Special Issue Information

Dear Colleagues,

Despite their small sown areas, sweet corn and sorghum are species of great economic importance. In the era of climate change, sorghum, characterized by extremely low water requirements and the possibility of obtaining satisfactory yields, can be an alternative species in cultivation, securing nutritional needs, especially for cattle. Sweet corn grain does not contain gluten, hence its participation in human nutrition will become increasingly common. Among the current problems of growing sweet corn and sorghum, their protection against agrophages is of particular importance. The greatest threat to crops is posed by weeds, which deprive crops of water and nutrients. In the protection of corn plants, when controlling weeds, the resistance of varieties of these species is critical due to the high phytotoxicity of the agents used. In the case of sorghum, for which there are no separate recommendations for the use of herbicides, it is extremely important to identify measures that are effective, yet selective for the cultivated varieties. Other agrophages (diseases and pests) also significantly affect both the yields obtained and their quality. Aspects of tillage for sowing the aforementioned crop species are currently the subject of much research. Hence, there is a need to present them in this thematic Special Issue.

Field pansy infestation can lead to a decrease in the species diversity of plant communities and to the disappearance of other species. Field pansy infestation is fairly common in many crops, including maize. Understanding the ecology and management strategies for field pansy in maize is essential for effective weed control. This research into sugar maize was conducted from 1992 to 2019 in the Research and Education Center Gorzyń, Złotniki branch, which belongs to the Poznań University of Life Sciences. The assessment of weed infestation was carried out in experiments that focused on chemical weed control in maize. The experiments were established as single-factor randomized block designs with four field replications. The aim of the study was to evaluate dynamic changes in the status and the degree of field pansy infestation in sugar maize that was cultivated after various other crops in the Wielkopolska region, with a focus on weather conditions. The results indicated that the probability of field pansy individuals occurring among the total number of weeds was highest when maize was cultivated after wheat, but the probability of such infestation did not significantly differ when maize was sown in a crop rotation after winter triticale.
