Abstract

This paper serves as a documentation of the field practice performed by the trainee at the International Rice Research Institute located at Los Baños, Laguna from May 9, 2011 to June 3, 2011. The main goal of this paper is to present the processes involved in moisture meters calibration and combine harvester operation. There are two methods in measuring moisture content, the primary, or direct method, often called the oven method, and the secondary method which uses electronic moisture meters. Oven method weighs a sample of the paddy and then removes all the moisture by heating the sample in an oven. Three moisture meters were calibrated relative to the oven method namely Kett Riceter, IRRI MArk II and MC-7825G moisture meter. The other thing that the trainee did was to observe harvesting operation. Harvesting is the process of gathering the useful portion of the crop from the field. Proper harvesting to maximize grain yield, and to minimize grain losses and quality deterioration. Combine harvester combines all operations such as cutting, handling, threshing and cleaning. Combine harvesters were used to harvest rice grains minimizing the time of operation and minimizing losses that is about one to two percent compared to manual harvesting with five to six percent losses. During the field practice, the trainee was exposed to the actual calibration process for the moisture meters and the combine harvesting operation.
