บทคัดย่อ: Risk factor assessment in crop production for food safety comprises water soil and agro-chemical application was studied in chili field. Chili var. super hot was grown under GAP and Organic Fields. Physical and chemical properties such as pH, electrical conductivity=EC, Fe++, Cu++, Mn++ as well as microbial contamination in irrigated water and produce cleaning water were analyzed. The result revealed that both of them showed acceptable standard, the irrigation water found 3 CFU/ml of coliform bacteria, while no coliform and E. coli was found in produce cleaning water. Phytoremediation studied of three water plants, namely Lemna trisulca L., Water hyacinth (Eichornia crassipes (Mart.) Solms. and Morning Glory (Ipomoea aquatica Foisk) were carried out in water containing 10 ppm Chlorpyrifos insecticide. The samples were analyzed by GT Test Kit 540 nm photo absorbance at 0, 1, 3, 5 and 7days; the results showed that Water hyacinth gave the highest efficiency of phytoremediation compared to Lemna trisulca and Morning Glory, respectively. The comparison of different organic fertilizers on chili var. Super hot production revealed that concentrate organic fertilizer from pig and chicken manure showed the highest scores of the height, bush diameter and total chili produce. Comparative yield was studied in the field block ST1 and ST7 of input management for the GAP and Organic Production, respectively of Babycorn var. SG 17 Super, Syngenta Seed Company Ltd. The organic condition study was done after organic chili harvested and green manure at soil preparing of ST7 field which chemical drift protecting with banana and citronella buffer row along the production field. The study of soil nutrition management with the high N content Organic Fertilizer 55 kg/rai was applied 3 times during soil preparing period, at 15 and 30 days after planting. The Organic Fertilizer was showed the low productivity of harvested yield, which significantly determinations by 1,152.4 kg/rai of total husky yield and 192.64 kg/rai. of total harvested ear. While, GAP soil nutrition management in the ST1 field by applying 55 kg/rai Organic Fertilizer during soil preparing period and twice applications with 10 kg/rai 16-16-16 chemical fertilizer at 15 and 30 days after planting. The result showed the higher significant total husky yield and total harvested ear 2,181.2 kg/rai and 244.88 kg/rai., respectively. The GAP soil nutrition management obtained the higher Husk and Ear Ratio than Organic Production, 9:1 and 6:1, respectively. The effect of soil mixture, organic fertilizer and materials were investigated in the organic production of hot chili var. Super hot, East-West Seed Company Ltd., under plastic net and shading condition. The study showed the significant plant growth that mixed soil SM1 (soil, rice husk and diary dung into 4:1:1 ratio) plus the top dress fertilizer treatment with the diary dung manure and rice meal, 1:1 ratio, 200 g/pot obtained the highest plant height and plant canopy. The mixed soil SM2 (soil, rice husk and dried pig dung manure after dipping for pig manure tea dung into 4:1:1 ratio) plus the top dress fertilizer treatment with the dried pig dung manure after dipping for pig manure tea, 200 g/pot obtained the highest total yield and market yield 1ม350.96 and 1,250.71 kg/rai, respectively. The various top dress fertilizer treatments of organic fertilizer and materials were investigated in the organic production of hot chili var. Super hot, East-West Seed Company Ltd., under open field condition following with the 15 days after mungbean green manure preparing. The study showed the highly significant growth that top dress fertilizer of the diary dung manure and rice meal, 1:1 ratio, 200 g/plant gave the highest plant height and plant canopy. The hot chili production under plastic net and shading condition revealed the larger canopy than the open field condition. The dried pig dung manure after dipping for pig manure tea, 200 g/plant obtained the highest total yield and market yield 938.05 and 864.92 kg/rai, respectively. All treatments however, presented the higher rejected yield more than the production under the plastic net and shading condition. The study in parallel and zigzag plantation with the various organic fertilizer treatments were investigated in the organic production of hot chili var. Super hot, East-West Seed Company Ltd., under organic production field compared with the organic transition production field. The study showed the highly significant growth that the diary manure fertilizer revealed the highest express in plant canopy, particular in organic production field. The organic fertilizer Power 5 was promoted the highest total yield and market yield of 895.3 and 853.8 kg./rai respectively in parallel plantation; 889.51 and 846.15 kg./rai respectively in zigzag plantation. The diary manure was obtained the highest total yield and market yield 732.3 and 672.7 kg/rai, respectively. All treatments however, trended to produce the higher yield in parallel plantation, particular in the organic production field that showed the higher yield more than the transition organic field. The pest management plan was prepared based on the comparision data of organic inputs from various organic web sites as Thailand, Europe and USA. Plant oils and copper compounds are showed similar purpose on pest control whereas some chemical compounds of plant extracts such as azadirachtin, rotenone, nicotin and pyrethrin can be use under the standard of organic from Thailand. Plant oils as volatile oil extracted from Galanga (Galanga indica) rhizome showed there efficiency on inhibition of fungal mycelial and spore germination at the concentration above 800 ppm. The treatments of galangal oil, Bion as plant inducer and chemical fertilizer (15-15-15) were tested on pest management in chili plantation under organic standard. The experiments were set on two distinguish density as high density system (0.44 sqm/plant) and low density system (0.57 sqm/plant). Chili seeds were sow under nethouse conditions and the seedlings were set into the prepared land (mixing with manure and bone fertilizer). The result showed that yield from the high density plantation was a slightly low compare to the yield from low density plantation. Bion treated chili was found lower in numbers of pest infected and was given healthy fruit in a high ration whereas in treated of volatile oil from galangal and chemical fertilizer were less efficiency.
