In their statement, they wrote that sweet corn is Hungary’s most important field vegetable crop, and its cultivation requires favorable ecological conditions and intensive agrotechnology. At the same time, the agronomic and economic efficiency of its cultivation has deteriorated significantly in recent years. The aim of the four-year (2021-2024) project was to develop complex technological models that would help increase the yield of sweet corn and produce quality raw materials for a market segment that plays an important role in preserving and improving human health. The project involved production plants and the teaching and research units of the University of Debrecen. The effects of different nutrient supply systems on the yield and quality of sweet corn were examined in three plants under irrigated and non-irrigated conditions, they wrote. Model experiments carried out within the framework of the project using technologies of different intensities proved that outstanding yields – 27.8-29.3 tons per hectare – could be achieved through the interactive, complex use of the project’s research results, they explained.

Based on detailed economic analyses of the results of small- and meso-plot and field experiments, it was determined that profitable sweet corn cultivation requires intensive agrotechnology, the two main elements of which are nutrient and water supply

The effects of lutein and zeaxanthin found in sweet corn were investigated in the Institute of Pharmacology and Pharmacotherapy of the Faculty of Medicine in the prevention and treatment of retinal damage caused by ischemia/reperfusion, age-related eye damage and other age-related diseases, such as cognitive decline, metabolic and cardiovascular diseases – the announcement reads.

Based on the preliminary analyses, five different lutein- and zeaxanthin-containing hybrids were selected

Their use as a food supplement was optimized by developing detailed protocols. During the experiments, the body weight, blood sugar level, glucose tolerance, cognitive functions, cardiovascular status and visual function of the experimental animals were monitored. The results of the research have proven that regular consumption of sweet corn with adequate content does not increase the risk of obesity or diabetes, and at the same time, its high lutein and zeaxanthin content may contribute to maintaining eye health. Ongoing molecular, histological and other studies may provide additional valuable information – the university’s statement concludes.
