Thusitha Nandana Jasing Arachchi; Arunee Promkhambut; Anan Polthanee.
The objectives of the research were to identify seed management practices of the combined-system paddy seed producers as well as to examine the contribution and quality of the combined paddy seed supply system compared with the formal and informal systems. The study was carried out in Udaberagama village of Hambantota district in southern province of Sri Lanka during March to June in 2013. Eighty farmers were randomly selected and categorized based on use of paddy seed systems as belonging to either the formal, informal or combined system. A farm interview survey and seed sampling for quality testing were conducted for each farmer. The farmers’ combined system seed production, involved strategies of both formal and informal sector, they use formal sector...

Using hermetic storage method for preserving of rice seed, Phitsanulok 2 variety, in five storage packaging types; plastic bag, LDPE, Nylon, PET12 and Super bag. The experiment aimed to investigate the effect of hermetic storage method with several packaging types on rice seed quality. The split plot in RCB design was used, the main plot were 8% and 10% seed moisture contents while the sub plot were month of storage, for 24 months. Rice seed was contained in five storage packaging types with 5 and 20 kilogram during July 2012-July 2014 at Chiang Rai Rice Research Center warehouse. The result showed that seed stored at 8% and 10% moisture contents contained 5 and 20 kilogram of rice seed in four packaging could maintain rice seed quality follow the seed...

การเร่งอายุเมล็ดพันธุ์ข้าว พันธุ์ กข14 เพื่อประเมินอายุการเก็บรักษาในเขตภาคเหนือ Thai Agricultural
Yawvaluck Gunyamee; Anchalee Prasertsak.
Present study was conducted to evaluate RD14 seed accelerated aging for longevity in humid tropic at Phrae Rice Research Center. Rice seeds from wet season, 2012 were stored in plastic bags at room temperature and were monitored for seed quality every month. Moreover, the rice seed samples were aliquoted for Accelerated Againg Test (AA) with 100% relative humidity and the temperature condition was varied from 44 46 and 48 0c for 72 96 120 and 144 hrs, respectively. The results revealed the correlation between seed germination from each temperature and time accelerated aging and seed stored in plastic bags at room temperature. It was shown that RD14 seed at moisture content 13% in plastic bag could be stored for 6 months with more than 80 % germination....

การเร่งอายุเมล็ดพันธุ์ข้าวเพื่อประเมินอายุการเก็บรักษาในเขตร้อนชื้น Thai Agricultural
Marisa Songkrairat; Anchalee Prasertsak.
Rice seed accelerated aging for longevity evaluation in humid tropic was conducted in order to study the temperature and optimum duration for evaluation of seed longivity at Krabi Rice Research Center during 2012-2013. Rice seeds from rice planted in both wet and dry seasons were used. By storing the rice seeds in plastic bags at room temperature and every month rice seeds were monitored and quality testing, another part seeds were aged in nearly 100 percent relative humidity at 40, 42, 44 and 46 0C for 24, 48, 72 and 96 hours. Seed germination from each temperature and time accelerated aging was correlated to seed stored in plastic bags at room temperature. The result showed that rice seed at moisture content below 12 percent in plastic bag could be...

การใช้ประโยชน์พันธุกรรมข้าวพื้นเมืองสำหรับเลี้ยงไก่ชน Thai Agricultural
Rattapong Meekun; Paitoon Nandang; Kid Nguanmuai; Narong Titinanritthikul.
Paddy riceused as a major source of carbohydrates in the fighting cocks feed. The fighting cocks has been fed widely and also many species have been developed. Some of them have high millions Baht. Fighting cocks breeders need effective rice. We conducted a survey of the needs and characteristics of local rice varieties that can be used as fighting cocks feed. Beginning with a survey from December 2013 to February 2014 the samples were 53 of Fighting cocks breeders in Mae Hong Son province. In a result, it was found that most of respondents were male. Age range was between 28 - 78 years old. The experience of fighting cocks breeding was 5 - 60 years. They raised 4-80 fighting cocks. Demand for rice was 6,881 kilograms per month. Price of rice was 11 - 17...

การใช้เม็ดดูดความชื้นซีโอไลท์ในการลดความชื้นของเมล็ดพันธุ์ข้าว Thai Agricultural
Porntip Thavong; Suwat Saimaya; Adoul Intaraprasert.
Seed drying to suitable moisture content during harvesting immediately and storage is a key factor to maintain a long-shelf life. The purpose of this research was to use the zeolite drying beads to dry rice seeds var. Phitsanulok 2 (PSL2) and Ayutthaya 1 (AYT1) to target moisture content at 6 % and 12 %. Three experiments were carried out at Prachinburi Rice Research Center during April 2012- January 2013. Rice seeds with the different initial moisture content were blended with three beads to seed ratios at 30oC, 40oC and ambient temperature. The results revealed that rice seed moisture content could be reduced to the target moisture content which depended on variety, initial moisture content, the bead-to-seed ratio, drying temperature and drying...

ศักยภาพของเม็ดดูดความชื้นซีโอไลท์ในการลดความชื้นของเมล็ดพันธุ์ข้าว Thai Agricultural
Porntip Thavong; Suwat Saimaya; Adul Intraprasert.
Seed drying, reducing seed moisture content after harvesting and before seed storage is a key factor to maintain a long-shelf life. The viability of rice seeds can be maintained for 5-10 years at ambient temperature if they are stored in a moisture- and air-proof container with seed moisture content of 4-6%. The purpose of this research was to study the potential of zeolite drying beads to dry rice seeds to 6 % seed moisture content. Two experiments were carried out by blending the drying beads with rice seed var. Pitsanuloke 2at three different bead to seed ratios, three drying temperatures (30 o C, ambient temp. and 40 0C ) and four drying periods (12, 24, 36 and 48 hours). The results revealed that rice seed moisture content could be reduced to 3.2 %...

อิทธิพลของการใช้สารเคมีป้องกันกำจัดโรคไหม้คอรวงในแปลงผลิตเมล็ดพันธุ์ขาวดอกมะลิ 105 Thai Agricultural
Teerawat Suwannual; Jumrat Sunyo.
Studies was conducted to determine the effects of fungicide usage on rice blast disease, caused by Pyricularia grisea (Cooke) Sacc. [= Magnaporthe grisea (Hebert) Barr] on rice cultivar KDML105 in Mae Hong Son Province. The four fungicides usage were isoprothiolane (Fuji one) tricyclazol (Beam 75%wp) Azoxystrobin + Difenoconazole (Ortiva 32 SC and Carbendazim (Cardazin-F). The results showed the four fungicides were use in rice KDML105 to be more effective in suppressing blast and protecting yield, compared to control (non-treat). The fungicides that Azoxystrobin + Difenoconazole was moderately resistant to leaf and neck blast, with the lowest percentage unfilled grains per panicle and have highest yield (669 kg/rai) with compare to the other.

อิทธิพลของสภาพแวดล้อมต่อความแปรปรวนของลักษณะประจำพันธุ์ข้าวไม่ไวต่อช่วงแสง Thai Agricultural
Charun Khawhnuna; Anchalee Prasertsak.
Research was conducted in order to study the environmental effects on characteristic variation in the photoperiod sensitive rice varieties at Nakhon Si Thammarat Rice Research Center during 2011-2013. Rice varieties in the study were included Pathum Thani 1, Phitsanulok 2, RD31 and RD41. Results showed that rice grown in April having plant height, number of tillers per hill, number of panicles per hill and panicle length more than rice grown in January and July. The number of filled grains and yields were highest when grew in January. Rice grown in April had high percentage of unfilled grains. The influence of other climatic conditions did not show obviously effect on the growth of rice varieties in the study.
