Maize crop is cultivated for the purpose to obtain high production of grains. Term maize is derived from Latin language, meaning life benefactor. Its grains possess high nutritional values. Because of high importance of maize grains, a study was performed according to CRD by three replications to examine the mitigating effects of antioxidants such as citric acid, ascorbic acid and salicylic acid to salt toxicity. Foliar application of these three antioxidants were done at 200 ppm concentration and one treatment as mixture of 100 ppm of all three antioxidants. Data was noted for different growth, physiological and yield attributes. Analysis of data revealed that 100 ppm concentration mixture of all three antioxidants provided highest results for all attributes. The 100 ppm antioxidant mixture foliar application caused 8% increase in plant height and 29% increase in ear length as compared to controlled plants sprayed with water. It also caused significant increase in concentration of all photosynthetic pigments such as Chl a, Chl b and carotenoids. Foliar application with 100 ppm of antioxidant mixture also caused 21% increase in catalase activity and 27% increase in peroxidase activity. This treatments also helped plants to accumulate more potassium and provided lowest (0.44) Na+/K+ ratio. Hundred grain weight was observed highest (44.7) in plants sprayed with 100 ppm of antioxidant mixture. Harvest index of those plants were also highest (45.65). So, from these results it can be assumed that 100 ppm antioxidant mixture foliar application provided highest results followed by 200 ppm concentration of ascorbic acid.

Pesticides are commonly used in agriculture soils to distroy various pathogens. During the late 1950s and early 1960s, the media in Western Europe and North America extensively covered the issue of birds on agricultural land being poisoned by aldrin, dieldrin, and heptachlor, which were commonly used as seed dressings. To highlight this issue, an experiment was performed to examine the effects of sodium fluoride on Japanes quail growth, biochemical and histology of kidney. In the present work, forty-eight sexually male Japanese quail, weighing 105gm, were used, divided in 4 equal groups as A, B, C & D having 12 quails in every group. Quails were acclimatized for two weeks. After acclimatization experimental treatments were applied to their respective groups. Duration of experiment was 30 days. Sodium fluoride was given to quails orally with the help of gavage on daily basis. Quails in group C handled with 3.75mg/kg dose and group D handled with 5.0mg/kg dose showed significant changes in physical, biochemical and renal parameters as compared to control group. These treatments also cause significant reduction in final weight of birds. Birds in groups B with 2.5 mg/kg dose showed non-significant results. On 3.75mg/kg exposure, the highest accretion of fluoride occurred in the kidney. Sodium fluoride exposure significantly increased the kidney injury and other renal biomarkers. The histopathological variations such as necrosis of parenchymal cells, congestion and hemorrhage varied in dose dependent manner of sodium fluoride.
