Keywords: Canola seed, variety, physical properties, moisture content and sphericity
Abstract: Knowing the physical properties of canola are necessary for designing of equipments for handling, transporting, processing and storage this crop. In this article some of physical properties of canola have been determined and evaluated. Eight varieties were tested at 5 levels of moisture content (W.b) have been used to determine parameters: Axial dimensions, geometric mean diameter, area, projected area, volume, sphericity and aspect ratio. Analysis of variance test of the data showed that, variety significantly affected all parameters (P<0/01) and moisture content only had significant effect on sphericity and aspect ratio (p<0/05). Relationship between the physical properties and moisture content are expressed by regression relations. Comparison of means with Dunkan ' s method showed that PF, Hyola 401 and SIM 046 varieties have the least dimensional differences and the most coefficient of spheicity. RGS 003, Talaye and Okapy varieties have the most dimensional differences and the least coefficient of spheicity.

Abstract: Musi river water finds its use as irrigation source for vegetables and grasses grown in and around Hyderabad city. River water these days has been polluted with heavy load of industrial pollutants and sewage which contains heavy metals. Possibility exists for the entry of heavy metals into food chain. Eleven locations were chosen for the study which represented discharge points and these points were spatially represented using GIS tools. Among the micronutrients studied, Iron and Manganese were high and beyond the permissible limit in water, soil and plant samples. Water and soil in upstream locations, and paragrass samples at all locations contained heavy metal Pb in more than the permissible limit. In addition, Cd content in water (0.01 -0.03 mg L-1 and paragrass (3.47 - 4.70 mg L-1 in all locations and in soils at two locations (0.66-3.11 mg L-1) was beyond permissible limit. Water being the primary carrier, it is recommended to treat water before its use for irregation purposes.

Abstract: Survival, growth and symbiotic performance of rhizobia isolated from saline soil in Tamil Nadu. 30 isolates out of 43 Arachis hypogea plants were obtained and 22 strains were characterized. Majority of the strains of the bacteria do not survive in the high salt concentration of 500 mM Nacl however 350 mM Nacl all the strains were survived in the soil. Inorder to investigate the ability of salt stress on the Rhizobium-Arachis hypogea Symbiosis. At the Rhizobium level, Rhizobium leguminosarum was found for their salt tolerance up to 350mM Nacl. The nodule number, nodule weight, plant shoot and root were moderately affected by mild levels of Nacl (25mM and 50mM). Rhizobia were found to possess greater tolerance for salinity than their host legumes.

Abstract: Eight chilli genotypes-six resistant (PP 965-01-601, VC 16 A, VC 41 A, VC 211A, VC 246 A) and two susceptible (Local selection I and Local selection II) showing variable degree of resistance to cucumber mosaic virus which caused chilli mosaic were evaluated for moisture percentage, membrane permeability and some non-enzymatic antioxidants viz total phenols, flavonoids, ascorbic acid and ? tocopherol at two stages of plant development i.e. nursery stage (before the onset of disease) and flowering stage (after the onset of disease). Moisture content, total phenols, flavonoids, ascorbic acid and ? tocopherol were significantly higer in resistant as compared to susceptible genotypes whereas membrane permeability depicting electrolyte leakage was more in susceptible genotypes. The infected leaves of susceptible genotypes exhibited further decline in all the parameters except electrolyte leakage which recorded increase after pathogenesis. Higher levels of antioxidants are therefore useful in imparting resistance to chilli genotypes against cucumber mosaic virus. They can also be useful as markers in screening of large population of chilli genotypes for their resistance to CMV before the onset of disease.

Abstract: Water is elixer of life. Water makes up more than two thirds of the weight of the human body. It is important to the mechanics of the human body. People can survive days, weeks or months without food, but only about four days without water. There has been a serious concern over the quality of water resources. The World Health Organization (WHO) estimates that 80% of all sickness in the world is attributable to unsafe water. Water may get impurities of various kinds from ground or soil with which it comes into contact it may also get contaminated with sewage and industrial wastes. The quality of water can be determined by detecting its physico-chemical properties. The present study involves ground water analysis of selected regions of Ajmer city. Samples were taken from hand pumps situated in 18 different localities adjacent to Loco & Carriage Workshops of the city, mainly used for drinking purpose. Loco & Carriage Workshops are the oldest workshops of Indian Railways. At presetn complete maintenance work for diesel locomotives, coaches and wagons is carried out in these workshops. About 9500 workers are employed in these workshops. The area around the workshops is also densely populated. Several physico-chemical parameters including pH, electrical conductivity, total hardness, salinity, chloride, sulphate, nitrate, sodium and fluoride were studied. The study indicates slight alkaline nature of ground water samples. TDS and total hardness values were observed higher than permissible limit. While sulphate and nitrate values were observed within the permissible limits as prescribed by WHO. The correlation coefficient showed significant relationship of pH with TDS, calcium hardness and sodium, potassium and fluoride concentration in ground water. EC shows significant effect on TDS, Stastistical analysis also reveals significant effect of chloride content on alkalinity of ground water and that of Mg on hardness of water whereas chlorides shows a postive significant relationship with sulphate and sodium with potassium content in ground water. Except some selected sites, ground water is grossly suitable for domestic purposes.

Abstract: The pathogenic microorganism initially in raw material is seen destroyed on frying in oil. On storage upto six months, the bacterial qualities of both fish pickles have been good. Dhoma pickle has remained in acceptable condition throughout the period of storage. The mackerel pickle developed a dark colour at the top layer and rancid flavour in the sixth month. The higher fat content might have contributed to the poor shelf life of Mackerel pickle. The pickle prepared from Mackerel and Dhoma were acceptable for human consumption upto six month organoleptically and microbiologically.

Abstract: The study conducted during 2002-04 in a grassland ecosystem (Banni grassland, lies between latitude of 23o191 to 23o521 N and east longitude of 68o561 to 70o321 , covers an area of 2900 km2 is a part of Kachchh district ) revealed the presence of 17 grasshoppers species which were active from July to March with peak period of activity in the month of December. No species was observed from April to June. Among the different species, Phlaeoba cinctalis and Recognizable Taxonomic Unit (RTU-unidentified specimen) were most dominant.The activity of the species viz., Chrotogonus oxypterus, Sphingonotus savignyi, Heteracris pulchra and Acrotylus sp. were very meager. The seasonal abundance mainly depends on the prevailing weather conditions. The rainfall and maximum temperature had a negative effect on abundance (non-significant). In general, the incidence of grasshoppers started after the onset of monsoon and the insufficient and delayed monsoon greatly hampered the emergence and abundance of the most grasshopper species. The total grasshopper population irrespective of species was at a higher level, during late monsoon period i.e. October to January matching with the plenty of food material. Thus, temperature and rainfall as individual weather factor did not exert significant influence on abundance of grasshoppers directly, but relative humidity, which is a result of both of these factors, showed a significant positive correlation. Hence, from the present study, it can be stated that the rainfall and rainy days play a key role in abundance, as these parameters indirectly helped in the availability of food and has a delayed effect on population.

Abstract: The present study was carried out for the antimicrobial activity of certain toxic plants. The leaves of four toxic plant species such as Cliestanthus collirnus, Nerium indicum, Strychnos nuxvomica and Parthenia histopora were collected, shaded, dried and powdered. Plant extracts were extracted with different solvent like petroleum ether and acetone by using soxlet apparatus. Four pathogenic bacteria such as Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeriginosa and Klebsiella sp. were maintained by subculture methods. The solvent extracts (petroleum ether and acetone) of the four potential plants were studied for their antimicrobial activity using Kirby - bauar disc diffusion, plate dilution technique and spread technique. Among the selected four plants acetone extracts against the pathogen of Strychnos nuxvomica was found to be much more resistance with the zone inhibition. Among the three concentrations 1000, 500 and 250 ppm of Strychnos nuxvomica was found to be highly inhibitory on the pathogen Staphylococcus aureus.

Abstract: Blood plasma cortisol concentration is an indicator of stress in fish and stress suppressors may serve to ameliorate stress and reduce the cortisol response. Plasma cortisol was evaluated in Common carp, Cyprinus carpio after applying thermal stress and treatment were carried out with a herbal stress suppressor (Stresroak) through immersion and feed in different concentration. Fishes in all stresroak treatment had showed lower cortisol levels than untreated controls. Stresroak shows a significant stress relieving effect at the 2g/kg of feed and 20 mg/L of stresroak immersion. Hence Stresroak can be recommended as a potent stress reliever in aquaculture. Therefore the use of such stress suppressor especially stresroak should be beneficial in reducing thermal stress. Based on our data further studies refining the use of herbal stress suppressor are warranted in common carps.

Abstract: A study on floral phenology, foraging behaviour of pollinators, breeding system and post pollination events of Imaptiens campanulata Wight, of the family Balsaminaceae has been made. The flowering phase is extended up to 180 days and the pollen-ovule ratio calculated as 2026:1. Flowers offer pollen and nectar to the visitors, which include honeybee, Trigona sp., hawk moths and butterflies. It chiefly reproduced by means of cross-pollination where the fruit production was only 30%. Manual pollinations showed that the species permits geitonogamous and xenogamous pollination. The percentage of fruit-set in manually pollinated flowers is higher than that resulting from open-pollination, which indicates that some external agents are required for successful pollination. The seed germination was limited to 10%, which may be one of the reasons for its restricted distribution.

Abstract: About 10000 indigenous rice cultivars are available in northeastern India and nearly 9000 rice germplasm accessions have been collected since 1955. During the present exploration 397 accessions were collected. Evaluation and characterization of these accessions revealed greater variability in leaf characters, maturity traits and plant height. The desirable traits viz., well exserted panicle, higher leaf area, early as well as late maturing, dwarfism, aroma and biotic and abiotic stress tolerance were present in the rice cultivars and their wild relatives. They may be utilized in crop improvement programmes like ideotype, heterosis and genetic engineering to develop qualities in rice suitable for organic farming and sustainable agriculture.
