Seed productivity of the eastern goat husk depending on the seeding rate and seed treatment before sowing

Abstract

The article describes the experience of cultivating the eastern goat in the conditions of Western Siberia. The prerequisites for which were numerous experiments by domestic and foreign scientists, who testified that there is a problem of providing a feed base with high-protein feeds and, in particular, seed material. In Western Siberia, perennial grasses in the structure of forage crops occupy about 40 %, of which the eastern goat, despite its high performance, occupies no more than 7 %. The laying of the experience and the experimental work was carried out according to the generally accepted methodology of V.A. Dospekhova. Stem density measurements were carried out in the spring and before each harvesting of herbs. In the course of the study, phenological and morphological observations were carried out, as well as accounting for the yield of seeds of the Oriental goat. In the course of research, it was found that in the first periods of growth of development, there was no significant difference between the variants, changes occurred in the later stages, so with increasing age of the plant their height increased, this is especially noticeable in variants where the seeds were treated with rhizotorphin and micronutrients before sowing. Both the seeding rate and the presowing tillage affect the yield of the seeds of the eastern goat. For example, the optimal seeding rate was 0,6 million units/ha, while a change in this indicator both up and down caused a significant decrease in seed yield. The highest yield of goatgrass seeds (464 kg/ha) was noted at a seeding rate of 0,6 million units/ha using rhizotorphin. The lowest yield (169 kg/ha) was noted with a seeding rate of 1,5 million units/ha in the untreated variant (control).
