Somrote Prakobboon; Wannaphan Janlapa.
Low production efficiency and high production costs are the weakness in the SWOT analysis of rice production Thailand. Participatory cost analysis and searching for cost reduction of rice production might strengthen the rice farmers. During 2011 - 2013, we conducted community based pilot trails in the village 5 and 7, Thachang Subdistrict, Muang District, Nakhonnayok Province. After community meeting to identify local rice production problems and selected the pilot field, the field was prepared and planted with pre-germinated seed broadcasting at the rate of 20 kg/ha. Insect and pest were observed daily. At 15 days after planting, 30 kg/ha organic fertilizer and 25 kg/ha chemical fertilizer was applied to the field. Comparing production cost and yield to...

Studies of BPH density from light traps were monitored at Prachinburi Rice Research Center and five different farmer fields in Nakhonnayok Province of the following sites: 1) Moo 1 Tha Sai subdistrict Mueang district 2) Moo 7 Tha Chang subdistrict Mueang district, 3) Moo 5 Srisa Krabue subdistrict Ongkharak district, 4) Moo 1 Bueng San subdistrict Ongkharak district and 5) Moo 12 Ban Phrik subdistrict Ban Na district. To attract and trap the brown planthopper (BPH), light was daily turned on between 6.00 pm to 9.00 pm. Insect collecting and identification were daily monitored from January 2013 to October 2014. The results indicated that the trend of long-winged BPH population density with light trap catched from five different farmer fields in Nakhonnayok...

Light trap is an important tool to forecast and warn of many rice insect pests outbreak. The aim of this research was to find the relationship of BPH density from light traps which collected from Prachin Buri Rice Research Center and rice fields in Nakhon Nayok province. For developing outbreak forecasting system in Nakhon Nayok. Selected locations in Nakhon Nayok were Mueang district (Moo 1, Tha Sai and Moo 7, Tha Chang) Ongkharak district, (Moo 5, Srisa Krabue and Moo 1, Bueng San) and Ban Na district. (Moo 12, Ban Phrik) which daily collected from 6.00 pm to 9.00 pm (January 2013 to October 2014). The results indicated that Pearson’s correlation coefficient between BPH population density in 2 selected locations was positive with low association...
