Cím:Effect of abiotic stress factors on quality parameters of sweet corn (Zea mays L.convar.saccharata Koern.) / Károly Simon, Éva Horváth, Péter Zagyi, Péter Fejér, Adrienn Széles
Dátum:2022
Megjegyzések:In the scope of the research, it was aimed to examine the nutritional values of sweet corn (Zea mays L.convar.saccharata Koern.) in relation to heat sum and to determine, on the basis of the measured parameters, the optimum maturity time of maize, which will allow the practicing farmers to produce the best quality product. In the scope of the studies, relative chlorophyll content (SPAD), NDVI, LAI and soil moisture values were measured in different phenophases of maize (V6, V12, R1) in the year 2021. The experiment was set up in Fejér County, Hungary (N 46047'56'';E 18048'48''), in the field of our own farm (SIMON Ltd.), with an area of 21 ha. In the scope of the experiment, two maize hybrids (Dessert R72, Dessert R78) were tested in 4 replicates. The highest statistically verifiable SPAD and NDVI values were measured for both hybrids during the 12-leaf stage (p<0.05). In the case of both the Dessert R72 and Dessert R78 hybrids, N incorporation was continuous. Between V6 and V12 phenophases, the Dessert R72 hybrid showed higher nutrient incorporation dynamics (+17.55 SPAD) than the Dessert R78 hybrid (+13.73 SPAD). In R1 phenophase, N incorporation in vegetative parts decreased. Figuresynthetic activity increased between V6 and V12 phenophases, but NDVI decreased between the V12 and R1 phenophases. LAI value increased steadily with vegetation progression in both hybrids and was highest at the 50% silking (R1) stage (p<0.05), with Dessert R78 hybrid having more pronounced growth dynamics (3.38).
