초록
The study was initiated to compare seasonal nutrient variations and rice (Oryza sativa L.) productivity in each of leading rice farm with conventionally managed and recommended fertilized of the large-scale environment-friendly agricultural districts in Jangheung, Suncheon, and Okcheon provinces in 2017. Suncheon rice experimental farm plots included a recommended fertilization plot that had been additionally sown hairy vetch in the fall of previous year, while Okcheon rice farm included a recommended fertilization plot applying half amount of the compost in the conventional plot. A Jangheung rice farm only practiced crop-livestock farming system. Soil pH and EC in all experimental plots were suitable levels for rice growth to cultivate. Seasonal soil pH from March to September was the highest for Suncheon rice farm, and seasonal soil EC was the highest for Jangheung rice farm. Seasonal soil T-N increased in all the plots from March to June in particular for Suncheon rice farm, and Jangheung rice farm had the lowest seasonal soil P. Seasonal soil K decreased in all the plots, with the lowest levels observed for Okcheon farm. Seasonal soil NH4+ mostly increased by up to 90 mg/kg in Jangheung rice farm from March to June. Seasonal plant T-N, P and K concentrations were the highest for Jangheung rice farm. Seasonal plant T-N and P concentrations decreased from June to September, but K leveles were fluctuated between 2.0% and 2.5%. Seasonal SPAD value was the lowest in Suncheon conventional plot. Jangheung rice farm plot produced 6,303 kg of rice per ha, which was approximately two times higher than those of Okcheon recommended plot. The seasonal T-N, P and K balance was the highest in Okcheon conventional plot, with the lowest values observed for Suncheon conventional plot. As a result, Suncheon recommended plot showed relatively low levels of seasonal macro-nutrient balance and the highest rice production, which could be the most environmentally friendly farm practiced conducted in this study.
Abstract
The study was initiated to compare seasonal nutrient variations and rice (Oryza sativa L.) productivity in each of leading rice farm with conventionally managed and recommended fertilized of the large-scale environment-friendly agricultural districts in Jangheung, Suncheon, and Okcheon provinces in 2017. Suncheon rice experimental farm plots included a recommended fertilization plot that had been additionally sown hairy vetch in the fall of previous year, while Okcheon rice farm included a recommended fertilization plot applying half amount of the compost in the conventional plot. A Jangheung rice farm only practiced crop-livestock farming system. Soil pH and EC in all experimental plots were suitable levels for rice growth to cultivate. Seasonal soil pH from March to September was the highest for Suncheon rice farm, and seasonal soil EC was the highest for Jangheung rice farm. Seasonal soil T-N increased in all the plots from March to June in particular for Suncheon rice farm, and Jangheung rice farm had the lowest seasonal soil P. Seasonal soil K decreased in all the plots, with the lowest levels observed for Okcheon farm. Seasonal soil NH4+ mostly increased by up to 90 mg/kg in Jangheung rice farm from March to June. Seasonal plant T-N, P and K concentrations were the highest for Jangheung rice farm. Seasonal plant T-N and P concentrations decreased from June to September, but K leveles were fluctuated between 2.0% and 2.5%. Seasonal SPAD value was the lowest in Suncheon conventional plot. Jangheung rice farm plot produced 6,303 kg of rice per ha, which was approximately two times higher than those of Okcheon recommended plot. The seasonal T-N, P and K balance was the highest in Okcheon conventional plot, with the lowest values observed for Suncheon conventional plot. As a result, Suncheon recommended plot showed relatively low levels of seasonal macro-nutrient balance and the highest rice production, which could be the most environmentally friendly farm practiced conducted in this study.
