Investigate the changes that occur in the placenta tissues of pregnant rats that were administered acrylamide (AA) and vitamin E as a protective agent during pregnancy. Thirty rats that were proven positive for pregnancy with vaginal smear test were randomly distributed into control, corn oil, vitamin E, acrylamide and vitamin E + acrylamide groups. Pregnant rats were decapitated on the 20th day of the experiment. Malondialdehyde (MDA), reduced glutathione (GSH), total antioxidant capacity (TAS), total oxidant capacity (TOS) and Xanthine oxidase (XO) levels were measured in placenta tissues. It was determined that acrylamide application during pregnancy statistically significantly increased MDA, TOS and XO levels and reduced GSH and TAS levels in the placenta tissue of pregnant rats when compared to all other groups, and GAS and TAS levels statistically significantly increased in vitamin E administered group when compared to all other groups and TOS and XO levels were decreased to control group levels. It was observed that orally administered AA changed the antioxidant / oxidant equilibrium favoring the oxidants by increasing MDA, XO and TOS levels in pregnant rats and caused oxidative stress, while vitamin E administration returned the antioxidant / oxidant equilibrium back to normal levels, preventing oxidative stress induced toxicity.

This study was carried out during the summer of 2014 to determine alternative quality forage sources that could be grown in the Aydın ecological conditions. In the study, effects of 3 different mixtures and 2 pure species (100% Buckwheat, 25% Buckwheat -75% Soybean, 50% Buckwheat -5 0% Soybean, 75% Buckwheat - 25% Soybean, 100% Soybean) and 2 different harvesting times (50%-100% flowering/buckwheat) on yield and quality characteristics were investigated. According to measurements, the highest average herbage yield was obtained from 75% Buckwheat-25% Soybean application (3100 kg/da) at 2nd harvest time. When the average of hay yield was examined, the results were similar to herbage yield. When ADF and NDF were examined, the highest values were seen at the 2nd harvest. When the crude protein ratios were examined, it was found that they decreased at the 2nd harvesting time and the highest value was determined at 100% soybean application at the 1st harvesting time (21.08%). When Digestible Dry Matter (DDM) and Relative Feed Value (RFV) were examined, the highest values were determined in 100%Soybean applications at first harvest time and when the mixture applications were examined, the highest values were determined to be 75% Buckwheat - 25% Soybean application. As a result of the study, it was determined that the yields obtained at the 2nd harvest time were higher but the forage quality decreased. When the mixtures were examined, it was determined that the mixture having the highest roughage value was 75% buckwheat + 25% soybean application. In this study, the buckwheat which have short vegetation and good quality and the soybean, which is infront of with high quality, mixtures were examined. It has also been found that these mixtures may be important for obtaining high-quality forage in the short and intermediate periods.

Restoration of soil has been identified as the option; to ensure crop sustainability. However, as per Trophobiosis Theory of French Scientist F. Chaboussou, focus on development of healthy plants is necessary to abate pest and disease invasion so as to ensure sustained crop performance, even under unfavorable environmental conditions. The present study, in randomized block design with green gram as test crop; was undertaken in Krishi Vigyan Kendra (Howrah, West Bengal) to evaluate the effectiveness of Inhana Rational Farming (IRF) Technology towards crop yield and soil quality development under different sustainable models viz. organic cultivation, integrated soil with organic crop management and non- chemical crop management; as compared to conventional farming practice. Highest yield was recorded under organic (933 kg ha-1) followed by integrated (921 kg ha-1) and non- chemical plant management (902 kg ha-1). The results were well corroborated with the plant development index obtained under these treatments. Favorable trend of soil quality under sustainable models especially in terms of microbial properties indicated the role of quality compost towards speedy rejuvenation of soil dynamics. The study indicated that reduction of synthetic fertilizers and qualitative management of soil is essential to restrict yield decline. However, plant management shall be prerequisite for ensuring crop sustainability without any time lag and under the changing climatic patterns. In this respect the potential of IRF Technology has been well accounted.
