ABSTRACT
The experiment was conducted on rice with high enriched compost. It was conducted at Ban Kuankut, Tambon Kuanmapao, Pattalung province during December 2008-June 2010. The objectives of the study were to extend to use high enriched compost in organic rice area, to observe the effective of high enriched compost on growth and yield of organic rice, and to analyze the economic return. An experiment was conducted using observation trial and composted of 3 treatments: 1) apply 200 Kilogram per Rai of compost in the broadcast wet-seeded rice field, 2) apply 300 Kilogram per Rai of compost in the broadcast wet-seeded rice field, and 3) apply 200 Kilogram per Rai of compost in transplanting by hand field. The results showed that applying higher rate of the high enriched compost gave the higher yield. And the yield in the broadcast wet-seeded rice field was higher than that in the transplanting rice field. The high enriched compost promoted the chemical properties of soil. The results showed that Nmineralization increased according to the increasing of high enriched compost rates. The highest percent of income was found in the treatment that applied 200 Kilogram per Rai of high enriched compost in the broadcast wet-seeded field. So, application of 200 Kilogram per Rai of high enriched compost in the broadcast wet–seeded rice should be recommended.
