The research was conducted on efficiency of mechanical thresher over traditional method of threshing finger millet. Finger millet (Eleusine Coracana Craertn) commonly known as ragi is one of the important small millet crop grown in red soil areas of India. It is predominantly cultivated in southern parts of Karnataka. The process of seed damage starts right from harvest to storage. The traditional methods of threshing are tedious time consuming and inefficient in operation. The experiment was conducted with two ragi varieties (MR1 and HR911). Hence, mechanical threshing is a means to overcome the above problems. So as to evaluate the performance efficiency of mechanical thresher over traditional method of threshing finger millet and optimum threshing parameters for finger millet. Some of the important parameters which influence the threshing efficiency, mechanical damage, moisture content, threshing cylinder speed, feeding rate and concave clearance. The method of threshing was experimented at three different moisture content levels of ragi [around 18 to 19, 13 to 15 and 10% (w.b.)]. The mechanical ragi thresher has given the maximum grains output of 140.5 kg/h for variety MR1 and 130.3 kg/h for variety for HR911 as compared to traditional threshing methods.Keywords

A decision support system (DSS) is useful in generating alternate decision scenario for management of natural resources in an interactive and holistic way. The developed decision support system on runoff and soil moisture availability as a part of hydrological planning based on SCS curve number method uses the measured information on land use, soil type and rainfall. These conceptual decision and flow logic was formulated to link information through SCS curve number method and has transformed into a computer model using visual basic (VB) programming language. The output format provides daily rainfall and runoff and soil moisture status of the soil continuously for a given period of daily data. The DSS was validated for field scale land holdings of micro-watershed data and proposed for utilization by farmers and technocrats of line departments.Keywords
