Studies on Machine-Crop Parameters for Chickpea Seed Crop Threshing

Seed crop of legumes are very critical to mechanical abuses. Even minor injury to seed reduces major seed quality considerably. The protruding structure of chickpea makes it more critical. Also, timeliness is important factor in seed production system in light of weather vagaries. Further, conventional threshing operations always coupled with reduced recovery, labor consuming and uneconomical. The present study was conducted in view of to optimize important operational and crop parameters influencing the threshing of chickpea seed crop. Moisture content, concave clearance and cylinder speed were taken as independent parameters and visible injury, internal injury, germination percentage and threshing efficiency was studied as dependent parameters. Cylinder speed was found the most critical factor for affecting visible and internal injury extent. Moisture content adversely affected the internal injury levels in threshed seed. Cylinder speed: 8.94 m/s, concave clearance: 14 mm and moisture content: 10 per cent were resulted seed of optimum quality with minimal visible and internal injury coupled with optimum threshing efficiency

Forage Crops in Alaska

The foregoing report was reprinted from Alaska’s Agriculture and Forestry, Alaska Rural Development Council Publication No. 3, and the pagination has been changed. Alaska’s Agriculture and Forestry was published in December 1983 by Cooperative Extension Service, University of Alaska and U.S. Department of Agriculture Cooperating, Fairbanks, Alaska. Some of the information in this report represents contributions from research programs of other present and past Alaska Agricultural Experiment Station staff scientists, as indicated by text citations of numbered title s of publications in the reference list above. Foremost among these investigators are R. L. Taylor, W. W. Mitchell, A. L. Brundage, J. D. McKendrick, H. J. Hodgson, and A. C.Wilton.Forage crops can be defined as the aboveground growth (stems, leaves, and sometimes seed heads and immature seeds) of plants that are gathered and fed to herbivorous, domestic animals. Similar plant growth that is grazed directly by livestock in rotational or permanent pastures, but on a less extensive basis than rangelands, is also considered in this discussion. For the most part, forage crops are herbaceous (nonwoody) members of two large plant families—grasses and legumes. The grass family world-wide numbers about 5,000 species, but only about three dozen of these are important as forages. The legume family includes more than 12,000 species world-wide, fewer than 20 of which are considered to be important forage crops

Influence of machine-crop parameters on the threshability of sorghum

The threshing section on combine harvester or thresher machine affects grain and stalk separation performance.  The present study is conducted with view to optimize important operational and crop parameters influencing the threshing of sorghum.  In this research, the effects of cylinder speed with four levels (13, 17, 21 and 25 m s-1), concave clearance (5, 10 and 15 mm) and feed rate (420, 500 and 590 kg h-1) were investigated on  un-separated seed percentage, damaged seed percentage and germination.  Result of ANOVA showed that cylinder speed had a significant effect on unseparated seed percentage and damaged seed percentage (
