Mục tiêu của dự án CARD 026/VIE-05 để nâng cao chất lượng và giá trị của lúa, thông qua một phương pháp tiếp cận tích hợp trong đó bao gồm nông dân, xay xát, các nhà cung cấp dịch vụ và cán bộ khuyến nông và tổ chức giáo dục. Từ tháng 4 năm 2006 đến tháng 11 năm 2009, dự án này đã tiến hành thí nghiệm trên thu hoạch thời gian và phương pháp, phẳng giường sấy, khô sôi giường, và hiệu suất xay xát. Đó là thấy rằng bất kỳ sự chậm trễ hoặc kéo dài thời gian thu hoạch có. | Collaboration for Agriculture and Rural Development CARD Program CONTROLLING RICE KERNEL CRACKING IN THE FIELD AND POST-HARVEST PROCESSES IN THE MEKONG DELTA Project title Investigation of rice kernel cracking and its control in the field and during post-harvest processes in the Mekong Delta of Vietnam Project code Card 026 05VIE Authors Vinh Truong1 Tuyen T.

From April 2006 to November 2009 this project conducted experiments on harvesting time and method flat-bed drying fluidised-bed drying and milling performance. It was found that any delay or longer harvesting time can cause more losses. An optimal harvesting time for highest head rice yield of some main rice varieties has been proposed by this project. The performance offlat bed drying was improved for bester rice quality. Fluidised bed drying followed by tempering above glass transition temperature of rice then tower drying or ventilation was found to be a potential drying technology for high moisture paddy. The milling is another important factor to improve the head rice yield. Dehusking using rubber roll will improve HRY in comparison to stone disc but only when the paddy is dried correctly up to moisture content of 14 . The systematically data collection and experimental results were prepared for training. There were total of 2392 farmers and 306 extension workers of Can Tho City and Kien Giang province participated in the training program. These extension activities had a very satisfactory impact on the farming practices of smallholder farmers and local extension workers. To .
