Cím:	Examination of the effects of climatic factors and location-specific N Fertilization on relative Chlorophyll content and yield of maize / Éva Horváth, Péter Zagyi, Károly Simon, Attila Vad, Adrienn Széles
Dátum:	2022
Megjegyzések:	The effect of climatic factors of the growing season on the chlorophyll content of maize was analysed in three years (2018, 2019 and 2020). The studies were carried out at the Látókép Experimental Station of the University of Debrecen in Hungary. The measurements were carried out under irrigated and non-irrigated conditions with the maize hybrid Sushi (FAO 340). Doses of 60 and 120 kg N ha-1 applied as spring basal fertilizer were followed by two top-dressings at V6 and V12 phenophases at rates of +30 and +30 kg N ha-1. The largest increase in SPAD value up to the R1 phenophase was measured in the A120 treatment (15.0). The largest crop year modification effect was observed in the V690; treatment (6.9). The treatment with 120 kg N/ha had the highest SPAD value increase (7.2). A strong correlation between fertilizer and SPAD value was demonstrated at the R1 growth stage in both irrigated and non-irrigated treatments in 2018 (r=0.913*; r=0.928) where fertilizer influenced SPAD values in 83% and 85%, respectively. The negative impact of the environmental factor was most pronounced in 2020 in the non-fertilised and basal treatments. Overall, in two years (2019,2020), the A120 treatment had a significant yield improving effect for the Sushi hybrid. With the exception of treatments V6150 and V12120, irrigation increased yield, with the highest increase of 1.58 t/ha-1 in treatment V690. A reliable difference between the two variants was found in the V12120 treatment (p <0.05), with a reduction of 1.13 t/ha-1. In the non-irrigated variant, the correlation was strong in the R1 growth stage in 2018 (r=0.818) and 2020 (r=0.863), where SPAD affected yield development in 67% and 74%, respectively. In the irrigated version, a strong correlation (r=0.865**) between SPAD value and yield was confirmed in 2018, during the silking period.
