The swine farming has a significant potential for biogas emissions and is a substantial contributor to greenhouse gas emissions within Vietnam's agricultural sector. This study was conducted to determine the total amount of CH4, and CO2 (eq) released from mature management activities and emission coefficients of CH4 and CO2 (eq) at different swine farms in Northern, Central and Southern regions, using tier 1 and tier 2 according to IPCC method.

The authors used prospective estimates of revenue and expenses for ordinary activities, obtained on the basis of a multiplicative trend-seasonal model to predict the profit of an agricultural enterprise. The study draws attention to the fact that the classical decomposition of the trend-seasonal model into trend, seasonal and random components is possible and convenient for forecasting the financial performance of an agricultural enterprise that has seasonality in crop and livestock production.

Developing new biofertilizers has been an area of great interest in modern agriculture. This study focused on actinobacteria possessing high chitinase activity, biofilm formation, plant growth promotion, and antifungal activity. Two chitinolytic actinomyces strains, YSS-3.3 and YWS-5.1, were isolated from soil and chitin flake samples collected from Yok Don National Park in the Central Highlands, Vietnam.
