Winter Wheat Resilience Under Different Pre-Crop Conditions in Albeluvisol Soils

One of the most popular varieties in crop farming is wheat. In Lithuania, more than 460 winter wheat varieties are registered in the State Register of Plant Varieties. One of the most popular and time-tested varieties is ‘Skagen’, which is highly valued for its winter hardiness. The aim of the research is to determine the influence of different pre-crops on the winter survival of the wheat variety ‘Skagen’ in Albeluvisol soils. For the experiment, fields of the winter wheat (Triticum aestivum) variety ‘Skagen’ from farms in the Lazdijai district were chosen. The experiment was conducted from 2017 to 2018. Plant count, chlorophyll index, and weed count were evaluated. After evaluating the differences in plant density after winter, it was found that a significantly greater reduction in plant density, 98.06%, occurred after winter wheat and 97.62% after spring wheat pre-crops compared to perennial grass pre-crops. The highest chlorophyll index was in winter wheat crops, where the pre-crops were peas, winter rape, and perennial grasses, respectively, ranging from 17.78% to 19.57%. Properly selected pre-crops reduce the risk of overwintering and form a strong crop from the beginning of vegetation.
