Results of 11-year investigations with winter rape cultivated in the 6-field crop rotation (sugar beets - maple pea - spring barley - winter rye - winter rape - winter wheat), 3-field crop rotation (winter rye - winter rape - winter wheat) and monoculture are presented. The experiment was carried out on soil lessive of the good ryeland complex at Mochełek near Bydgoszcz. It has been proved that shortening...
Experiments were carried out in 1972 to 1983 Laskowice, Wielichowo and Osiny on potatoes grown in crop rotation and in increasing monoculture. It has been proved that it is possible to get high, fairly stable potato yields in monoculture only on fields free from Globodera rostochiensis Woll. It has been found that on fields infected with nematodes, the cultivation of potatoes in a periodic or permanent...
В точном статическом полевом опыте с 4-летней монокультурой кукурузы проведенном в 1977-1980 гг. сравнивали типичную плужную обработку с мелиоративной вспашкой и углубленной обработкой как однократными мероприятиями сильно дифференцирующими подпочву. Исследования проводились на почве образованной из слабых и более сильных супесей. Интенсивные мероприятия по обработке существенно дифференцирующие объемную...
B опыте с монокультурой кукурузы возделываемой на зерно в период 1977-1980 гг. сравнивали следующие системы обработки: типичная плужная обработка (контроль), беспахотная обработка (только тяжелая борона до посева), ротационная почвофреза на глубину 12 см после уборки и предпосевно; углубленная обработка (зяблевая вспашка с углубителем). Дифференцияцито обработки модифицировали исследуемые физические...
