stage was reached within 14-20 days of stripping. The hatchlings appeared after another 10-15 days and these accepted artificial feed within another 14-20 days. The fish were reared up to advanced fry stage in spring water and the latter stages in stream water. The spring water at Dachigam showed a temperature range of 10.6-13.8 oC, pH of 7.0-8.0, dissolved oxygen of 7.0 -10.2 mg/L and free carbon dioxide of 0.6-1.7 mg/L, whereas the stream water showed a temperature range of 5.5-15.6oC, pH of 7.2-8.0, dissolved oxygen of 7.7-11.9 mg/L and free carbon dioxide of 0.7-.6 mg/L. The saleable table sized trout showed feed conversion ratio (FCR) of 1.45 to 1.80. Males attained full maturity after 2 years, while females after 3 years.

Abstract: The batch adsorption studies were undertaken to assess the suitability of inexpensive adsorbent prepared from agricultural waste, rice husk. The adsorbent was prepared by chemical impregnation method followed by physical activation. Static studies have aimed for investigation of fluoride removal efficiency under the varying conditions of the major parameters fo adsorption, viz. pH, dose of adsorbent, rate of stirring, contact time and initial adsorbate concentration and optimized by batch procedure in the mixture of known concentration of fluoride solution. The optimum sorbent dose was found to be 10g/L by varying the dose of adsorbent from 0 to 16 g/L; equilibrium was achieved in 120 min for the optimum pH. It has been observed that the optimum adsorption takes place at lower pH by varying pH from 2, 4, 6, 8, 10. Maximum fluoride removal was observed to be 75% at optimum conditions. Freundlich as well as Langmuir isotherms were plotted and constants of isotherms were determined.

Abstract: Electronic waste is presenting a challenge for the new millennium. Almost every business organization, Institution and even educated individuals are using computers and find it essential and inevitable to conduct their day to day business activities. Rapid changes in computer technology have made it difficult for the users to restrict themselves to stick on their old machines, which are becoming obsolete, unwanted and not at all usable after a period of time. This problem of rapid obsolescence has resulted into tremendous growth of electronic waste commonly referred as E-waste. In fact, the accurate estimation of obsolete unwanted and futile computers is not possible but approximation done by the researchers has given an account of such waste material to the tune of 80% of the total computers available in the organizations of Karad, Maharashtra. Such electronic waste which contains various hazardous materials, has created an immense threat to the environment, society and the world as a whole. The E-waste incorporates various toxic metals and chemicals like lead, cadmium, selenium, arsenic, beryllium, lithium, mercury, nickel, chromium, polybrolium, biphenyl chlorofluoro carbons, uranium, zinc sulphate, toner dust, chloride and many more such toxic materials, which are deadly harmful to human health and environment as a whole, if not disposed off carefully. Therefore, it is an evitable and essential requirement to study thoroughly following points in order to have effective E-waste management: 1. To understand gravity of problem created by E-waste 2. To find out the causes and sources of E-waste, 3. To describe health hazard created by E-waste , 4. To determine feasible and viable methodology to manage E-waste and 5. Review of the research and coming out with conclusions and suggestive measures. Thus, the paper presented stresses the significance of E-waste management in the global scenario Karak as an area of study and presents the status of E-waste as on today, suggest measures for arresting the trend of incresing E-waste and managing it effectively.

Abstract: Fly ash is one of the residues generated in combustion of coal. Fly ash is generally captured from the chimneys of power generation facilities. Fly ash includes substantial amounts of silica (SiO2 ), both amorphous and crystalline, and lime (CaO). Fly ash is commonly used to supplement Portland cement in concrete production, where it can bring both technological and economic benefits. Increased awareness of environmental hazards, steep rising prices of building materials, non-availability of space to stock the fly ash and other such factors have generated interest among the researchers to work on the gainful utilization of fly ash as an alternate building material with potential for replacing cement partially in constructions. Fly ash utilization in concrete not only reduces the cost due to cement savings but also contribute to reduced carbon - dioxide emissions contributing to environmental protection. It is well established by now that the concrete structures exposed to acidic environments deteriorated much faster when compared to their counterparts in non-aggressive environments. High-Performance-Concrete (HPC) is a new generation concrete which has the potential to perform well in aggressive environments. This paper presents the details of an experimental investigation planned to utilize fly ash in production of HPC. Acid attack tests have been conducted to measure the durability of HPC. This investigation is undertaken to study and define a better HPC mix containing locally available fly ash which can sustain in chloride and sulphate environments. The investigation examines the progressive deterioration of concrete mixtures containing various combinations of fly ash based HPC mixes exposed to sulphate and chloride solutions.

Keywords: Bambusa vulgaris var. striata, Yellow bamboo, Botanical Garden, rhizome
Abstract: Bambusa vulgaris var. striata Lodd. ex. Lindl., commonly known as ' Yellow bamboo ' is one of the highly ornamental bamboo species. It is native to China and Japan (Tewari, 1992) and is commonly cultivated all over India as an ornamental upto an altitude of 1000m. It is a moderate size bamboo, not densely tufted, culms 8-20m high, 5-10 cm diameter bright yellow, glossy with prominent green stripes, Internodes are upto 45 cm long.
The species has an irregular flowering cycle (Intermast period) of 80 + 8 years (Banik, 1995). Flowering of this species has not occurred in many parts of the world. However, it was reported in Sri Lanka and Botanical Garden, Calcutta, India. Recently , John and Nadguada (1997) reported flowering of Bambusa vulgaris in India.
Due to long inter-seeding intervals, the propagation of this and most of the bamboo species is done vegetatively by offset and rhizome planting, however the availability of these propagules is very limited and cannot be applied for large scale plantings. Besides, these propagules are bulky, difficult to extract, transport and expensive.
Propagation through culm cuttings is the most feasible and advantageous method over traditional methods. A few traditional cuttings can be obtained per clump each year while several hundred 1-2 nodal culm cuttings can be extracted throughout the year without affecting the clump productivity or disturbing the rhizome system. Medina et al. (1962) propagated B.vulgaris var. vittata through culm cuttings. The role of growth regulators for induction of rooting has been observed in many bamboo species (Seethalakshmi et al., 1983; Surendran et al., 1983; Kumar et al., 1988). In the present study efforts have been made to propagate Bambusa vulgaris var. striata through culm branch cuttings using various growth promoting substances.

Keywords: Mine spoils, erosion, dry tropical environment
Abstract: Mining activity results in huge dumps of overburden materials as mine spoils. These mine spoils are drastically disturbed, nutritionally and microbiologically impoverished habitats (Singh and Jha, 1993). Mine spoils need to be stabilised to prevent erosion and contamination of rivers and adjacent agricultural lands from harmful leachates. Natural restoration of mine spoils is a slow process, but it can be accelerated by planting native tree species. This vegetative cover not only stabilises the spoil but increases the biological fertility and diversity of the mine spoils. The objective of the present study is to evaluate the effect of structural characteristics of mine spoils on growth performance of planted native tree species in a dry tropical environment.

Keywords: Piper longum,Pipul, Pipli,root and stem cuttings
Abstract: Piper longum Linn., commonly known as ' Pipul ' or ' Pipli ' (Long pepper in English), belonging to family Piperaceae is an economically important semi-erect creeper. Indian long pepper is mostly derived from the wild plants, the main sources of supply being Assam, West Bengal, Uttar Pradesh and Uttarkand. It is reported to be cultivated at low elevations in the Annamalai hills in Tamil Nadu and parts of Meghalaya, particularly in the Cherrapunji area. Long pepper is cultivated on a large scale in limestone soil, 450 to 600 m below the Cherrapunji region, which receives very heavy rains from the end of March to the middle of September and where the relative humidity is high. As there is relatively high demand of this spice in domestic market in India, so a large quantity of long pepper is imported by India from countries like Malaysia and Singapore. Pipul or pipli is long associated with the ethnomedicinal history fo Bengal. Relevant data on this has been collected from the folk medicine as practiced in the districts of West Midnapore, Bankura and Purulia in West Bengal. It prefers laterite or red soils in shaded moist conditions. Thus there is ample scope to grow this economically important plant in South West Bengal conditions but no standard method for propagation of Pipul was in practice. In this experiment, germination studies from seeds and vegetative propagation from root and stem cuttings were done in the nurseries of Midnapore, Purulia and Bankura to standardize and promote quick but cost effective propagation technique for Pipul. This article also presents various ethno medical uses of Pipul as practiced in the districts of South Bengal.

Abstract: During study on vegetation diversity, 88 species of grasses and herbs were identified in 2005 and 2006 at Bara Nandara kho, Banswara (Rajasthan). Out of these, 14 species recorded as new arrival in the areas, when compared with the other existing literature of the region. These species are Brachiaria deflexa, Brachiaria setigera, Croton bonplandianum, Cyperus arenarius, Eragrostis aspera, Euphorbia granulata, Indigofera sessiliflora, Justicia prostrata, Justicia simplex, Ocimum canum, Rhynchosia bracteata, Sporobolus nervosus, Stylosanthes fructicosa and Triumfetta rhomboidea. Out of these B.deflexa, B.Setigera and C.arenarius are species of xeric environment; whereas the other species are of semi-arid or dry sub-humid region. Such changes in vegetation composition resulted from invasion of other species are indicative of variations in climated and edaphic conditions in the region.
