Cím:	Effect of the year on the yield components of "Szabolcs" triticale (x Triticosecale Wittm.) variety in a nitrogen fertilization experiment / Tamás Sipos, Andrea Györgyiné Kovács, István Henzsel, László Zsombik
Dátum:	2023
Megjegyzések:	The nitrogen nutrient supply of cereals is one of the important factor in determining the yield quantity and quality parameters, and it can be decisive for the economics of cultivation. Many results have been obtained for the scientific basis of professional fertilizing about winter wheat in Hungary, but there are few experimental results available about triticale. Triticale can be grown using fewer chemicals (fertilizers and pesticids) than winter wheat, its cultivation involves less environmental impact and it is suitable for the production of healthier food raw materials and feed. Since 2013 we have been studying the effect of nitrogen fertilizer on grain yield, yield components and baking quality of Szabolcs triticale variety in field experiments at the University of Debrecen, Institutes for Agricultural Research and Educational Farm, Research Institute of Nyíregyháza. Now we studied the effect of nitrogen nutrient applied in different doses and in different phenological stages on the grain yield components of triticale. The nitrogen fertilizer was applied in the form of Calcium ammonium nitrate (0, 50, 100, 150, 200, 250 kg N/ha) at 3 times (before sowing in autumn, at the time of tillering and at the beginning of earing), divided in different proportions. The fertilizer treatments were set up in a randomized block arrangement with four replicates, the plot size was 1.2 m x 9.2 m, the applied triticale seed dose was 4.5 million germ/ha. We present the results about the Szabolcs triticale yield components parameters (number of ears, length of ears, number of seeds per ear, weight of seeds and weight of 1000 seeds) recorded in two crop years with different amount of precipitation. In the spring of the first year the amount of precipitation was average (276 mm in I.-V. months), but the similar period of the second year was characterized by a drought (140 mm in I.-V. months), which determined the utilization of spring nitrogen fertilizer. We detected a significantly positive effect of early spring nitrogen top dressing on the number of ears per meter and the length of the ears with average water supply. The number of grains per ear was increased by all nutrient treatments in every application date, but the effect was statistically verifiable only in the case of treatment applied at the time of earing. The nitrogen fertilizer used before sowing and during the period of tillering had no effect on the seed weight per ear. Nitrogen top fertilizer applied at the beginning of earing resulted in a 3.5-11,4% increase in grain yield per ear, but the differences compared to the control could not be verified statistically. The first top-fertilizer treatment in spring resulted moderate decreasing at the thousand-seed weight, but the second treatment increased this yield component, but in both cases, the differences were not significant. Summarizing our results we found that nitrogen top dressing has a significant effect on the crop yield production of triticale, and its effect strongly depends on the amount of precipitation following its application.
