“…As a rule, the reason for lodging with excessive soil moisture and mineral nutrition of plants (especially nitrogen) is the rapid stem growth in the shoot stage. This leads to its elongation and weakening and in the subsequent phases of development under adversity (heavy rain and wind) to lodging due to the bending of the lower part of the second internode [15]. In this case, the action of retardants consists in strengthening the lower internodes by their shortening and thickening, which makes the stem more resistant to lodging [16].…”

The results of field experiments on the effectiveness of the use of retardants Moddus and Messidor in the cultivation of spring barley at different levels of mineral nutrition are presented. The shortening of the second internode of barley plants by 3.3-24.1% and the increase in its thickness by 1.43.7% were established when using retardants Moddus and Messidor in different doses on a high nutrient content. The data obtained indicates positive effect of retardants on increasing the resistance of barley stems to unfavorable factors (rain and wind), which is confirmed by the results of assessing the degree of lodging. It was found out that the use of retardants on natural nutrient content in a dry growing season leads to the significant decrease in yields (from 0.22 to 0.94 t/ha). In slightly arid and excessively humid conditions of the growing season, the use of retardants on medium nutrient content provides the significant increase of the yield from 0.22 to 0.53 t/ha, on high nutrient content from 0.21 to 0.52 t/ha. In average, over three years of research, the highest yield of barley was obtained on high nutrient content when crops were treated with Messidor at a dose of 1.0 l/ha, Moddus at a dose of 0.4 l/ha. The best economic indicators were established when feed barley was cultivated on medium nutrient content (N15 P39 K39 + pre-seeding application of N68) using retardants Moddus at a dose of 0.2 l/ha, Messidor at a dose of 0.5 l/ha.

“…With lodging, plants have reduced photosynthetic surface area, slowing down the assimilation of nutrients and water. The grain has a low content of nutrients [9]. Mechanized harvesting of such plants is difficult.…”

In the course of field and laboratory research, selection samples of spring hexaploid triticale were studied for their selection-valuable traits and lodging resistance. The correlation analysis revealed a correlation between the individual traits that determine lodging tolerance. The most stable relationship of lodging resistance is with the length of the second and third internodes and the breaking strength of the straw. An additional selection criterion for lodging resistance is the sum of the lengths of the 2nd and 3rd internodes. Non-lodging varieties with high grain productivity that have significant differences in architectonics have been identified. These samples can be promising in lodging resistance selection without the involvement of sources of short stalkedness, having a number of negative traits.
