The Influence of Different Cultivation Technologies on the Changes in Quantitative and Qualitative Parameters of Buckwheat

Abstract

Changes of the quantitative and qualitative parameters of buckwheat were observed on gleyic Fluvisols (locality Milhostov, Slovak Republic) at different tillage between 2013 and 2015. The experiment was conducted using two soil tillage treatments: conventional tillage and reduced tillage, and three conditioner application treatments: soil conditioner PRP SOL, a combination of soil conditioner PRP SOL and plant auxiliary substance PRP SOL+EBV, and control.
In buckwheat crops, basic physical properties were also monitored. The statistically significantly higher yields of buckwheat were achieved with reduced tillage. Significant differences were found in buckwheat yield between years.
The lowest yields of buckwheat were recorded in the dry and extremely hot year of 2015. In the variant with conventional tillage, better values of basic soil physical properties were recorded compared with the reduced tillage. Significantly higher yields of buckwheat were found with applications of conditioners than in the control. The application of plant auxiliary substance PRP SOL+EBV on the variant with PRP SOL did not substantially increase the yields of buckwheat. The content of nitrogen substances in the grain of buckwheat was dependent on the fertilization options. Higher content of nitrogen substances in the grain of buckwheat was found in the control than with the application of conditioners. A negative correlation was found between the yield and nitrogen substances in the grain of buckwheat (r = -0.74).
