The usage of wastewater from swine farm for agriculture have study on the production of three plants such as shallot (Allium ascalonicum L.) marigold (Tagetes erecta L.) and ruzi grass (Bachiaria ruziziensis). The experiment was focusing on the growth production and metals accumulation (Pb Cu Fe Zn) in plant. The results shown that swine farm wastewater were a lot of organic substant and nutrient. The biological oxygen demand and chemical oxygen demand were out of standard. The heavy metals lead zinc copper and iron were amount 0.106 0.218 0.082 และ 0.866 mg/kg respectively. The productivity of shallot and ruzi grass were high growing that treated by swine farm wastewater. The marigold production (flower size dry weight and fresh weight) treated by swine farm wastewater found that were not significant from the marigold production that treated by control water. The amount of lead in shallot ruzi grass and marigold flower were out of standard. The shallot and ruzi root found the amount of zinc out of standard. The amount of copper and iron were not out of standard all three plant.

Objectives of this research are to select concentrated Thai fragrance formula for evaluation by sensory test and quality test using Thai Community Products standard for fragrance and to study consumers’ acceptance. This experimental research used 2 groups of population: 25 specialists and 300 personnel of Rajamangala University of Technology PhraNakhon. Methods used for analysis in this research were sensory test products standard test and questionnaires. Statistical analysis included Percentage Mean and Standard Deviation. Results found Thai fragrance formula 2 received the highest satisfaction when compared with formula 1 3. The evaporation method got higher satisfaction than dried powder method both before and after mixing with water. Overall satisfaction of dissolving 50 g of products in 600 ml of water had the best satisfaction level. The product passed the standard test at very good level Most respondents were female with Bachelor’s degree with civil servant career. The product which had been diluted with water received better acceptance in all aspects than the product which had not been diluted with water. Satisfaction in concentrated Thai fragrance formula had high score because it was easy to use and keep If this product was sold. Most respondents thought that Thai perfume can be used in all Thai ceremonies at the best price of 30 Bath.

The relativity of the Downy Mildew (45 and 60 days after transplanting) for 109 lines in both yield and yield components of cucumber from July 2012 to March 2013 was studied at Agricultural Technology Research Institute of Rajamangala University of Technology Lanna Lampang. It is discovered that the correlation coefficient of downy mildew levels at 45 and 60 days after transplanting correlated well at 0.78 (r = 0.73). Furthermore it is also found out that the correlation coefficient of downy mildew levels at 60 days after transplanting was negatively correlated with fresh yield per rai at 0.58 (r = -0.58). When considering from the path coefficient it is found that the number of fruits per plant had high total effects and direct influence on yields per rai (0.84 and 0.70 respectively). Whereas the downy mildew levels at 60 days after transplanting had negative total effects at -0.58 indirectly with number of fruits per plant at -0.27. Thus the cucumber with high downy mildew at 60 days after transplanting will lead to 58 percent of yield reduction that it will reduce the number of fruits per plant which caused yields reduction.

The aim of this research was to study the influence of sucrose on the degradation of anthocyanins in makiang jam. Makiang flesh was prepared by three different methods. In the first method makiang flesh was mixed with sucrose at three different raitos (2:1 3:1 and 4:1) in the second method makiang flesh was soaked in sucrose solution (35 Brix) at three different ratios (1:1 1:1.5 and 1:2) and in the last method makiang flesh was prepared without addition of sucrose. After the jam processing makiang jams were stored at two different temperatures (the ambient temperature and 40 C) for 30 days to measure the degradation of anthocyanins. The results showed that the anthocyanins content in makiang jam decreased with increasing the storage time. The degradation of anthocyanins in makiang jam prepared by makiang flesh without addition of sucrose was higher than those prepared by mixing makiang flesh with sucrose or soaking makiang flesh in sucrose solution. Mixing makiang flesh with sucrose had lower anthocyanins degradation than soaking makiang flesh in sucrose solution. Makiang jam stored at the ambient temperature had lower anthocyanins degradation compared to those stored at 40 C.

The aims of this study were to investigate the effects of ginger (Zingiber officinale Roscoe.) extract on chemical compositions blood glucose levels body weight blood serum insulin levels and lipid profiles in diabetic rats. The experiments were designed to feed orally of ginger extract at a dose 250 mg/kg body weight in streptozotocin-induced diabetic rats for five weeks. The results revealed that the ginger extract significantly reduced blood glucose level lowered serum total cholesterol LDL and raised HDL blood serum insulin in diabetic rats or diabetic rat fed cheese closed to the normal controls and glibenclamide treated rats. These finding indicated that the ginger extract could be remedy as anti-diabetic agent and ginger health care. Because both normal rats diabetic rats and diabetic fed cheese rats receiving ginger extract weight higher than the control rats was statistically significant (p<0.05).
