Abstract:
In present study, a total of 15rhizobial isolates were isolated from the root nodules of Medicagopolymorphagrowing in Jaipur and were characterized for their phenotypic, biochemical and plant growth promoting activities. The root nodules of M. polymorpha were elongated, branched and indeterminate. All isolated rhizobia were highly diverse in their physiological traits. Based on colony morphology, all isolates were categorized into six groups. Major group containing 6 isolates (MP1, MP3, MP9, MP10, MP11 and MP13) showed white, opaque, raised, smooth edges, non-gummy, and mucilaginous characteristics. Four rhizobia strains MP3, MP4, MP9, and MP15 showed salt-tolerance up to 3% and were well adapted to high alkaline conditions and exhibited growth in extremely alkaline media (pH 10). Majority of strains showed positive result for IAA production, nitrate reductase and catalase activity. In addition, citrate utilization, ammonia production, phosphate solubilization and cellulase activity were observed in few isolates. In present study, some rhizobia isolates like MP3, and MP15 were very versatile rhizobia that showed high plant growth promoting activities (IAA production and phosphate solubilization) and were also tolerant to high pH and salt concentration. Such type of superior rhizobia can be part of biofertilizers to enhance legume crop productivity in an ecofriendly manner without application of chemical fertilizers. Our study suggested that rhizobia isolates associated with Medicagopolymorpha were significantly diverse in their physiological and biochemical parameters

Abstract:
Cyanotis ceylanica Hassk. (Commelinaceae) is reported as a new record for the flora of India from Gingee hills, Eastern Ghats of Tamil Nadu. Detailed descriptions of morphological and reproductive characters based on field observation with photographic images are provided for easy identification of this species.

Abstract:
Leaves are most important part of the plant and can be used for the identification of a taxon. An appropriate understanding of leaf development in terms of shape and responsible abiotic factors is necessary for improvement in plant. Leaf shape variation could be evaluated successfully, and the symmetrical and asymmetrical elements of the overall shape variation could be detected. The aim of the present study was to establish a quantitative analysis method of leaf shape by elliptic Fourier descriptors and principal component analysis (EF-PCA). EF-PCA describes an overall shape mathematically by transforming coordinate information concerning its contours into elliptic Fourier descriptors (EFDs) and summarizing the EFDs by principal component analysis. We can be able to extract six variables by using leaf specimen images from field and herbarium specimens. In the present study, total leaf area with respect to notch area is more variable within species. Within a species the major source of the symmetrical elements may be governed by genotypic features and the asymmetrical elements are strongly affected by the environment. We could discuss the value of morphometrics to detect subtle morphological variation which may be undetectable by human eye.

Abstract:
There have been a lot of practical applications of phytoremediation in the last ten years, involving organic, inorganic, heavy metal, and radionuclide remediation. India would find this to be an excellent alternative to conventional remediation methods as it is a sustainable and inexpensive process. The huge retention of industrial waste in soil resulted in soil pollution which is more hazardous due to the long-term persistence of contaminants. A major source of hazardous waste products in Bhopal city is the industrial region. Near residential areas, industries produce pollution that can be very harmful to human health. The objective of this research was to determine which heavy metal accumulators are capable of absorption and translocation of heavy metals. In the Govindpura sampling sites, Cr and Ni concentrations were higher, while Cd concentrations were lower. Phytoremediation was conducted by comparing the heavy metal accumulation of Datura inoxia, Calotropis procera, Ricinus commmunis, and Polygonum in vitro cultures.

Abstract:
An investigation on “Weed Management and Crop Growth Modeling in Soybean” was carry out on red sandy loam soil at UAS, Main Research Station, Hebbal, Bangalore during Rabi 2010 (September to December). The weed control practices included in the study were i) Pendimethalin 30 EC 1.0 kg a.i./ha – 3 days after sowing, ii) Imazethapyr 10 SL 100 g a.i./ha – 20 days after sowing, iii) Quizalofop-p-ethyl 5 EC 50 g a.i./ha – 20 days after sowing, iv) Chlorimuron ethyl 25 WP 6 g a.i./ha – 20 days after sowing, v) Hand weeding (20 & 40 DAS) and vi) un-weeded control. The experiment was designed as RCBD with four replications. Growth models – Richards, Logistic, Cubic polynomial and Quadratic polynomial simulated the course of dry matter production/plant by >97per cent under all weed management practices, indicating that weed competition did not alter the pattern of crop growth, but affected the total production substantially.

Abstract:
The specific term for the Water hyacinth plant is Eichhorniacrassipes. The water plant that flows freely, rising at still or slower water sources. Water Hyacinth develops massive biomass and doubles its population in two weeks by fast-growing. These entail a loss of biodiversity, water pollution, water loss, agriculture, infrastructure damage and negatively effect on public safety, and water species. The objective of the study is to evaluate the chemical composition of water hyacinth ash by XRD and SEM .XRD is an obligatory method for analysing the characteristics and composition of materials. It is a non-destructive method to analyse all types of material substances like powder, crystals, and fluids. Nowadays X-ray diffraction Techniques are utilized in assorted fields like research, development, and production of materials. The particle size, shapes, surface roughness, and fracture are defined using aEDAX. When a sample is placed on the beam and multiple signals determine the interactions with the samples. Acetone is used to stop the hydration reactions. Then the specimen is dried and made to conduct. Finally, a micrograph was recorded using SEM.
