The Economic Benefit of Chicken Manure Utilization in Fish Production in Thailand

چکیده
The Pond Dynamics/Aquaculture CRSP has conducted basic research since 1983 on the biological and chemical factors that influence fish production. The goal of these studies is the improved well-being of farmers that adopt new aquaculture technologies. The ultimate test of the value of the research results generated is if farmers themselves demonstrate the economic benefit by incorporating new technologies into their farming systems. Therefore, economic analysis of the costs and benefits to the farmer of the various technologies developed will provide insight into the value of these technologies to farmers.

متن کاملEffects of manure nitrogen on vegetables’ yield and nitrogen efficiency in Tanzania
Due to an increasing demand of leaf vegetables, and hence their economic importance in the tropics, it is very common that excessive fertilizer N rates are applied to vegetable gardens and fields to attain high yield. This calls for more information on their nutrient requirements. In this study, we designed experiments to explore the effect of organic N levels on the yield and agronomic N use e...
