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).

Cím:	Correlation analysis of relative chlorophyll content and yield of maize hybrids of different genotypes / Zagyi Péter, Tamás András, Rácz Dalma, Fejér Péter, Radócz László, Horváth Éva
Dátum:	2022

Megjegyzések:	In 2021, correlation between relative chlorophyll content and yield in three maize hybrids of different genotypes was examined. The data were collected at the Látókép Experimental Station of the University of Debrecen located on the Hajdúság loess ridge in Hungary. The soil of the small plot field strip plot trial, which was set up in 2011, was calcareous chernozem. Apart from the control treatment (without fertilisation), N fertiliser is applied in the form of base and top dressing. The base fertiliser containing 60 and 120 kg ha-1 N of nutrient applied in spring was followed by top dressing containing +30?30 kg ha-1 N in V6 and V12 phenophases. SPAD values measured at different phenological stages of the growing season increased by an average of about 28% up to 10 leaf stage for all three hybrids. In the pre-silking period (Vn), the relative chlorophyll content decreased by 8% on average. After an average increase of 14% in the tasselling and silking period, SPAD decreased by an average of about 29% at full maturity (R6). For the different fertiliser treatments, higher N doses resulted in higher yields. In the basal fertiliser treatment, the A 60 N dose resulted in an average 34% increase in yield, and the A 120 N dose resulted in an average 94% increase in yield compared to the control. The 60 kg ha-1 N basal fertiliser (A60) increased in the V6 phenophase with an additional 30 kg ha-1 N resulted in an average yield increase of 26%. When 120 kg ha-1 N of basal fertiliser (A120) was increased by an additional 30 kg ha-1 N in the V6 phenophase, only the Merida hybrid showed a significant yield increase (7%). No further yield increase was observed when V690 and V6150 treatments were increased by an additional 30 kg ha-1 N in the V12 phenophase. The yield of the Armagnac hybrid decreased by almost 20%, the yield of Fornad by 3% and the yield of Merida by 1%.
