PRODUCTIVITY OF BARLEY VARIETIES IN VARIOUS SOWING OPTIONS
2021
Golova, T.G. | Ershova, L.A.
The climate of the Voronezh region, located in the southeast of the Central Black Region, is sharply continental, with uneven precipitation over the years and during the growing season. One of the ways to achieve potentially possible yields is to assess and develop sound agrotechnical techniques that allow you to control the production process of a particular variety, making it less dependent on external factors. The main task of the study was to identify the optimal sowing rates, taking into account the use of mineral fertilizers during sowing. The characteristics of the zoned varieties are given according to the elements of productivity and grain quality. It was found that in the medium arid conditions of the Voronezh region, which occur most often, the sowing rate of 4.0 million seeds is effective. Over the years of studying local varieties, Talovskiy 9 and Ikorets were more productive in this sowing option. In the intensive varieties Priazovsky 9 and Ikorets, the increments against the fertilized background are more convincing: 6.2 and 6.5 c / ha, respectively. It was found that the greatest contribution to the formation of productivity is made by structural elements: the mass of grain per plant (ґ = 0.77 *** - 0.87 ***) and the mass of 1000 grains (ґ = 0.82 *** - 0.92 ***). It was found that in the variants with a reduced sowing rate – 4.0 million seeds, the vitreousness of the grain is noticeably higher, its value decreased with the use of fertilizers, more significantly in the variants with a sowing rate of 5.0 million. in a dose of 30 kg a.i., effective when growing forage and forage and brewing varieties.
