PEA PRODUCTIVITY DEPENDING ON CROPPING TECHNOLOGY IN THE UNSTABLE MOISTURE ZONE OF THE STAVROPOL TERRITORY

Abstract

In modern market conditions, crop-growing farms tend to reduce the cost of farmed products. This can be achieved by implementing resource-saving technologies. One of these technologies is direct seeding technology, where seeds are sown in soil without tillage. How-ever, to date, there have been no studies of pea cultivation without tillage in comparison with the technology recommended by scientific institutions. In this regard, the FSBSI North-

Caucasus FARC, which is located in the zone of unstable moisture on the Stavropol Territory, is conducting research on the effectiveness of pea cultivation without tillage. In the first year of research, it was found that the content of productive moisture is 17,3% higher by non-tillage technology. Moreover, the difference between the technologies in the one-and-a-half-meter layer was observed throughout the entire growing season. The soil density during flow-ering and full ripeness was the same for both technologies, but before leaving for winter, early in spring and during sowing, the density of the upper 0-10 cm of the soil layer according to the recommended technology was excessively low and amounted to 0,89-1,09 g/m3. With a large shortage of moisture during the growing season in 2019, the yield of peas was low and amounted to 1,06-1,21 tons/hectare. At the same time, technologies and doses of mineral fer-tilizers did not have a significant impact.
