The relationship between the nutrient supply and the yield of maize hybrids with different genetic traits on chernozem soil in variant years
Published March 5, 2015

The experiments were set on lime-coated chernozem soil in 2013 and in 2014, in our study four hybrids were included with different FAO number. We studied the effect of NPK fertilization and row spacing on the yield. The fertilizer doses were based on a 25-year longterm experiment. Compared to control, the N40 +PK treatment has also achieved a s...ignificant yield increase, although some hybrids responsed with yield loss to the increasing fertilizer doses; this effect was observed especially in 2014. The majority of hybrids reached higher yields in both years using the 50 cm row spacing. The water release of hybrids was measured weekly during the maturation, at the same time points. The rainy September slowed ripening and the water release of the hybrids in 2013, so the grain wet content at harvest showed higher values. The moisture contents were increased for some hybrids, in spite of the positive and favorable dynamic of water loss.

Evaluation of decreasing moisture content of different maize genotypes
Published June 30, 2018

An experiment was conducted to evaluate the decrease in grain moisture content in three maize hybrids in Debrecen in 2017. Armagnac, Sushi and Loupiac were the examined hybrids in this study. The culture medium and temperature conditions were applied uniformly for all three hybrids. According to the results obtained from the ratio of moisture c...ontent of seeds per day, the Armagnac variety in the intensive drying down phase loses more time and moisture content, so it can be concluded that the produced dry matter is more than in the case of other varieties. Armagnac requires more time to achieve yield, while the Sushi and Loupiac hybrids produce less harvest. Regarding the slope of the regression line, the rate of loss of moisture in the grain has been negatively correlated with the amount of “b” in the three examined hybrids. In regression analysis, the coefficient of explanation showed that the effect of day in the Armagnac was 97% in the Loupiac, 95% and in the Sushi 90% of the total dynamic value of moisture motion.
