Sunflower threshing is one of the most interesting field processes for making sunflower ready seed handling, drying, cleaning and oil extraction. One biggest problems observed during process accumulation threshed crop on first third roller passing off some unthreshed parts heads. To solve aforementioned problem optimize efficiency process, this research was focused devising testing a machine wi...

Abstract Current knowledge of the origins and routes introduction both tetraploid hexaploid free-threshing wheats (FTWs) from western Asia into Europe remains imprecise. Archaeobotanical distinction ploidy level is often dependent on sparsely recovered rachis segments, while more specific identification cultivars within groups using morphological characteristics either grain or chaff generally ...
