PRODUCTIVITY OF GRAIN PEA VARIETIES UNDER CHANGING WEATHER CONDITIONS IN THE AZOV ZONE OF THE ROSTOV REGION
2020
Lysenko, A.A.
The article presents the results of three-year observations in the Azov zone of the Rostov region on the influence of the main agrometeorological indicators (amount of precipitation, temperature, SCC of the growing season) on the grain yield and mass of 1000 seeds of pea. The yield and weight of 1000 pea seeds are largely dependent on the prevailing hydrothermal conditions per year of cultivation. Research results are presented that reflect the nature of the dependence of the studied indicators on changing weather factors. On average, over 3 years of research, the increase in the yield of the varieties: Sotnik, Premier, Alliance, and Cadet to the standard Aksaysky mustachioed 5 amounted to 5.4 - 6.4 c/ha. The obtained data can be used in the selection of source material for the creation of new high-yielding pea varieties that most fully realize the soil and climatic potential of the region and meet the requirements of agricultural production.
