INFLUENCE OF SOWING TIME AND SEEDING RATES ON BUCKWHEAT GRAIN YIELD IN THE CONDITIONS OF AKMOLA REGION

Abstract

Given the trends of recent years, buckwheat for food and feed purposes is very popular. However, one of the problems is the technology of its cultivation, since in the conditions of climate change, especially in the dry steppe and steppe zones of Kazakhstan, the use of early recommended cultivation methods does not always lead to the expected results. The yield of buckwheat is affected by the timing of sowing and moisture availability, in this regard, the relevance of the presented article is to determine some methods of agricultural technology that ensure stable yields of buckwheat in the conditions of the steppe zone of the Akmola region. The goal was to determine the effect of sowing dates and seeding rates on the yield of buckwheat grain of the Shortandinskaya 4 variety. The experiments were set up using the classical methods of field experiments, based on the principles of observing a single distinction. Observations of plants were carried out according to the method of State Variety Testing. Field germination of buckwheat seeds varied from 78.9 to 82.7%; on variants with a smaller seeding rate (1.5 million), field germination rates were slightly higher than with seeding rates of 2.5 and 3.5 million pieces. per 1 ha, that is, seeding rates did not have a significant impact on field germination. The optimal time for sowing buckwheat seeds for the formation of potentially high yields was the third decade of May, with a norm of 2.5-3.5 million pieces. germinating seeds per 1 hectare.
