“…In order to utilize the potential productive capacity of hybrids as much as possible, the harmony of the agro-technical factors is necessary (Kovács and Sárvári, 2016). The low average yield in corn production can be due to the fall-back of chemical fertilization; this is why the use of fertilizers must be increased in order to reach higher and more consistent amounts of crop (KOMAREK, 2007; SÁRVÁRI AND PEPÓ, 2014, PEPÓ, 2017SÁRVÁRI, 2019; SÁRVÁRI ET AL., 2021). Foliar fertilization is a highly efficient crop fertilization method since it favours the assimilation of the nutrients in the plant and consequently, the utilization of the nutrients applied with the fertilizer, thus increasing crop yields and quality (TEJADA AND GONZALEZ, 2004; ABBAS AND ALI, 2011; OSMAN ET AL., 2013).…”

We examined the influence of foliar fertilization on the yield and grain quality of corn in 2018. The experiment was set in three replications, random blocks on the area of Tangazdaság Ltd. in Hódmezővásárhely. The soil of the experiment was meadow chernozem. We sprayed out three different foliar fertilizer products individually and combined with each other as well, so there were six treatments and the control to be examined. The year 2018 was not favourable for corn production. In 2018 the amount of precipitation in the vegetative period of corn was lower by 70.5 mm than the average. The mounthly average temperature in the vegetative period of corn was higher by 4 °C than the average of several year. We evaluated the obtained data by single factor analysis of variance. We obtained 10.33 t/ha in control treatment, and with the foliar fertilization the yield ranged between 10.52-11.40 t/ha. The foliar fertilization products increased the yield of corn, but this difference was not significant. By the application of foliar fertilization, the crude protein and starch content of corn grain did not change significantly. Our scientific results showed, that the foliar fertilization has positive effect on the yield of corn and small effect on the examined grain quality parameters

“…Fertilizer use plays an important role in increasing the yield of maize (Árendás, 2006;Sárvári and Pepó, 2014;Pepó, 2017). In particular, nitrogen fertilizer is a key element (Evenson and Gollin, 2003;Szulc et al, 2016) as it greatly influences the biomass and grain yield due to the development and durability of the leaf area (Muchow, 1998;Miao et al, 2006).…”

The effect of the amount and application date of nitrogen fertilizer on maize productivity and profitability was examined in a field experiment established on calcareous chernozem soil at the University of Debrecen in Hungary (47 o 33' N, 21 o 26' E, 111 m) under different environmental conditions in the wet crop year of 2016 and the average crop year of 2017. In addition to the non-fertilized treatment, N fertilizer doses were applied in the form of basal and top dressing. The 60 and 120 kg N ha -1 treatments applied as spring basal dressing were followed by two occasions of 30 kg N ha -1 top dressing at the V6 and V12 phenophases each. The longer maturity hybrid Armagnac (FAO 490) had a better conversion ratio concerning the precipitation during the growing season of 2016 (which was higher than the 30-year average), as well as the basal and top dressing (averaged over the different treatments) in comparison with the shorter maturity hybrid Renfor (FAO 320). In the wet crop year, the yield of Armagnac was 21.7% higher, while that of Renfor was 10.4% higher. The 60 kg N ha -1 basal dressing and the +30 kg N ha -1 top dressing at the V6 phenophase (V6 90 ) resulted in more efficient uptake and better conversion rate in the rainy crop year (2016) in the case of both examined hybrids. In the average crop year (2017), a difference was observed in the successfulness of top dressing. In the case of the Armagnac hybrid (FAO 490), top dressing did not cause any significant yield surplus and the 120 kg N ha -1 basal dressing was shown to be successful. In the case of the Renfor hybrid (FAO 320), the early top dressing (V6 150 ) applied on the basal dressing of 120 kg N ha -1 was favorable. The most favorable income of nutrient management (N) was provided by the basal dressing of 120 kg N ha -1 and the +30 kg N ha -1 (V6 150 ) top dressing applied at the early V6 phenophase, averaged over the examined hybrids and years. In the case of the Renfor hybrid (FAO 320), the highest profitability was reached with the V6 150 treatment, independently of the prevailing environmental factors. However, as regards the Armagnac (FAO 490) hybrid, the top dressing applied at the V12 phenophase provided the highest profitability, which could be achieved with the lowest dose of V12 120 treatment in the wet year (2016) and the highest dose of V12 180 in the average crop year (2017). Altogether, based on the results of yield and marginal revenue analysis, the recommended fertilization technology is basal dressing of 120 kg N ha -1 and basal dressing of +30 kg N ha -1 (V6 150 ) applied at the early V6 phenophase. The obtained findings also show that the effect of N is greatly affected by crop year, genotype, and other elements of the applied technology. Also, marginal efficiency has to be defined for each hybrid, considering the given crop year, too.
