Opis:
The changes in some blood biochemical parameters were studied in the freshwater fish N. notopterus under saline exposure for a longer period of 30 days. The blood biochemical parameters are glucose, protein, triglycerides and cholesterol. All these parameters exhibited increased level except of blood glucose which remained unchanged as observed after the termination of saline exposure. Thus it indicates that although fish survives and able to tolerate extreme saline condition as there was no mortality during the exposure period. The increase of blood biochemical parameters can be considered as a kind of saline stress response particularly on lipid derivatives.

Opis:
The research methodology recommended by the OECD (Organization of Economic Co-operation and Development) and ISO (International Organization for Standardization) guidelines for testing of chemicals meets the most criteria expected for ecotoxicological testing except the testing condition and the organic matter. The guidelines were initially developed by temperate countries, with testing conditions as 20 °C and the organic matter as sphagnum peat which is commonly available in those countries. But these two criterions are difficult to be followed in tropical countries. Thus there arises a need of modifying these criterions for toxicity studied in tropical regions. In this study a trial was made for substituting the fermented coir pith for sphagnum peat and the validation of the modified tropical artificial soil (TAS) was done by conducting chronic toxicity studies on Eisenia fetida against an inorganic fertilizer, superphosphate (SP) under tropical condition, i.e., 28 ±2 °C. The performed study showed that the SP determined lower earthworm mortality in TAS comparing to OECD soil for all tested concentration levels. The number of juveniles produced in OECD soil was also significantly reduced (p < 0.05) than in TAS. This may be due to the production of large amount of hydrogen ions when the temperature increases and making the medium acidic. The fermented coir pith was more suitable for ecotoxicity studies under tropical condition than sphagnum peat.

Opis:
The recent experiment was conducted to assess the effect of herbicide (quizalafop-p-ethyl) on growth, photosynthetic pigments, enzymes and yield of Black gram (Vigna mungo L.) during the summer season 2013-2014. This experiment comprised black gram (variety ADT 3) and different concentrations of herbicide (quizalafop-p-ethyl) treatments compared with control. Reduction in growth, photosynthetic pigments, enzymes and yield parameters were observed with 0.5 % herbicide application followed by 1 %, 1.5 % and 2 %, out of all treatments 0.5 % shows least reduction. Thus, 0.5 % herbicide application is the safest way for weed control in Black gram field as it showed least adverse effect on growth, photosynthetic pigments, enzymes and yield of crop when compared with other treatments.
