Objective of the present study was to investigate influence of transplanting methods, namely, parachute” and wet seeded culture, on growth, i.e., height and tiller number/bunch, incidence of disease outbreak, soil quality and yield of “Hommali 105” rice cultivated organically. Results showed that the transplanting methods played insignificant role on growth as well as the incidence of disease outbreak (p0.05). However, the “parachute” transplanting method led to higher tiller numbers/bunch and rice yield than that obtained with the wet seeded method, 27 against 5 tillers/bunch (p<0.05) and 1.7 folds, respectively. Further, during cultivation, soil qualities in terms of pH and content of organic matter, nitrogen and potassium appeared to be comparable...

สภาพฟ้าอากาศที่เปลี่ยนแปลง: ผลกระทบของอากาศหนาวเย็นต่อผลผลิตของข้าวในเขตภาคเหนือตอนล่าง Thai Agricultural
Acharaporn Na Lampang Noenplab.
Rice growing areas in the Lower North of Thailand has been severely affected by extreme climate change seen as cold injury in 2007 dry season. The total affected area was 621,176 rai (99,388 ha) resulted in a drastic loss of 2,749 million Baht ($US 89 million). Since it has been reported that the most sensitive stage to cool temperature is the young microspore stage, approximately 8.5-10 days before flowering, and the critical range of temperature for cold injury resulted in panicle sterility is 15-20 oC. This preliminary investigation firstly aimed to observe visible changes after exposing to cool temperatures. Secondly, to observe the relationship between low temperature and sterility. Thirdly, to measure a subsequent reduction in grain yield of rice cv....

Rice production potential zoning of Petchaburi province had been conducted from 2010 to 2012. Research methodology composted of general rice production information collection, soil sampling and crop cutting from farmer field, and field experiment. The research found that there were 4 major rice varieties growing in the area Chainat1, Phitsanulok2, Suphanburi60 and Suphanburi1. The field experiments for comparing of fertilizer application were conducted 2 seasons at 12 locations. The results showed that L1 area, recommended fertilizer application (F1) gave the average yield of 1,067 kg/rai, while fertilizer application base on soil analysis (F2) gave the average yield of 1,222 kg/rai. Farmers’ practice of fertilizer application (F3) gave the average yield...

Reciprocation of Queen Sirikit’s commanded to slove a problem rice harvest insufficeint for consumption of farmmers whose live in area of High land Agricultural Development Royal Project, Ban-Nagian, Ampur Omkoi, Chiangmai. The project proceeded for a decade (2548-2557 BE). Project objective is to reach rice varieties which appropriate to condition and consumption in the area lead to acceptance and utilization of the new varieties. Project procedures includes researching each varieties, comparing output, developing varieties that are common in the area into pure line, developing seedstock manufacturing to support “Bank of Royal Rice” activity and found that Ka-Saw (SMGC02001) which is the popular rice variety, in addition to there are 2 predominant...

Three years experiments have been conducted during 2010-2012 to develop and test for rice yield improvement and production cost reduction in Southern part of Thailand. This experiment was conducted in Phatthalung Rice Research Center in the first two years and in farmer field for the third year with Split Plot in RCB; rice varieties as main plots and rice seed rate or spacing as subplots and 4 replications. Results in research center found that for broadcasting rice, Pathum Thani 1 and RD37 which were photoperiod insensitive varieties gave the highest yield when direct broadcasted with 20 kg/rai seed rate whereas photoperiod sensitive varieties such as Chiang Phatthalung and Sangyod Phatthalung showed the highest yield when soak seed broadcasted with 15...

Weeds play an important role in decreasing yield in dry-direct seeded rice. However, using herbicide could effectively control weed and help increase rice yield. The objective of this research was to investigate the effect of herbicide application on weed control and rice yield in dry-direct seeded paddy field. The experiment was conducted at a farmer’s field, Khon Kaen province, from June to November of 2012 with the use of rice variety KDML 105. The nine treatments were 1) no weeding, 2) hand weeding, 3) oxadiazon, 4) oxadiargyl, 5) oxyfluorfen, 6) pendimethalin, 7) butachor/propanil, 8) clomazone and 9) bispyribac-sodium. The rates of herbicide application of treatments 3-9 were 120.0, 40.0, 28.2, 198.0, 175.0, 38.4 and 4.0 g ai/rai, respectively, The...
