Cel' issledovaniy – povyshenie ravnomernosti raspredeleniya semyan v ryadke pri poseve zernovyh kul'tur za schet sovershenstvovaniya katushechno-shtiftovogo vysevayuschego apparata. Katushechno-shtiftovyy vysevayuschiy apparat, ustanovlennyy na selekcionnoy seyalke SSNP-16, prednaznachen dlya poseva semyan zernovyh kul'tur pri ih selekcionnom proizvodstve. Dlya opredeleniya kachestvennyh parametrov eksperimental'noy seyalki provedeny polevye issledovaniya. Provedenie polevyh issledovaniy osnovano na tradicionnyh programme i metodike. Programma vklyuchaet: ocenku neustoychivosti vyseva semyan, issledovanie ravnomernosti raspredeleniya semyan i rasteniy v ryadke, issledovanie dinamiki poyavleniya vshodov, opredelenie biologicheskoy urozhaynosti opytnyh po-sevov. Issledovaniya ocenki neustoychivosti vyseva pokazali, chto eksperimental'naya seyalka imeet bolee vysokie pokazateli po sravneniyu s bazovoy seyalkoy SSNP-16. Neustoychivost' vyseva eksperimental'noy seyalki ne pre-vyshaet 3%. Issledovaniya neravnomernosti vyseva semyan i raspredeleniya rasteniy v ryadke pokazali, chto ekspe-rimental'naya seyalka imeet bolee vysokoe kachestvo vyseva, chem bazovaya seyalka SSNP-16. Koefficient variacii intervalov mezhdu semenami sostavlyaet sootvetstvenno 53,8 i 64,5%, mezhdu rasteniyami – 58,1 i 72,3% sootvet-stvenno. Analiz nablyudeniy pokazal bolee vysokuyu intensivnost' rosta u rasteniy, poseyannyh eksperimental'noy seyalkoy, chem u rasteniy, poseyannyh bazovoy seyalkoy. Sravnenie biologicheskoy urozhaynosti pokazalo uvelichenie urozhaynosti pshenicy na 14-19% posle poseva eksperimental'noy seyalkoy po sravneniyu s posevami seyalkoy SSNP-16. V rezul'tate provedennyh polevyh issledovaniy vyyavleno, chto eksperimental'naya seyalka sootvetstvuet agrotehnicheskim trebovaniyam.
