The yield parameters and cost economics of Withania somnifera were studied using Integrated Nutrient Management (INM) treatments. Withania somnifera is cultivated in around 10,780 ha with a production of 8429 tones in India. The annual demand of this herb increased from 7028 tones (2001-2002) to 9127 tones (2004-2005). The field experiment was conducted at the research farm of Department of Plant Physiology, College of Agriculture, Jabalpur during k.arif season of 2008-2009 (1st year) and 2009-2010 (2nd year), whereas the laboratory work.was carried out in Quality Laboratory, College of Agriculture, Jabalpur. The soil of experimental field was sandy loam in texture with pH 7.5, EC 0.18 dsm-1 having good drainage. Soil analysis revealed that available nitrogen was low (202.0 k.·ha-1) whereas available phosphorus (16.25 k.·ha-1) and potassium (236.0 k.·ha-1) were in the medium range. The present paper shows how to determine the economics of varying INM treatments. Cultivation of W. somnifera in India is gaining popularity among farmers;however, due to poor soil fertility, and costly chemical fertilizers and pesticides its production is not economical or profitable.

Several mechanisms are developed by the microorganisms to tolerate few high concentrations of heavy metals. One of these mechanisms dependent upon anabolic and catabolic energy of microorganisms is the bioaccumulation of heavy metals. In present work. approximately four varieties of bacteria have been isolated from the ash dyk. sample of four thermal power plants of Chhattisgarh, i.e., Bharat Aluminium Company (BALCO), Chhattisgarh State Electricity Board (CSEB), k.rba, Thermal Power Cooperation (NTPC), Bilaspur and k.k.Ak.ltara, Chattisgarh. Out of one hundred fifty isolates, three were capable to grow in varying concentration of heavy metals. The strains were tested for their tolerance against six different types of heavy metals dominant in the ash samples viz. Pb, Hg, Ni, Co, Cu, Mn. Their maximum resistance existed up to 0.6mM/ml of the above mentioned different metals under lab standard conditions. Three isolates are found suitable for the multiple metal resistance ability viz SM2, SM3, and SM12. These are categorized as Bacillus cereus (SM2, SM3), and Bacillus subtilis (SM12) after performing 16S rDNA sequencing.

The present study reported on phytoplank.on in comparison to the zooplank.on in Limha Pond, Ghutk., Bilaspur. The phytoplank.on represented in larger number of Cyanophyceae with least density of Dinophyceae and Chlorophyceac, and Bacillariophyceae is the second dominant group. The present study tried to discuss on the problem Macrobenthic fauna of Limha Pond, Ghutk. Bilaspur and observed quantitative algal and faunal diversity i.e. phytoplank.on (34 species), aquatic organism (6 species) Bacillariophyceae (8 species), Chlorophyceae (11 species), Euglenophyceae (6 species), Zooplank.on (20 species), and Fish species (16 species). Present study revealed that Cyprinidae (carps) were the dominant fish and Catla was a major contributor among carps. The following species Catla catla, Labeo rohita, Cirrhinus mrigala, Labeo calbasu, Barbus tor and Cirrhinus reba etc. were noted in Limha pond, Ghutk., Bilaspur.

In present study invasion of Parthenium hysterophorus L. and its impacts on agriculture fields will be done in different cultivated crops in Bilaspur. The present work.deals with diversity and distribution of weeds species in cultivated fields of Bilaspur C.G. A total number of 28 species under 27 genera and 16 families was distributed in three study sites (k.ni, Sak.i & k.ta) of cultivated fields in Bilaspur C.G. These study sites were located in different altitudinal zones responding different conditions in the this study. The number of species per sites ranged from 13 to 24. In the Sak.i, number of species was ranged from 17 to 27, and the relative density of plant species ranged between 0.77 (Heteropogon contortus, Solanum surratense, Vernonia cinneria and Leucas aspera) and 22.92 (Parthenium hysterophorus). In the k.ta, number of species was ranged from 14 to 28, and the relative density of plant species ranged between 0.85 (Ageratum conyzoides, Heteropogon contortus, Triticum aestivum) and 29.06 (Zea mays) and 30.91 (Parthenium hysterophorus). In the Agriculture field, number of species was ranged from 15 to 28, and the relative density of plant species ranged between 0.58 (Leucas aspera) and 26.23 (Triticum aestivum). Present work.will give the information that weeds are harmful to herbs, crops and medicinal plants. Parthenium weed can suppress and crowd out other weed species, and could form a single dominant population in the invasion area, causing serious threat to plant community biological diversity.

The plant Aloe vera is used in Ayurvedic, Homoeopathic and Allopathic streams of medicine, and not only tribal community but also most of the people for food and medicine. The plant leaves contains numerous vitamins, minerals, enzymes, amino acids, natural sugars and other bioactive compounds with emollient, purgative, anti-microbial, anti inflammatory, antioxidant, aphrodisiac, anti-helmenthic, antifungal, antiseptic and cosmetic values for health care. This plant has potential to cure sunburns, burns and minor cuts, and even sk.n cancer. The external use in cosmetic primarily acts as sk.n healer and prevents injury of epithelial tissues, cures acne and gives a youthful glow to sk.n, also acts as extremely powerful laxative.

The frequency of the Love-type surface waves in a bedded structure con- sisting of a porous piezoelectric (PP) medium and a functionally graded material (FGM) substrate is approximated. The FGM layer is assumed to have a constant initial stress. The Wentzel-k.amers-Brillouin (Wk.) approximation technique is used for the wave solution in the FGM layer, and the method of separation of variables is applied for the solution in the porous piezoelectric medium. The dependence of the wave frequency on the wave number is obtained for both electrically open and short cases. The effects of the gradient coefficient of the FGM layer, the initial stresses (tensile stress and compressive stress), and the width of the FGM layer are mark.d distinctly and shown graphically. The findings may contribute towards the design and optimization of acoustic wave devices.
