Environment and digestate affect on the oats quality and yield parameters

Abstract

Oats are of great economic importance thanks to the high nutritional value of the grain. In this study, the productivity of oats was analyzed in two varieties: control (variants without digestate) and in the variant with digestate, during 2021-2022. The following parameters were tested: plant height, number of grains per panicle, grain yield per hectare and protein content. Highly significant positive correlation coefficients were found between grain yield and number of grains per plants (r=0.68**) and grain yield and plant height (r=0.59*). The results showed that year and digestate had no statistically significant effect on oat grain yield. The obtained values for grain yield were statistically significantly higher in the variant with digestate compared to the control variant. The digestate had a significant effect on the increase of oat yield and yield parameters, therefore its application in the oat crop is recommended.
