Baan Prao Subdistrict, Pa Phayom District, is considered an important source of rice and water in Phatthalung Province, or there are various types of rice cultivation, both in-season rice field and off-season paddy field, because of irrigation system in Ban Bo Sai Community, located in Ban Prao Subdistrict, Rice Varieties RD79 cultivations and rice farming for several consecutive years, and use of 16-20-0 fertilizer and 46-0-0 urea fertilizer every year. As a result, the researchers wonder whether rice cultivation in the each-year climate conditions and water quality in the rice fields affects the length and weight of the grains and the nutritional value of the rice. This project research aimed to study soil quality, water quality, climate conditions and nutritional value of the rice gained from in-season rice field cultivated in September 2020 and harvested in February 2021. The samples used in this research were collected in 1 rice field, 5 points, 5 repeats each. It was found that the nitrogen and phosphorus contents in the soil before planting were low, and potassium content was moderate. For water quality, pH was an average of 3.54, and turbidity was 25.9 cm with the average water temperature of 13.51 °C. For air quality, the highest average temperature in September was 33.5 °C, and the lowest temperature in October was 31.0 °C, as well as grains with length of 7.0-1.29 mm, and grains were most found to length of 10.0-10.9 mm, accounting for 36 percent. The weight of grains was not different, but the value was in the range of 20-30 mg. For nutritional value, energy was 354.04 kcal per 100 grams; 76.59 grams of carbohydrate per 100 grams; 7.36 grams of protein per 100 grams; 2.08 grams of fat per 100 grams; and 10.30 grams of fiber per 100 grams.
