Combining ability test of eight F5 gherkin lines from 5 generations in selected pedigree method 28 direct and 28 reciprocal crosses was performed. The objective of this study was to selected high general combining ability line and high specific combining ability hybrid for commercial variety. The experiment was designed in RCB with 2 blocks. The trial was planted during July to September 2012 at Lampang Agricultural Research and Training Centre Lampang province. Data were analyzed using Griffing method 1 with fixed treatment effect. The results were significant between varietal in all traits except yield and fruit per plant. General combining ability (GCA) was significant in all traits. Specific combining ability (SCA) was significant in all traits except yield and fruit per plant. Significance was also found in reciprocal effect in all traits except the width of fruit. For the yield of lines P1 P3 P2 P5 and P8 expressed high GCA and six hybrids were P5 / P3 P5 / P2 P1 / P5 P6 / P2 P3 / P2 and P6 / P8 had high SCA.

The Applicability of the Royal Sufficiency Economy Principles to Community Enterprises Management in Surin. The objective was the possibility of applying the Royal Sufficiency Economy Principles. And compare investigate the possibility of applying the Royal Sufficiency Economy Principles. The sample is 316 firm from Community Enterprises in Surin is 1440 firm. The research found that Most of business was industry enterprise. Has capital an average of ฿146606 from private and relatives. The size of the enterprise community (NAV) of less than one million employs up to 10 people with qualifications below bachelor degree have annual sales of less than 2 million settlement enterprise in their local distributor. And supply of raw materials and equipment used in the production of their own local. The possibility of the application the Royal Sufficiency Economy Principles there is at a high level. And Compared to the possibility of applying found that communities that are difference characteristic there is a possibility of the application no difference on the 0.05 significance level.

The objective of this research was to determine the optimal ratio of beetroot pulp to produce American muffin. The experimental arrangement in CRD was used to study the effect of ratio of beetroot pulp at 0 % 5% 10% and 15% of total weight on the quality of product. As beetroot pulp increase L* and b* of sample decreased were observed (p<0.05) while beetroot pulp decrease a* of sample increased were observed (p<0.05). For textural properties higher in beetroot pulp added showed notably decreased in hardness and cohesiveness (p<0.05) and increased in springiness (p<0.05). At 10% of beetroot pulp to produce American muffin by 9-point hedonic composed of 26.66 % moisture 24.63 % protein 11.43 % lipid 1.40 % ash 0.92 % crude fiber 1.34 % insoluble dietary fiber and 55.88 % total carbohydrate 344.91 Kcal. of total energy 102.87 Kcal. of energy from fat and increase of anthocyanin 0.37 %.

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.

Arachis glabata is new variety forage which tolerates drought and provide high protein.This kind of plant is suitable as dairy cow diet. The research was divided into 2 experiments Experiment 1 was conducted to study on nutritive value of Arachis glabata.The experimental design was Randomized Completely Block Design (RCBD) experiment with three treatments. Each treatment consisted of three blocks (three crops) and followed different three variety of Arachis glabata as Cv. Florigraze Cv. Arbook and Cv. Ecotart. Results showed that three variety of Arachis glabata were 28.26-30.75 % of dry matter (P>0.05). In addition Arachis glabata Cv. Arbook was grater 19.78 % of protein than other group of Arachis glabata (P<0.01). Furthermore Arachis glabata Cv. Florigraze was grater 17.63 of hemicelluloses and 3830.00 kcal/kg of gross energy significant different among other group of Arachis glabata (P<0.05). Experiment 2 was conducted to study on ruminal degradability of Arachis glabata using In situ technique in dairy cattle. The experimental design was Randomized Completely Block Design (RCBD) experiment with three treatments. Each treatment consisted of three blocks (three ruminally fistulated dairy cattle) and followed different three variety of Arachis glabata as Cv. Florigraze Cv. Arbook and Cv. Ecotart. Results showed that Arachis glabata Cv. Florigraze and Arachis glabata Cv. Arbook was grater dry matter organic matter and protein degradability at 0-4 hour and 24-28 hour than Arachis glabata Cv Ecotart (P<0.05). In addition kinetic of degradation (a b c and p) of dry matter organic matter and protein were not significant different (P>0.05) among three variety of Arachis glabata.
